What is 21st.dev?
21st.dev is a portfolio builder for developers, integrates with GitHub, creates shareable project pages, supports custom domains and publishing, offers free and paid plans.
What is 21st.dev
A developer’s shortcut to modern software sanity. It’s a compact, opinionated guide that turns the chaotic stack-of-stacks into a practical checklist: security basics, shipping rituals, observability, docs, and the boring but essential chores. You get clear guidance and tool pointers, not hand-wavy platitudes.
Why it matters
Most teams relearn the same lessons at 2 a.m. after an outage. 21st.dev codifies “the obvious” before it bites you. It favors defaults that work over novelty for novelty’s sake—and trades framework FOMO for operational clarity.
How it works
No lock-in, no framework. It curates practices and links to proven tooling so you can assemble what fits your stack. Use it as a readiness checklist, a review rubric, or a starting point for a new repo. Less ceremony, more shipping.
Who it’s for
Small teams, indie hackers, and pragmatic seniors who want reliable apps without turning process into a full-time job. If you like receipts over hype, start here.
