A curated directory

Developer tools,
worth the shelf space.

Auth, payments, email, UI, databases, hosting, monitoring, analytics and AI — hand-picked, with what each tool is actually for and where the catch is.

Nine shelves, 58 tools.

Each shelf is a page with the full list, what every tool runs on, and what it costs. Nothing here is ranked — a directory that pretends to rank is worse than one that admits it does not.

Tools from this side of the site.

The reason devtool.fyi exists. These are made and maintained byRenfred Alonge, and they sit in the categories above alongside everything else — no special treatment beyond this section.

Approach

How this list works.

01

Opinions, not listings

Every entry says what the tool is actually for and where the catch is. A directory that only repeats marketing copy saves nobody any time.

02

Small enough to trust

A curated set, not everything that exists. Shelves get added when there are enough good tools to fill one, not to pad the count.

03

Built to stay small

Static HTML, no tracking, no framework doing work it does not need to. Adding the next tool takes one entry in one file.

Contribute

Missing something?

The list grows when somebody says what is not on it. Suggesting a tool takes two minutes and readers vote on it; adding one yourself is a pull request touching one file; saying an entry has gone stale needs no account at all.

  • Suggest a toolTwo minutes, and other readers vote on it
  • Add one yourselfOne entry in one file, and it is on the shelf
  • Report an entryPrices change and links die — nothing notices on its own
