CS Demo Manager is a companion application for managing Counter-Strike demo files — the .dem replays recorded by CS:GO and CS2. It gives you a single place to organize those files and then do something useful with them: pull out statistics, locate grenade lineups, build heatmaps, track VAC bans, generate videos, download recent demos, search for specific plays, and export the underlying data. It's aimed at players and teams who want to review their own matches or analyze others' without manually scrubbing through raw demo files.

What it is

A desktop app that sits alongside Counter-Strike and works on the .dem files the game produces. Instead of treating each demo as an opaque file, it indexes and processes them so you can query and visualize what happened inside.

The project publishes its own documentation, download page, changelog, and blog, so version history and setup instructions come from the source rather than third parties.

Core things you can do

Extract statistics from demos

Parse a demo into match statistics rather than watching it back in real time. This is the baseline feature the rest of the tooling builds on.

Find grenade lineups

A grenade finder is designed to quickly surface smokes, flashbangs, and similar utility usage — useful when you want to copy a lineup or check how a round was set up.

Generate and export heatmaps

Produce heatmaps from demo data and export them, which is handy for showing positioning tendencies across many rounds or matches.

Track VAC bans

A VAC tracker lets you follow ban status, relevant if you're checking accounts you've played against.

Extra features

The search and export features are what turn a pile of demos into something you can filter and report on — for example, isolating every ninja defuse across a season, or exporting round data to a spreadsheet for a coach.

How to get started

1. Go to the project's site and open the Download page to get the application.
2. Check the Docs for setup and usage details.
3. Point it at your demo files (or use the demo download feature to fetch recent ones).
4. Pick a task — stats, grenades, heatmaps, or search — and work from there.

The Changelog and Blog are worth checking when something behaves unexpectedly, since behavior changes between versions.

Who it's for

• Players reviewing their own matches and utility usage.
• Teams and coaches exporting round data and building heatmaps for prep.
• Analysts who want SQL access to demo data instead of manual review.
• Anyone who needs to find a specific play (a 5K, a ninja defuse) across many demos.

If you only ever watch demos inside the game client and never need stats, exports, or search, this adds little. If you regularly handle more than a handful of .dem files and want to query them, it's built for exactly that.

An app is a software program built to perform a specific set of tasks for a user, usually on a phone, tablet, or computer. The word is short for "application," and it covers everything from a calculator on your phone to a professional design tool. You choose the right one by matching it to your platform, checking what data and permissions it asks for, and reading recent reviews from people with the same device you own. If you only need to look something up once, a website is often enough; if you will return to the same task repeatedly, an app is usually the better fit.

App vs. website vs. desktop program

These three terms overlap, so it helps to separate them by where the software runs and how you get it.

A web app and a website can look identical. The practical difference is whether it is designed to behave like software — saving state, working offline, sending notifications — rather than just displaying pages.

Native, web, and hybrid apps

The build method affects how an app feels and what it can do.

• Native apps are written specifically for one platform. They tend to be the fastest and most reliable, and they get new platform features first. The trade-off is that a developer must build and maintain a separate version for each platform.
• Web apps are built with standard web technology and run in a browser. One codebase serves everyone, but access to hardware and background features is limited.
• Hybrid apps wrap web code inside a native shell. They are cheaper to ship across platforms, but performance and polish can lag behind native, especially for graphics-heavy work.

For a design or icon tool, this distinction matters: precise input, color accuracy, and smooth rendering are easier to guarantee in a native build. The Iconfactory, for example, describes itself as crafting icons, apps, and user experiences across more than 25 years of client work, which is the kind of long-running studio track record worth checking when an app's visual quality is the point.

How to choose an app: a checklist

Run through these before you install anything.

1. Platform compatibility. Confirm the app supports your exact OS version and device. A listing that says "iPhone" may not cover iPad or Mac without a separate purchase.
2. Permissions. Ask what each permission is for. A note-taking app requesting contacts or continuous location is a mismatch worth questioning.
3. Privacy and data handling. Look for a privacy policy and, on Apple platforms, the App Privacy labels that summarize data linked to you.
4. Cost model. Determine whether it is free, paid up front, subscription, or free with in-app purchases. "Free" often means ads or a locked feature set.
5. Reviews and update history. Sort reviews by most recent, not most helpful. An app last updated years ago is a risk on a current OS.
6. Developer identity. A named studio with a website and support channel is easier to trust than an anonymous listing.

Installing, updating, and removing apps

The steps are similar across platforms, but the entry points differ.

• iOS and iPadOS: Install from the App Store; update under Settings → General → Software Update or the App Store's update list; remove by long-pressing the icon and choosing Remove App.
• Android: Install from Google Play or a trusted APK source; update in the Play Store's "Manage apps" section; uninstall by long-pressing the icon or via Settings → Apps.
• Windows: Install from the Microsoft Store or the vendor's installer; update through the Store or the app's own updater; uninstall via Settings → Apps → Installed apps.
• macOS: Install from the Mac App Store or a signed download; update through System Settings or the app itself; remove by dragging from Applications to the Trash, then emptying it.

Expected result: after install, the app appears in your launcher or Applications folder and opens without a permission prompt loop. If it does not, the install did not complete cleanly.

Common app problems and fixes

• Crashes on launch. Force-quit, restart the device, then check for an update. If it still fails, the app may not support your OS version.
• Excessive permissions. Revoke anything unrelated to the core function in your device's privacy settings. The app may lose a feature, but it should still run.
• Fake or clone apps. Verify the developer name matches the official site, check download counts, and be suspicious of apps that mimic a popular title with slightly altered spelling.
• Battery or data drain. Review background activity and restrict background refresh for apps that do not need it.
• Payment confusion. Check whether a subscription auto-renews and where it is managed — store billing and direct billing cancel in different places.

A quick decision rule

Choose a native app when you need speed, offline access, or device hardware. Choose a web app when the task is occasional or you want the same experience on any machine. Choose a desktop program when you need files, keyboard shortcuts, and heavier processing. And before committing to any of them, spend two minutes on the developer's track record and the most recent reviews — that is where most bad choices are avoided.

Crossword Weaver is a Windows-only crossword puzzle maker that produces two distinct puzzle styles: free-form puzzles built from only your words, and themed symmetrical newspaper-style puzzles. It fits you if you work on Windows, want printable and playable output, and are willing to test the demo before deciding on a purchase. It is a weaker fit if you need macOS or web-based tools, or if you want a free alternative without evaluating paid software.

What Crossword Weaver Actually Does

Crossword Weaver is described as a tool for making two styles of crossword puzzles:

• Free-form puzzles — built using only your words, without forcing a symmetrical grid.
• Themed symmetrical newspaper-style puzzles — a more structured layout that resembles traditional published crosswords.

The software targets Windows only. Output is described as printable and playable, and the product is positioned as a maker, builder, and creator tool with automatic features. A demo is available so you can see whether it meets your needs before committing.

The Two Puzzle Styles, Compared

If your audience expects a classic newspaper look, the symmetrical style is the closer match. If you just want your own word list turned into a solvable puzzle with minimal layout fuss, free-form is the simpler path.

Platform and Compatibility Check

Before anything else, confirm you are on Windows. Crossword Weaver is Windows-only, so Mac, Linux, Chromebook, and browser-only workflows are out unless you have a Windows environment available. This is the single most common reason the tool is the wrong choice — not the puzzle features, but the operating system.

Evaluate With the Demo First

The site explicitly offers a demo to see if the software meets your needs. Use it to test the things that matter for your use case:

1. Build one free-form puzzle from a short word list and check the output.
2. Build one themed symmetrical puzzle and compare the layout to what you actually need.
3. Print or play the result to confirm the output format works for your audience.
4. Note any friction in the word-entry or layout process before deciding.

This demo-first path is the intended evaluation route, so treat it as the deciding step rather than relying on feature lists.

How It Compares to Alternatives

Use the same dimensions when weighing Crossword Weaver against other options:

• Platform: Crossword Weaver is Windows-only. Free web-based makers usually run in any browser but may offer less layout control.
• Puzzle styles: The two-style approach (free-form plus symmetrical themed) covers both casual and publication-style needs. Many simple free tools only do one style.
• Output: Printable and playable output is claimed here. Check whether an alternative gives you the same export and play options.
• Cost: Crossword Weaver involves a purchase. Free alternatives exist, so weigh the price against the layout control and Windows-native workflow you get.
• Evaluation: A demo lets you test before buying. Free tools need no commitment but also no trial period.

Which Choice Fits You

• Choose Crossword Weaver if you are on Windows, want both free-form and symmetrical themed puzzles, value printable and playable output, and are willing to try the demo and then purchase.
• Look elsewhere if you are not on Windows, need a free tool, or only need a single simple puzzle style that a browser-based maker already handles.

The deciding factors are platform, the two puzzle styles, and whether the demo output matches your audience or publication. Test those three before committing.

CadHub is a browser-based community hub for Code-CAD — CAD modeling done by writing code rather than dragging geometry in a graphical editor. You can try several Code-CAD packages without installing anything locally, browse parts other people have published, fork their work to modify it, and ask the original authors how they built something. It fits you if you want to test whether code-driven parametric modeling suits your workflow, or if you already write OpenSCAD/CadQuery/JSCAD and want a place to share and remix parts.

What "Code-CAD" means here

In Code-CAD, a model is a script: dimensions and shapes are expressed as variables, functions, and operations, and the geometry is generated when the script runs. That makes parts parametric by default — change a number, get a new size — and makes designs diffable and forkable like any other source file.

The excerpt on the site shows this directly. A pumpjack walking-beam module declares its own parameters at the top:

module beam(r1, r2, shr, msr){
  H = 12; // Height
  W = 10; // Width
  e = 10; // Total added extension
  ...
}

The comment lines are the interface: anyone reading the part can see which values are meant to be tuned.

Which tools you can use

CadHub presents three integrations as available today, with more indicated as coming:

The practical choice: pick OpenSCAD if you want the most mature CSG library and a large body of existing examples; pick CadQuery if you already write Python and want sketch-based workflows; pick JSCAD if you're a web developer and JavaScript is the path of least resistance; consider Curv if your goal is mathematical/artistic form rather than mechanical parts.

What you can actually do on the platform

• Try a package before committing to it. The site frames this as the main entry point: "try out Code-CAD packages to find the one that's right for you."
• Browse published projects. A project feed is shown on the page (loading state visible), with parts like the OpenSCAD pumpjack and a parametric hinge.
• Fork and remix. CadHub describes itself as a social platform: you can fork someone's work "to put your own spin on it."
• Ask the author. You can ask users how they designed a particular part — useful when a script's structure isn't obvious from reading it.
• Learn from real scripts. The hinge example on the page shows a common pattern: derive dependent values from inputs, then build the body from a profile.

hingeHalfExtrudeLength = hingeLength/2 - clearance/2;
mountingHoleMoveIncrement = (hingeLength - 2*mountingHoleEdgeOffset) /
                            (mountingHoleCount-1);

Reading a few of these teaches the idiom faster than a tutorial, because you see how someone else parameterized a real part.

How it differs from general CAD and from an ordinary web app

• Versus GUI CAD (Fusion, SolidWorks, etc.): the model is text, not a feature tree of mouse operations. You get version-controllable, parameter-driven designs; you give up direct manipulation and, depending on the tool, some surfacing and assembly conveniences.
• Versus a generic web application: CadHub isn't a general productivity app — it's specifically a host and community for Code-CAD scripts, with per-language integrations rather than one universal editor.
• Versus running these tools locally: the appeal is skipping installation and setup, and getting community and forking built in. The trade-off is that you're working within the platform's supported integrations and its web environment rather than your own full local toolchain.

Where to start

1. Open CadHub and look at the three integrations offered.
2. Pick the one whose language you already know, or the one whose modeling style matches your part (CSG-only vs. sketch-based).
3. Open an existing project in that language and read the parameter block at the top — that's the part's control panel.
4. Fork it, change one parameter, and re-run to confirm you understand the input → geometry relationship.
5. If a design decision is unclear, ask the author; that's an intended use of the platform.

One caveat worth stating plainly: the site describes the community as "making CAD easy to learn on the web," but Code-CAD still assumes you're comfortable reading and editing code. If you've never written a script, expect a learning curve before the parametric payoff arrives.

A Counter-Strike demo is a .dem replay file that records a match so you can rewatch it from any player's perspective, free camera, or overview. You manage demos by collecting the files (from Valve's servers or third-party platforms), then loading them into a tool that can parse them — CS Demo Manager is one such companion application, and it handles downloading, stats extraction, grenade finding, heatmaps, video generation, and export to XLSX/JSON/SQL.

What a .dem file actually is

A demo is not a video. It's a recording of the game's network data — player positions, shots, utility, round events — that the game engine replays. That distinction matters for what you can do with it:

• You can change perspective, playback speed, and camera mode after the fact.
• You can extract structured data (kills, damage, economy, positions) rather than just watching pixels.
• You can't edit the outcome or see anything the server didn't send to clients.

Demos come from two main sources: Valve's official matchmaking servers and third-party platforms that host their own matches.

Getting your demos onto your machine

The first practical hurdle is simply having the files. CS Demo Manager lists demos download as a feature — it can pull your last Valve or third-party demos for you, which avoids manually hunting through in-game menus or platform web pages.

If you'd rather do it by hand, the general flow is: finish a match, find the match in your game or platform's match history, and use its download option to save the .dem locally. Either way, you end up with files on disk that a manager can index.

What you can do once demos are loaded

CS Demo Manager's documented capabilities map to distinct jobs:

Finding a specific moment

The Search feature is aimed at exactly the moments players clip: 5K rounds, 4Ks, ninja defuses. Instead of scrubbing through a full match, you search the parsed data for the event and jump to it. This is the main reason to parse demos rather than just watch them.

Studying utility

The Grenades finder surfaces smokes and flashbangs from a demo. For a player reviewing their own utility usage or scouting an opponent's setups, this turns a 40-minute demo into a list of specific throws you can review.

Turning demos into visuals

Heatmap generation and export lets you see where players spent time or where events clustered, and Videos generation produces video output from demos — useful when you want to share a moment without sending someone a .dem file and a playback tool.

Getting data out

Export covers XLSX and JSON files, plus direct SQL queries against the database. If you want to build your own analysis, aggregate multiple matches, or feed numbers into a spreadsheet, this is the path — you're not locked into the app's own views.

Choosing whether this fits your workflow

CS Demo Manager is a companion application for Counter-Strike replays, so it's relevant if you already have .dem files or can download them and want more than in-game playback. It's less relevant if you only ever watch clips someone else already recorded.

The site provides Docs, a Download page, a Changelog, and a Blog, so you can check current behavior and requirements there before committing — those pages are the authoritative source for installation details and feature specifics, which can change between releases.
