Many companies need reliable webhook delivery but don't want to depend on external services. A simple binary that routes events with Postgres backing would appeal to this market.
Create a single-binary application that receives, queues, and delivers webhooks with retry logic. Focus on minimal dependencies and easy deployment.
Offer commercial licenses for enterprise features like advanced logging. The open source core would drive adoption.
The MVP could handle basic HTTP delivery with PostgreSQL queueing. The risk is existing message brokers adding webhook-specific features.
