Triggerman

Automate your browser with custom triggers that react to what any website does the moment you visit them.

What can you do with it? - Automatic redirects: Seamlessly redirect to fallback or mirror sites when a page fails to load or returns a 4xx/5xx error. No more dead ends. - Webhook automation: Fire HTTP requests to Slack, Discord, or your own APIs whenever a specific page loads, an API returns a certain status code, or a connection succeeds or fails. - Failure detection: Get instant reactions to DNS errors, timeouts, and connection drops. Perfect for monitoring dev environments or critical services. - Flexible URL matching: Use regex capture groups to build dynamic, adaptive rules. Match a URL pattern once and handle dozens of paths automatically. Why Triggerman? Triggerman leverages Chrome's native webRequest API to detect events the instant they happen, with response times measured in milliseconds. Whether you're a developer monitoring a local server, a DevOps engineer triggering incident alerts on 5xx errors, or a power user who wants reliable fallbacks, Triggerman gives you full control with a simple, visual rule editor. Privacy-first. Your rules stay private. Stored locally and synced only across your own devices if so desired. No telemetry, no analytics, no data collection. The only network requests Triggerman makes are the webhooks you explicitly configure. Get started in seconds: Install the extension, create a rule, pick your trigger and action, and you're done. Rules activate instantly across all tabs.
