A keyless HTTP testing service with endpoints for inspecting requests and shaping responses, including status codes, headers, redirects, authentication, cookies, delays, and streams.

Landing page captured for the 2026-10-17 issue.

For: Developers testing HTTP clients and integrations
Worth noticing: The /drip endpoint can send bytes over time, with total duration limited to 10 seconds.

Field notes

The documented routes cover both request inspection and deliberate response shaping. Examples include method-specific echo endpoints, Basic and Bearer authentication checks, cookie helpers, compressed responses, and ETags. Some limits are explicit: random binary output is capped at 1 MiB, while delayed and drip responses are limited to 10 seconds.
