Get started with Pro →

For an individual developer returning to the same integrations. HTTP, email, and DNS share the event allowance. Stored data includes headers and encoded payloads. A request body can be up to 1048576 bytes.

Self-hosted

Free software. Your infrastructure costs.

The core stays MIT-licensed: capture, inspection, MCP, local forwarding, signature verification, and activity history. No Openhook account, license server, or hosted subscription is required.

You operate the server, configure its limits, and own backups and availability.

What happens at a limit?

New events receive an error. There are no automatic overage charges and no silent eviction to make room. Export or delete events to free storage; the monthly event counter resets at the start of each UTC calendar month.

What happens when paid access ends?

New events stop at the end of the paid period. Your inbox stays accessible for up to 30 more days before expiry; individual payloads still expire 30 days after receipt. Export anything you need before then.

What are you paying for?

Hosting, persistent endpoints, account access, and capacity. The open-source tools remain available to everyone. No uptime SLA is included in this initial plan.
