Hooksbase is an alternative to Hookdeck and Svix, built for teams whose consumer is an AI agent. Where most webhook tools are HTTP-to-HTTP, Hooksbase adds email, form, and scheduled-cron ingest, plus typed outbound delivery to AWS SQS, AWS EventBridge, GCP Pub/Sub, and S3 alongside HTTP. Every delivery gets retries, strict FIFO ordering, a dead-letter queue, and deterministic replay from persisted snapshots. Five verified provider packs (Stripe, GitHub, Clerk, Slack, Resend) validate signatures on the way in; outbound signing is Standard Webhooks-compatible. It runs entirely on Cloudflare's edge and is hosted-only, with flat, predictable tiers โ Free (5,000 deliveries/month, no card), Starter $25, Pro $79, Business $249 โ instead of per-event metering.

HooksbaseHooksbase's answer:
Most webhook tools are HTTP-in, HTTP-out. Hooksbase ingests events over four channels โ HTTP webhooks, email, hosted forms, and scheduled cron โ and delivers to typed destinations beyond HTTP: AWS SQS, AWS EventBridge, GCP Pub/Sub, and S3-compatible storage. Every delivery is persisted with deterministic replay, so a consumer that was down โ often an AI agent โ can recover exactly the events it missed. It runs entirely on Cloudflare's edge and pricing is flat per tier rather than metered per event.
Hooksbase's answer:
Choose Hooksbase if your event consumer is an AI agent or you need more than HTTP-to-HTTP. Compared to Hookdeck and Svix, it adds email, form, and scheduled-cron ingest plus typed delivery to AWS SQS, EventBridge, GCP Pub/Sub, and S3 โ with retries, strict FIFO ordering, a dead-letter queue, and deterministic replay from persisted snapshots on every delivery. Signature verification is built in for Stripe, GitHub, Clerk, Slack, and Resend, and outbound signing is Standard Webhooks-compatible. Tiers are flat and predictable โ Free (5,000 deliveries/month, no card), then $25/$79/$249 โ instead of per-event metering.
Hooksbase's answer:
Developers building AI agents and automations that consume external events, and small teams that want reliable webhook ingest, routing, and delivery without running their own retry and replay infrastructure. Typical users receive events from providers like Stripe, GitHub, Clerk, Slack, or Resend and need them delivered โ in order, with recovery โ to an agent, an HTTP endpoint, or a cloud queue.
Hooksbase's answer:
Hooksbase came out of rebuilding the same webhook plumbing โ ingest, verify, retry, replay โ for every agent project. Instead of rebuilding it again, we made it a hosted service on Cloudflare's edge, with the multi-channel ingest and deterministic replay agents actually need.
Hooksbase's answer:
Hooksbase runs entirely on Cloudflare: Workers for compute, D1 for state, R2 for payload storage, Durable Objects for delivery ordering and rate limiting, and Queues for fan-out. The API is built with Hono in TypeScript, and it ships a first-party TypeScript SDK and CLI.

There are several strategies to solve this kind of challenge, but today we will see MockServer as a tool to resolve it. - Source: dev.to / almost 2 years ago
The open-source examples are mockoon, mock-server.com, etc. Source: about 3 years ago
I've just found out MockServer and it looks awesome ๐คฉ so I wanted to check it out repeating the steps of my previous demo WireMock Testing which (as you can expect) uses WireMock, another fantastic tool to mock APIs. - Source: dev.to / about 4 years ago
I tend to use MockServer. With MockServer you can define inputs, so you can say that the request should look like this with that URL, etc etc. That way you can verify that the request looks okay. Source: over 4 years ago
