Stubby offers a suite of four essential developer tools designed for immediate use without any signup. This integrated tab allows you to mock JSON endpoints, set up uptime monitors, inspect incoming webhooks, and track SSL certificate expiry.

• Mock Endpoints: Quickly generate stable public URLs for your mock JSON data. Customize status codes, headers, and delays.

• Uptime & SSL Monitoring: Schedule pings for any URL and monitor its TLS certificate status. Receive alerts for downtime and upcoming certificate expirations (30, 14, and 7 days prior).

• Webhook Inspector: Capture and analyze incoming HTTP requests in real-time, providing detailed insights into methods, headers, and bodies.

• Status Pages: Create and publish public uptime pages to display the status of your services.

• Alert Channels: Configure notifications via Email, Slack, Discord, and custom webhooks.

Stubby runs instantly upon opening, requiring no extensions or accounts for core functionality. A free tier offers robust features, with an optional Pro upgrade for persistent resources, increased limits, and advanced alerting. An account is only necessary for syncing data across devices.
