What Is SharePad.io and What Is It Used For?

SharePad.io is a free online code interview tool built around a real-time collaborative code editor with built-in compilers, so an interviewer and a candidate can write and run code together in the browser. It fits situations where two or more people need to see the same code as it is typed and execute it without setting up local environments — most commonly technical interviews, paired coding screens, and ad-hoc shared coding sessions.

Core capabilities

Based on the site's own description, the product centers on three things:

• Real-time collaborative editing — multiple participants work in the same editor view, so changes appear for everyone as they happen rather than through copy-paste or screen sharing alone.
• Built-in compilers — code can be run inside the tool, which means the interview does not depend on the candidate's machine having the right runtime installed.
• Free access — the site presents itself as a free tool; no pricing page or paid tiers are indicated in the available material.

What it is typically used for

Technical interviews

The primary use case. An interviewer shares a session, poses a problem, and watches the candidate's approach develop in real time. Because the editor is shared, the interviewer can type hints or corrections directly into the same buffer instead of describing them verbally.

Shared coding sessions

Pair programming, mentoring, or debugging with a colleague. The combination of a shared buffer and an in-browser runner removes the usual friction of "can you see my screen?" and "do you have Node/Python installed?"

Practice and walkthroughs

A candidate or learner can use the environment to work through problems while someone else observes and comments, which is useful for mock interviews.

How a session typically works

1. One person opens SharePad.io and starts a session, which produces a shared editor view.
2. The other participant joins that session, so both see the same code.
3. Either side writes or edits code; changes propagate in real time.
4. Code is executed using the built-in compiler, and the output is visible to both participants.
5. The session continues as a discussion of the code and its output.

The exact menu labels and sharing mechanics are not documented in the available material, so treat the steps above as the general flow rather than a click-by-click guide.

Where it fits and where it doesn't

Practical considerations before adopting it

• Confirm language support first. Since the available material does not enumerate compilers, check that the languages your interviews use are runnable before standardizing on the tool.
• Test the collaboration under real conditions. Run a short mock session with a colleague on the same network conditions your candidates will have, and note any lag in the shared editor.
• Have a fallback. For interviews where a specific IDE, debugger, or repository access matters, a browser editor with a built-in runner may not be sufficient; decide in advance what you will do if the session fails.
• Check data handling if you handle sensitive material. The available material does not describe retention or privacy practices, so verify those directly on the site if interview content is confidential.

For teams that just need a shared editor plus a way to run code during a conversation, SharePad.io covers that narrow but common need without installation. For anything involving recorded assessment, structured scoring, or heavy project-based tasks, look for a dedicated platform instead.
