Free Developer Tools APIs — FAQ
Are there free Developer Tools APIs with no API key?
Yes — 103 of the 183 free developer tools APIs we list need no API key or signup (ipify is a good starting point). Use the "No key" filter above to see them; they're the fastest to prototype with.
Which free Developer Tools API is the most reliable?
Of the 32 developer tools APIs on our probe schedule, ipify leads on measured uptime (—% over 90 days). Reliability here is verified from our own scheduled checks, not the provider's claims — sort by "Reliable" to rank the rest.
Can I call these Developer Tools APIs from the browser?
111 of these developer tools APIs send CORS headers over HTTPS, so you can fetch them straight from front-end code — no backend proxy. Filter by "Browser OK" to see them; the rest need a server-side call.
Are these free Developer Tools APIs OK for commercial use?
1 of the 183 developer tools APIs allow commercial use on the free tier; the rest are unclear or personal-only. We record service terms and the data license as separate fields on every listing — check both before you ship.
How often are these Developer Tools APIs checked?
183 of the 183 developer tools APIs are on our probe schedule and re-tested every sweep. We log uptime, latency and response-shape changes on each, and move any that stay down to the graveyard so you can see what died and when.
