Showing the first 200 of 623 — ordered by how strong the evidence is, then by standing. Narrow it with a filter to see the rest.

APIs and SDKs — the short answers

Every number here comes from our own daily check — not from a vendor list.

APIs and SDKs — how many are there?: Tablif is tracking 623 of them. 602 answered our check today, and 14 we couldn't reach — we don't claim those are dead.
Which ones are still maintained?: Tablif knocks on every door once a day and records the answer. 602 of these 623 responded on the latest run, so that number is what "still here" means on this page — not a review score.
Are any of them free?: 94 of the live ones say so in their own words, and 27 let you start without making an account. Tablif records the claim the product makes; we don't verify pricing.
Any open-source options?: 62 of the live ones on Tablif mention being open source.
What's the newest one?: Image Automation API — Tablif first saw it today.
Did a person actually look at these?: 623 of them Tablif opened and read, then wrote a one-line summary in our own words instead of reusing the founder's tagline. The rest carry keyword labels we haven't confirmed by reading yet — and we say so rather than hiding it.
