CLUSTER TESTING-WORKSPACES-API · 10 ENTRIES · EARLIEST ENTRY 2025-04-30

Collaborative API testing platforms

This cluster consists of web-based platforms for testing, documenting, and collaborating on APIs, supporting REST and WebSocket requests, collections, and team workspaces. The five dated entries are spread irregularly across months from December 2024 to March 2026, with no clear trend. ApiBolt leads on traction with 10 stars, while other members show no activity signal.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 10 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
