The tools
All 21 tools, from the webhook tester and signature generator to the Block Kit builder and flow designer, run in your browser. Text you paste, including tokens and payloads, is processed on your device and is not transmitted to this site.
Two exceptions happen only on your explicit action:
- The Send button in the Telegram API builder sends the request directly from your browser to
api.telegram.org. - The Discord embed and Slack Block Kit previews load images from URLs you type, directly from those hosts.
Your browser's local storage keeps your color theme, guide progress and the inputs of most tools so you can pick up where you left off. Secrets such as bot tokens and webhook secrets are never saved. Use the Reset button at the top of a tool, or clear site data in your browser, to remove it. None of it is sent to this site.
Hosting
The site is delivered by a content delivery network. Like any web server, it processes technical data such as IP addresses and request headers to deliver pages and protect against abuse. We do not use that data to profile visitors.
Changes
If this notice changes, the new version will be published on this page.
