Is brew.fm Trustworthy and How Does It Access My Spotify Account?

brew.fm is a third-party Spotify companion tool that has been running since 2021 and, according to its own site, is used by 5,000+ people. You connect it by signing in with Spotify, which authorizes brew.fm to read the playlists in your library and write new playlists back into your Spotify account. The site reports activity such as 260 playlists updated in a week and 9,600+ tracks placed into listeners' Spotify, which is the kind of usage data you'd expect from an actively used service. For the specific terms of what brew.fm stores and how it handles your data, check the privacy documentation on brew.fm itself — that is the authoritative source, not a third-party summary.

What brew.fm actually does

brew.fm turns the artists already sitting in your playlists into a release watchlist, then drops their new releases into Spotify for you. The pitch is aimed at a specific gap: Spotify's Release Radar resets every Friday, so anything you miss that week is gone, and it only leans on artists you remembered to follow. brew.fm instead works from artists you've already collected in playlists, so you don't have to maintain a follow list or check in weekly.

How the Spotify connection works

The flow is a standard OAuth-style sign-in:

1. You choose Sign in with Spotify on brew.fm.
2. Spotify asks you to authorize brew.fm to access your account.
3. brew.fm reads the playlists you point it at and identifies the artists in them.
4. It creates a separate Spotify playlist and writes new releases into it.

The practical implication: brew.fm needs both read access (to see your playlists and their artists) and write access (to create and update playlists in your account). That's why the sign-in step is required rather than an email signup — there's no way to build a playlist in your Spotify without it.

Signals that it's a real, used service

These are self-reported figures from brew.fm's own page, so treat them as the company's claims rather than independently verified numbers. The Hacker News placement and the Reddit quote are the kind of third-party traces that suggest real people have tried it, but you can verify the Reddit thread and the HN post yourself if that matters to you.

What to check before you connect

Because you're granting playlist read/write access, a few things are worth confirming on brew.fm's own site before signing in:

• Privacy policy and data handling — what brew.fm stores, for how long, and whether it's shared. The site's own privacy documentation is the place to look; this article can't substitute for it.
• How to revoke access — Spotify lets you remove a connected app from your account settings, so you can disconnect brew.fm without deleting your Spotify account.
• What gets written — confirm whether brew.fm only creates new playlists or can also modify existing ones. The free tier creates a separate playlist; the paid Lifetime tier unlocks features that can add matching tracks to the source playlist itself, so if you don't want anything touching your original playlists, stay aware of which tier you're on.

Free vs. Lifetime, in access terms

• Free (Unroasted): watches the 10 most-represented artists in each source playlist and gathers their releases into a separate Spotify playlist. No card needed to start.
• Lifetime: watches every artist in the source playlist, checked daily, and unlocks Signature Blend and Drip, which can add matching tracks into the source playlist while trying to preserve its character.

The access you grant at sign-in is the same either way; the difference is how much of your library brew.fm processes and whether it writes into your existing playlists.

Bottom line

brew.fm is a plausible, actively used tool with a clear mechanism: Spotify sign-in grants it read access to your playlists and write access to create new ones, and it uses the artists you already have to catch releases you'd otherwise miss. The trust question comes down to two things you should verify directly on brew.fm — its privacy terms and how to revoke Spotify access — rather than relying on any summary, including this one.
