The main Hookdeck alternatives are Svix, Webhook Relay, Convoy, and Hook0, plus building in-house. Hookdeck sells two products, Event Gateway for receiving webhooks and Outpost for sending them, so the right alternative depends on which one you use. Svix is the closest match for both: Svix Ingest replaces Event Gateway and Svix Dispatch replaces Outpost.
Hookdeck is a credible product. It says thousands of developers use it to handle billions of events, Outpost is Apache 2.0 open source, and its per-event prices are lower than Svix's pay-as-you-go rate. The common reasons to look at alternatives are wanting an uptime SLA without moving to a $499 plan, longer retention, PCI-DSS, or sending features like FIFO ordering, endpoint throttling, and payload transformations.
Below is each alternative with honest best-fit and poor-fit notes, Hookdeck's published pricing next to Svix's as of October 2026, and a short Svix vs Hookdeck comparison split into receiving and sending.
Replaces Event Gateway and Outpost
Svix covers both directions on one account: Svix Ingest for receiving webhooks and Svix Dispatch for sending them, and the free plan includes both. Ingest verifies signatures from providers like Stripe, GitHub, Shopify, and Slack out of the box, stores and retries failed deliveries, throttles traffic spikes, fans events out to multiple endpoints, and lets you filter, transform, and route them with JavaScript. Dispatch adds payload transformations, FIFO ordering, endpoint throttling, polling endpoints, an embeddable consumer portal, and SDKs in nine languages plus a CLI. Svix delivers billions of webhooks for fast-growing startups and the Fortune 500 with measured 99.99999% historical uptime. It's SOC 2 Type II audited and compliant with HIPAA, PCI-DSS, PIPEDA, GDPR, and CCPA. For local testing, Svix Play is free with no signup and forwards webhooks to your machine through the Svix CLI.
Best for: Teams that receive webhooks from providers and send webhooks to their own customers and want one vendor for both. Also the safer pick for regulated industries and for anything customer-facing where a missed webhook is a support ticket.
Not a good fit for: Teams optimizing only for the lowest per-event list price on a self-serve plan. Hookdeck's published per-event rates are lower than Svix's pay-as-you-go rate, though Svix's volume discounts narrow the gap at millions of messages a month.
See the Svix Ingest overview for receiving, and the full Svix Dispatch vs. Hookdeck Outpost comparison for sending.
Overlaps with Event Gateway
A long-running webhook tunneling and forwarding product from Webhook Relay (webhookrelay.com), a separate company unrelated to Svix, mostly used to route inbound webhooks to local environments and for small-scale fan-out. It sits closer to developer tooling than to a production webhook gateway.
Best for: Local development, internal tooling, and forwarding webhooks between systems where production reliability and compliance aren't requirements.
Not a good fit for: Regulated workloads, and sending webhooks to your own customers, which is the job Outpost does.
Alternative to Outpost
A source-available (Elastic License v2.0) webhook delivery server with a small hosted SaaS. It ships retries, replay, circuit breaking, and JavaScript transformations, but the company behind it essentially wound down and the project is now a side project, with measured uptime below 99.0% over the last 12 months.
Best for: Hobbyist self-hosting where you're comfortable maintaining the project yourself.
Not a good fit for: Production workloads. Without full-time maintenance, FIFO, or endpoint throttling, and with a source-available license, Convoy is a riskier choice than Outpost for most teams.

Alternative to Outpost
A small bootstrapped European startup offering webhook-sending infrastructure, with a hosted SaaS in the EU and a source-available SSPL self-hosted server. Hook0 covers subscriptions, retries, signatures, and replay, but only delivers HTTPS webhooks and lacks SOC 2, HIPAA, and PCI-DSS certifications.
Best for: Small EU teams with modest webhook volume that need EU-only data residency and don't need advanced features.
Not a good fit for: Multi-region data residency, queue or object-store destinations, regulated industries, or anything beyond a few thousand events per day.

Replaces either
Running your own receiving endpoint and delivery workers on top of a queue. If your requirements are genuinely unusual, this can be the right call. Several of the options above (Svix included) can be self-hosted (Svix's MIT-licensed open-source server), so it's usually worth starting from one of those before going fully in-house.
Best for: Teams with non-standard requirements and the engineering bandwidth to maintain webhook infrastructure long-term.
Not a good fit for: Most teams. Retries, signature verification, noisy-neighbor isolation, observability, replay, and a customer-facing portal are the long tail that eats engineering time.

Hookdeck prices Event Gateway and Outpost separately. Svix prices Dispatch and Ingest the same way, on one set of plans. Everything below is the public list price on Hookdeck's Event Gateway pricing, Hookdeck's Outpost pricing, and Svix pricing as of October 2026. Prices change, so check those pages before you decide.
| Plan | Price | Included usage | Retention | Uptime SLA |
|---|---|---|---|---|
| Developer | Free | 10,000 events a month | 3 days | None |
| Team | From $39 a month | 10,000 events a month, then pay as you go | 7 days | None |
| Growth | From $499 a month | 10,000 events a month, then pay as you go | 30 days | 99.999% |
| Enterprise | Custom | Custom | Custom | Custom |
Events beyond the included 10,000 cost $3.00 per 100,000 up to 5 million a month, dropping in steps to $0.35 per 100,000 above 500 million. Each destination includes 5 events per second, and more throughput is billed per event per second, starting at $3.00. A static IP is a $100 add-on, and HIPAA and SSO start on Growth.
| Plan | Price | Included usage | Retention | Uptime SLA |
|---|---|---|---|---|
| Starter | Pay as you go | First 50,000 events free, then $10 per million | 7 days | None |
| Growth | From $499 a month plus usage | 50,000 events, then $10 per million | 30 days | 99.99% |
| Enterprise | Custom | Custom | Custom | 99.999% |
Self-hosting Outpost is free under Apache 2.0. On the managed plans, usage is billed per event delivered and retries aren't charged. Hookdeck lists throughput as uncapped on every managed plan. A static IP is a $100 add-on, Starter is hosted in the US only, and Growth adds the EU and Asia, SSO, and HIPAA.
| Plan | Price | Included usage | Retention | Uptime SLA |
|---|---|---|---|---|
| Free | Free | 50,000 messages a month | 7 days | None |
| Basic | $20 a month | 50,000 messages a month, then $0.0001 each | 30 days | 99.9% |
| Professional | $490 a month | 50,000 messages a month, then $0.0001 each | 90 days | 99.99% |
| Enterprise | Custom | Custom, with volume discounts | Custom | 99.999% |
Messages beyond the included 50,000 cost $0.0001 each, or $10 per 100,000. Plans include 50, 200, and 800 messages per second, and Enterprise is custom. Only attempted messages count, so filtered messages and retries are free. Static source IPs come with Professional, and SSO and HIPAA with a BAA come with Enterprise.
On per-event list price, Hookdeck is cheaper. Outpost charges a tenth of Svix's pay-as-you-go rate, and Event Gateway under a third of it at its first volume tier. Svix's Enterprise volume discounts bring per-message pricing closer at millions of messages a month, but on self-serve plans at high volume, Hookdeck will cost less.
Svix is cheaper to start with an SLA. Basic is $20 a month with a 99.9% uptime SLA, 200 messages per second, and 30-day retention. Event Gateway's Team plan is $39 a month with no SLA and 7-day retention, and neither Hookdeck product includes an uptime SLA below $499 a month. The free tiers differ too: Svix includes 50,000 messages a month across Dispatch and Ingest, Event Gateway includes 10,000 events, and Outpost's first 50,000 events are free.
Packaging cuts both ways. Hookdeck includes SSO and HIPAA from Growth, where Svix puts them on Enterprise. Svix includes static source IPs on Professional, where Hookdeck sells them as a $100 add-on.
Hookdeck and Svix each sell a product for both directions, so it's more useful to compare them in pairs. Across both, Svix has measured 99.99999% historical uptime delivering billions of webhooks, and is PCI-DSS compliant on top of the SOC 2 Type II audits and HIPAA, GDPR, CCPA, and PIPEDA compliance that both companies list.
Both are managed gateways that sit between webhook providers and your code. Each verifies signatures for common providers like Stripe, GitHub, and Shopify, retries failed deliveries, fans events out to multiple destinations, and runs your JavaScript to filter, transform, and route them. Hookdeck also lists deduplication, Terraform support, and a CLI destination for local development. Svix Ingest offers a polling endpoint for receiving behind a firewall (Hookdeck's docs list HTTP, CLI, and Mock API as its destination types), and Svix covers local testing with Svix Play and the Svix CLI.
The bigger differences are in the plans. Svix keeps payloads for 7, 30, or 90 days depending on plan, against Event Gateway's 3, 7, or 30, and Svix's uptime SLA starts on the $20 Basic plan, while Event Gateway's starts on Growth at $499 a month. Read more about Svix Ingest.
Outpost is Apache 2.0 open source and runs managed or self-hosted from the same codebase. It covers retries, topics, multi-tenant isolation, an embeddable tenant portal, OpenTelemetry metrics, and destinations from HTTP to Kafka, SQS, EventBridge, and Pub/Sub. Hookdeck's docs say Outpost leaves out extras like per-tenant delivery rates by design, and point to Event Gateway, one of Outpost's destinations, for transformations and throughput control. Svix Dispatch builds payload transformations, endpoint throttling, and FIFO ordering (which Outpost's docs don't mention) into the sending product itself. Outpost's official SDKs cover TypeScript, Go, and Python, against nine languages plus a CLI for Svix. On price, Outpost's $10 per million events is a tenth of Svix's pay-as-you-go rate.

Pick Hookdeck if per-event price is your main constraint and you can go without an uptime SLA until you reach the $499 Growth plan. Outpost is a good fit if you want an Apache 2.0 server you can self-host with the same code Hookdeck runs. And if you need HIPAA or SSO without moving to an enterprise plan, Hookdeck includes both on Growth, where Svix puts them on Enterprise.
Pick Svix if webhooks are part of what your customers pay for, if you want an uptime SLA on a small budget, if you need PCI-DSS, or if your sending side needs FIFO ordering, endpoint throttling, payload transformations, or polling endpoints. It's also the simpler setup when you both receive and send webhooks, since one account covers Ingest and Dispatch. Brex, Clerk, Twilio, PagerDuty, Lob, Resend, Replicate, Lithic, Benchling, Drata, incident.io, and many others run their webhooks on Svix. If you prefer to self-host, Svix's MIT-licensed open-source server is a place to start.
