## Where the opening is

*Model estimate*

- The signals do not show a strong player focused on delivery observability for end users: recent deliveries, response bodies, redelivery, and status views are repeatedly requested, but the common products here are mostly delivery engines or SDKs.
  - [Track and monitor webhook delivery](https://github.com/graphql-hive/console/issues/5591) `githubissues` — 2024-09-06
  - [GitHub App Webhook Deliveries support](https://github.com/hub4j/github-api/issues/1404) `githubissues` — 2022-03-15
  - [Add a tab to view all deliveries processed under a webhook](https://github.com/netbox-community/netbox/issues/11360) `githubissues` — 2023-01-02
  - [Webhook Deliveries Logs: show user endpoint response](https://github.com/polarsource/polar/issues/3916) `githubissues` — 2024-09-06
  - [View of webhook deliveries](https://github.com/outline/outline/issues/3702) `githubissues` — 2022-06-29
- The search also suggests a gap in policy-aware outbound delivery with strong controls like retries, signing, dedupe, and per-endpoint visibility in one place; those features appear scattered across projects rather than packaged as the core product.
  - [npm: @voyant-travel/webhook-delivery](https://www.npmjs.com/package/@voyant-travel/webhook-delivery) `registries` — 2026-07-31
  - [npm: convex-webhook-sender](https://www.npmjs.com/package/convex-webhook-sender) `registries` — 2026-03-09

  - [webhookrelay/webhookrelay-go](https://github.com/webhookrelay/webhookrelay-go) `github` — 2020-06-09
- I do not see evidence of a dominant product that combines webhook delivery hosting with a polished customer portal for debugging and support workflows.

## What could go wrong

*Model estimate*

- Competition is real: smee.io, gosmee, Convoy, and Svix already cover parts of webhook sending, retries, and delivery infrastructure.
  - [probot/smee.io](https://github.com/probot/smee.io) `github` — 2019-03-31
  - [chmouel/gosmee](https://github.com/chmouel/gosmee) `github` — 2022-04-19
  - [Show HN: Svix – Open-Source Webhooks Service Written in Rust](https://news.ycombinator.com/item?id=30347858) `hackernews` — 2022-02-15

- A generic webhook delivery service can become a commodity unless it clearly wins on debugging, customer-facing delivery history, or policy controls.

  - [View of webhook deliveries](https://github.com/outline/outline/issues/3702) `githubissues` — 2022-06-29
- Security is a live risk area because webhook secrets and bearer tokens have been called out in recent complaints and HN posts.

## What to do this week

*Model estimate*

- Start with a narrow product: webhook delivery logs, retry controls, redelivery, and endpoint response visibility for teams that already send webhooks.
  - [Track and monitor webhook delivery](https://github.com/graphql-hive/console/issues/5591) `githubissues` — 2024-09-06
  - [GitHub App Webhook Deliveries support](https://github.com/hub4j/github-api/issues/1404) `githubissues` — 2022-03-15

  - [View of webhook deliveries](https://github.com/outline/outline/issues/3702) `githubissues` — 2022-06-29
- Make the customer-facing portal the wedge, not the delivery engine; the delivery engine can be straightforward, but the debugging workflow seems undersupplied.

  - [View of webhook deliveries](https://github.com/outline/outline/issues/3702) `githubissues` — 2022-06-29
- Bake in signing, dedupe, rate limiting, and alerting from day one because those are recurring pain points in the discussion signals.
