DevCompass

DevCompass is a library of developer learning paths that actually explains
things.

Ninety-six roadmaps cover the routes people genuinely take through this
industry: frontend, backend, DevOps, Android, iOS, data engineering, machine
learning, security, game development, engineering management and more. Each one
is broken into sections and topics, so you always know what comes next.

WHAT MAKES IT DIFFERENT

Most roadmaps hand you a diagram of boxes and leave you to search for each one.
Every topic in DevCompass has a written explanation — 4,964 of them, around
270,000 words in total. Each explains what the thing is in plain language, why
it earns a place in the path, and the mistake people actually make with it.
Many include a short code sample.

Nothing is generated on the fly. It was written to be read.

TRACK WHAT YOU KNOW

Tick topics off as you learn them. Every path shows your progress, and the
Explore screen picks up where you left off. Save the paths you care about and
come back to them.

WORKS OFFLINE

All content ships inside the app. Browse paths, read explanations and mark your
progress on a plane, on the underground, or anywhere with no signal. Only the
external resource links need a connection.

NO ACCOUNT, NO TRACKING

There is no sign-up and no server. Your progress is stored on your device and
never sent anywhere. No analytics, no usage tracking, no email address. Ads are
served by Google and are the only thing that sends data from your device — the
privacy policy sets out exactly what that means.

CURATED RESOURCES

Every section links to hand-picked documentation, articles, videos and courses —
1,390 of them, each checked to make sure it is still worth your time.

MADE FOR READING

Native, fast and built to platform conventions. Light and dark themes, or follow
your system setting. Dynamic Type support throughout.

HOW IT IS FREE

DevCompass is free and funded by ads. The introduction and first three sections
of every path open immediately. Later sections unlock one at a time by watching
a short video — always your choice, and once a section is open it stays open. An
occasional full-screen ad appears when you open the app.
