The decision between Signalman and Webhook.site usually comes down to one question: do you need the breadth of features that Webhook.site offers, or would a focused tool that stays out of your way be a better fit? Webhook.site has spent years building an ecosystem around webhook debugger. Signalman does one thing well and gives you complete control of the underlying data.
Architecturally, Signalman and Webhook.site could not be more different. Webhook.site runs on distributed cloud infrastructure with load balancers, managed databases, CDNs, and redundancy across availability zones. Signalman is a single process writing to a single file on a single disk. That sounds fragile until you realize that SQLite handles more concurrent readers than most web applications will ever need, and WAL mode means reads never block writes.
Switching from Webhook.site to Signalman is straightforward for most teams. Export your data from Webhook.site (most services offer CSV or JSON export), then POST each record to Signalman's API. A migration script that reads the export and writes to /api/ endpoints typically takes less than 50 lines of code. The reverse migration is equally simple — Signalman's SQLite database is a standard file you can query with any SQLite client.
Single binary. Free to start. $0.99/mo for Pro.
