Legal

Terms of Service

Last updated July 9, 2026

Redline is a free tool. These terms are short on purpose — using the service means you agree to them.

The service

Redline provides two tools: an API request tester that proxies HTTP requests on your behalf, and a webhook debugger that captures requests sent to a disposable inbox URL. Both are provided "as is," free of charge, with no account required.

Acceptable use

You agree not to use Redline to:

  • Attack, scan, flood, or otherwise abuse a third-party endpoint or Redline itself.
  • Attempt to reach internal/private infrastructure through the proxy (this is also blocked technically — see the Security Policy).
  • Send or store unlawful content through a webhook inbox.
  • Interfere with the availability of the service for other users.

We reserve the right to rate-limit, block, or remove access for use that threatens the service or third parties.

Your responsibility for data you send

You are responsible for what you choose to send through the API Tester and what you allow to be sent to a Webhook Debugger inbox — including any credentials, tokens, or personal data contained in that traffic. Redline is a debugging tool, not a secrets vault; don't rely on it to store anything long-term or highly sensitive.

No warranty

Redline is provided without warranties of any kind, express or implied, including fitness for a particular purpose or non-infringement. We don't guarantee uptime, that responses proxied through the API Tester are accurate or unmodified in transit, or that webhook data will never be lost.

Limitation of liability

To the fullest extent permitted by law, Redline and its operator aren't liable for any indirect, incidental, or consequential damages arising from your use of the service, including data loss or exposure of information you chose to send through it.

Changes

The service and these terms may change as Redline evolves. Material changes will be reflected on this page with an updated date.
