Mittr

An API service that reliably delivers outbound actions such as webhooks and AI agent actions, solving the problem of silent failures, lost events, and lack of visibility in event delivery. It targets developers, ops, and IT teams at companies of all sizes, especially those building with AI agents. It is positioned as a drop-in reliability layer that handles retries, signing, dead-lettering, and audit trails, with a framework-agnostic approach that works alongside existing systems.

• HMAC signing for webhooks

• Full audit trail of all attempts
• Event persistence before delivery
• Dashboard for monitoring and recovery
