Show HN: Mock endpoints with Polo
Polo is a no-account tool for mocking HTTP endpoints, with fake data generation, request logging, and data repetition built in.
Polo, a lightweight tool for mocking HTTP endpoints, launched publicly on August 20, 2026, per a Show HN post by its creator. The app is available at http-response.com and requires no account to use.
The tool targets developers building integrations and webhooks who need to simulate server responses without standing up a real backend. According to the HN submission, Polo includes fake data generation, data repetition, and request logging — the core features needed to replicate and inspect HTTP traffic during development and testing.
The project was posted by HN user primalscreamer, who described it as "a little app to make life easier when building integrations and webhooks." No company name, team size, funding, or founding date was disclosed in the submission. The source does not name a geographic location for the creator or project.
Mock endpoint and webhook testing tools occupy a well-used niche in developer tooling, alongside established products such as Mockoon, Webhook.site, and RequestBin. Polo's no-account-required approach positions it as a lower-friction option for quick, one-off testing scenarios rather than a full API mocking platform.
No pricing information, roadmap details, or expansion plans were included in the original post. The HN thread had no comments at the time of publication, leaving the project's reception and any community feedback still to come.
