Best Webhook Tools in 2026 (Receiving, Sending, Debugging)

The best webhook debugging tool for most people is a free inspector: Webhook.site, Hookdeck Console or Svix Play gives you a URL and shows the raw request in seconds, and none of them needs an account to start. After debugging, webhook tools split into two more jobs. Receiving reliably (surviving retries, duplicates and your own downtime) is what Hookdeck's Event Gateway and Convoy do as a gateway in front of your endpoint. Sending webhooks to your own customers, with per-customer endpoints, signing, retry policy and a delivery log, is Svix's core product (and Hookdeck's newer Outpost). If the endpoint doing the receiving is an app you're building anyway, Greta generates it with verification, idempotency and a retry-safe handler included. Know which of the three jobs you have; buying for the wrong one is the usual mistake.

Webhooks look trivial until the first duplicate delivery charges a customer twice. Almost everything hard about them is delivery semantics, not HTTP.

How we compared

Which job each tool does, what it gives you for retries and replay, whether signature verification is handled or assumed, and cost at low volume. Prices and free-tier limits were checked on each vendor's own pricing page and docs on October 4, 2026, and are stated as of October 2026 with their billing basis. They change; check the vendor page before you budget.

At a glance

RequestBin, which used to sit in this table, is gone as a standalone tool: requestbin.com now redirects to Pipedream's homepage, and no Pipedream page describes it any more.

The three jobs

Debugging. You need to see what Stripe or Shopify actually posts. Webhook.site gives you a URL and shows the request (headers, body, timing) with no account; a free URL takes 50 requests and expires after seven days. Hookdeck Console does the same with "no setup and no signup", and pairs with the free Hookdeck CLI to forward the captured request to code on your laptop. Svix Play is the third free option. Most webhook confusion ends here, for free. Reach for ngrok when you want a public URL for a local server more generally: its Traffic Inspector can replay a captured request, and its Verify Webhook action checks signatures before your code sees the request.

Receiving reliably. This is where money gets spent and where it is often justified. Providers retry on non-2xx, which means your five minutes of downtime becomes a burst of duplicates later. A gateway like Hookdeck or Convoy accepts the delivery immediately, queues it, retries against your endpoint on your terms, and lets you replay a range after you ship the fix. That last capability, replay, is the one teams discover they needed after an outage.

Sending to your own customers. Being a webhook provider is a product surface: per-customer endpoints, secret rotation, signature schemes, exponential backoff, a delivery log customers can self-serve, and a dashboard when they ask why event 41 never arrived. Svix sells exactly that; Convoy self-hosts it; Hookdeck now has Outpost, an Apache 2.0 sending service. Building it yourself is a quarter of work that looks like two weeks.

Hookdeck vs Webhook.site for testing

For pure inspection they overlap: both hand you a URL and show what arrived. The differences are what happens next.

• Account and limits. Webhook.site's free URL stops after 50 requests and expires after seven days; the paid plans remove both (Basic is $9 a month or $90 a year). Hookdeck Console needs no account, and Hookdeck's free Developer plan covers 10,000 events a month if you move on to the gateway.
• Getting the request to your laptop. Webhook.site's localhost forwarding (its whcli CLI) is listed as a paid feature. Hookdeck's CLI (hookdeck listen <port>) is free, and Hookdeck describes it, used with Console, as a free alternative to ngrok.
• Where it leads. Webhook.site stays a debugging and automation tool (paid plans add forwarding, transforms and Custom Actions). Hookdeck's Console is the front door to a production gateway, so the same tool can later sit in front of your real endpoint.

If you only need to see one payload today, use whichever is open in your browser. If you expect to keep debugging the same integration, Hookdeck's free CLI forwarding is the practical difference.

Is Hookdeck good for webhook debugging and testing?

Yes, and the debugging side is free: Console captures requests with no account, the CLI forwards them to a local port, and you can replay a captured request while you iterate. Its real strength is what comes after testing. The Event Gateway retries failed deliveries automatically (up to 50 automatic retries per event, plus unlimited manual retries), supports bulk retry from the dashboard or API, and Hookdeck's pricing page says "the price of an event includes all its retries".

Is Hookdeck good for startups?

For a startup receiving webhooks from Stripe, Shopify or GitHub, the free Developer plan (10,000 events a month, 3-day retention, one user, no credit card) is enough to put a gateway in front of a low-volume app. The Team plan starts at $39 a month with pay-as-you-go usage, 7-day retention and unlimited users. Hookdeck's pricing page states its per-event overage rate in more than one way, so model your expected volume in its calculator rather than trusting a single per-100k figure. The question to ask is not price but need: if a missed or duplicated event would cost you money and you have no way to replay it, a gateway earns its place early.

Hookdeck vs Svix

They started on opposite sides of the same pipe, and both vendors describe it that way. Hookdeck began with receiving (inbound webhooks from other services) and added Outpost for sending. Svix began with sending (webhooks your product delivers to your customers) and added Svix Ingest for receiving. Each vendor's comparison pages call the other's crossover product the newer one; treat those pages as marketing, but the split is a useful rule of thumb.

• You consume webhooks from Stripe, GitHub or Shopify and want queueing, retries and replay: start with Hookdeck's Event Gateway.
• Your product sends webhooks to customers and needs a customer-facing portal, per-endpoint secrets and a delivery log: start with Svix (free up to 50k messages a month, Basic from $20 a month, $0.0001 per message beyond 50k).

Replay: Hookdeck compared with Svix

On Hookdeck, a failed event can be retried manually as many times as you like, in bulk from the dashboard or through the API, and replaying a request "re-ingests the original request" through the full pipeline as a new request. On Svix, retries follow a fixed schedule (immediately, then 5 seconds, 5 minutes, 30 minutes, 2 hours, 5 hours, 10 hours and 10 hours), and your customers can, from the Svix application portal, resend a single message, "Recover Failed" messages from a given date, or "Replay Missing" messages that were never attempted to an endpoint. Hookdeck's replay is built for the receiver fixing its own outage; Svix's is built for the sender's customers fixing theirs.

What is the best webhook gateway?

If you receive webhooks, Hookdeck's Event Gateway is the managed option with a usable free tier. If you want to run the gateway yourself, Convoy handles incoming and outgoing webhooks in one self-hosted service; its latest release (v26.8.0) shipped on September 28, 2026, and it is source-available under the Elastic License 2.0 (which bars offering it as a hosted service) rather than OSI open source. If you send webhooks, Svix is the established managed choice.

What no gateway does for you

Whatever you buy, the receiving endpoint still has to be correct, and the correctness lives in three rules: verify the signature before parsing the body (and use the raw bytes, because JSON re-serialisation breaks the HMAC), make the handler idempotent on the provider's event id, because duplicates are normal and not an error, and return 2xx fast, doing the real work after acknowledging. A gateway in front of a handler that fails any of the three just delivers the same bug more reliably. The classic place this bites is billing: if your app learns about renewals from a subscription billing tool's webhooks, a non-idempotent handler is how one renewal turns into two credits or two receipts.

If that endpoint belongs to an app you are building rather than a service you already run, describing it to Greta generates the handler with those rules applied: verification, an idempotency key on the event id, and the queue-then-acknowledge shape, deployed with the rest of the app. The free tier is 5 credits a day; Starter is a $5/month welcome offer (normally $20/month). Our webhooks and third-party APIs guide covers the same ground for apps already in flight, and the duplicate-webhook test is the check worth running before launch. When a webhook handler does throw in production, an error tracking tool is what tells you which event broke it.

Plainly: Greta is not a webhook gateway. If you need replay across a large history of deliveries, buy Hookdeck or run Convoy. And if the job is moving data between SaaS tools rather than handling raw webhooks, an integration platform may be the better fit.

FAQ

What is the best webhook testing tool? For seeing a payload immediately, Webhook.site, Hookdeck Console or Svix Play; none of them needs an account to start. Add the Hookdeck CLI (free) or ngrok when the request needs to reach your local machine. None of these debugging tools is meant to sit in production.

What are some tools like Webhook.site for testing webhooks? Hookdeck Console (no account, pairs with a free CLI for localhost forwarding), Svix Play (free, no signup), and ngrok's Traffic Inspector when you are already tunnelling to localhost. RequestBin is no longer available as a standalone tool; its domain now redirects to Pipedream.

Is Hookdeck good for webhook debugging and testing? Yes. Console and the CLI are free for debugging, and the same account carries into the Event Gateway, whose free Developer plan covers 10,000 events a month with retries and replay included.

Hookdeck vs Svix: which do I need? Hookdeck if you receive webhooks and want queueing, retries and replay in front of your endpoint. Svix if your product sends webhooks to customers and you want a managed delivery service with a customer-facing portal. Each now offers the other direction (Hookdeck Outpost, Svix Ingest), but those are the newer products on each side.

What are Hookdeck's replay capabilities compared to Svix? Hookdeck lets you retry failed events manually without limit, in bulk or by API, and replay any request through the full pipeline. Svix retries on a fixed schedule and lets your customers resend a message, recover all failed messages since a date, or replay messages never attempted to an endpoint.

Do I need a webhook gateway? If duplicate or missed deliveries would cost money, and you have no way to replay them after an outage, yes. If you receive a handful of low-stakes events, a correct handler is enough.

How do I stop duplicate webhook deliveries causing double charges? You do not stop the duplicates; providers retry by design. You make the handler idempotent: store the provider's event id and make replaying it a no-op.

Should I build my own webhook sending infrastructure? Only if webhooks are a differentiated part of your product. Signing, retries, per-customer secrets, delivery logs and a debugging surface add up to far more than the send loop implies; Svix, Hookdeck Outpost and Convoy exist because that quarter is real.
