CLUSTER MOCK-API-ENDPOINTS · 21 ENTRIES · EARLIEST ENTRY 2025-11-06
API testing and management tools
This cluster comprises web-based and desktop tools for building, testing, and managing HTTP and WebSocket APIs, including request builders, collection organizers, environment managers, and prompt-engineering workspaces. Dated entries before the index start show an initial grouping from November 2025 through January 2026, followed by a single entry in July 2026. PostmanLite leads traction with 11 stars, ahead of OpenBox and ericaqa-api-runner.
Entry timeline
ENTRY TIMELINE
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.
