Hookdeck Event Gateway vs Svix Ingest: Webhook Receiving Compared
Managing a few webhooks is simple. But as you add more, you need to start thinking about queuing, routing, and retry mechanisms to give you the certainty you need to rely on them. Hookdeck's Event Gateway ensures you can ingest and act on inbound webhooks without setting up custom infrastructure.
If you're evaluating infrastructure for receiving inbound webhooks, Hookdeck's Event Gateway and Svix Ingest are two products worth comparing. Both handle incoming webhooks, but they approach the problem differently: Event Gateway is a purpose-built inbound webhook platform with deep queueing, filtering, and observability, while Svix Ingest is a newer addition to Svix's primarily outbound-focused webhook platform.
This comparison breaks down the meaningful differences across every major capability area so you can make an informed decision.

The Event Gateway approach
Before diving into individual features, it's worth understanding the product philosophy behind Event Gateway. Event Gateway is an all-in-one tool for managing inbound webhooks at scale, without managing custom infrastructure yourself. Its feature set is broad, but in-depth. When inbound webhooks are critical for your team, Event Gateway provides the infrastructure and tooling to make them reliable and manageable. With it, you can handle:
- Receiving webhooks: Ingesting webhooks from a source, like Shopify, Stripe, or Twilio, shouldn't require extensive integration work. Instead, you should be able to consume events using light-touch, standards-based methods like webhooks.
- Delivering webhooks: Similarly, getting your events to a customer's destination should be easy to set up without the need for complex integrations.
- Filtering webhooks: Process only the webhooks that meet the metadata and payload criteria you've set.
- Transforming webhooks: Transform webhooks to be compatible with destination systems.
- Retries and rerouting: When a destination is temporarily unavailable, retry webhook delivery automatically so you don't have to build that logic into your application.
- Scaling to meet demand: Automatically adjust to the ebb and flow of demand.
- Security and compliance: Authenticate and authorize sources and destinations.
- Operational visibility: Provide end-to-end insights into what's happening at the system level and the individual webhook level. With comprehensive tools to help you act, not just observe, when things go wrong.
Pre-configured webhook sources
Getting started with a new webhook provider typically means reading their docs, figuring out the auth mechanism, configuring signature verification, and handling their specific response format. Pre-configured sources automate this.
Hookdeck Event Gateway ships with over 120 pre-configured source types. Each source auto-configures authentication, signature verification, and response formatting for that specific provider. You select the provider, and Event Gateway handles the rest.
Svix Ingest offers 30+ pre-configured sources, available on Professional plans and above. Free tier users need to configure sources manually.
The practical difference is setup time. If you're integrating with providers like Stripe, Shopify, GitHub, Twilio, or any of the other 100+ sources Event Gateway supports out of the box, you skip the manual configuration entirely.
Queueing and backpressure
This is one of the most fundamental architectural differences between the two products.
Hookdeck Event Gateway includes a built-in durable event queue with backpressure handling. When your downstream services are slow or unavailable, Event Gateway buffers incoming webhooks and delivers them at a pace your infrastructure can handle. During traffic spikes, the queue absorbs the burst rather than forwarding it and overwhelming your services.
Svix Ingest doesn't expose a queue to end-users. It offers configurable rate limiting, which can throttle delivery, but there's no durable buffer sitting between the incoming webhooks and your endpoints.
This matters most during outages and traffic spikes. Without a queueing layer, a sudden burst of webhooks either hits your services all at once or gets dropped. With Event Gateway's queue, those webhooks are held and delivered when your services are ready.
Filtering
Hookdeck Event Gateway provides advanced conditional logic with filter rules on any payload field. You can drop, route, or flag events based on their content before they ever reach your services. This is useful for reducing noise — for example, ignoring certain event types from a provider, or routing events to different endpoints based on payload content.
Svix Ingest does not offer filtering capabilities. Every incoming webhook is forwarded to your configured endpoints without the ability to conditionally process or discard events at the infrastructure level.
If you're receiving high volumes of webhooks where only a subset are relevant, filtering at the infrastructure layer saves you from processing (and paying for) events your services don't need.
Deduplication
Duplicate webhook deliveries are common: providers retry on timeouts, network issues cause duplicates, and some providers send the same event multiple times by design.
Hookdeck Event Gateway provides both exact deduplication (matching on the full payload) and field-based deduplication (matching on specific fields like an event ID). Duplicates are caught and dropped before they reach your services.
Svix Ingest does not offer deduplication. Your application is responsible for handling duplicates, which means building and maintaining idempotency logic in your own code.
Infrastructure-level deduplication removes an entire class of bugs and simplifies your application logic, particularly at high volumes where duplicate rates tend to increase.
Routing
Both products support routing webhooks to multiple destinations, but the depth of routing logic differs significantly.
Hookdeck Event Gateway offers dynamic routing with connection rules, fan-out to multiple destinations, and the ability to multiplex sources across multiple destinations. Routing rules can be combined with filtering and transformation, so you can conditionally route events based on payload content, headers, or source.
Svix Ingest supports multi-endpoint fanout with JavaScript-based routing logic, available on Professional plans and above. This gives you programmatic control over routing decisions, but requires writing and maintaining JS functions.
Event Gateway's declarative routing rules can be configured without code, while Svix's approach requires JavaScript for anything beyond basic fanout.
Transformations
Hookdeck Event Gateway includes a built-in transformation engine with both a code editor and a visual editor. You can modify payloads, restructure data, and normalize events from different providers into a consistent format before delivery.
Svix Ingest offers JavaScript functions for payload transforms, available on Professional plans and above.
Both products let you transform payloads. Event Gateway's visual editor provides a lower barrier to entry for teams that prefer not to write code for every transformation, while you can use JavaScript in both Hookdeck and Svix, offering full programmatic flexibility.
Observability and debugging
Observability is where the gap between the two products is widest.
Hookdeck Event Gateway provides real-time event tracing with visual traces that show an event's full lifecycle from ingestion through transformation, filtering, and delivery. You get detailed logs with full-text search across your entire event history, the ability to filter by headers, query parameters, paths, errors, or JSON syntax, and bulk operations to pause, replay, or cancel events. Advanced monitoring covers delivery, transformation, and backpressure, with metrics export to Datadog, Prometheus, and New Relic on Growth plans and above.
Beyond raw event data, Event Gateway also has a structured Issues system. Rather than presenting a flat list of failed deliveries, Event Gateway can automatically create and track issues based on configurable issue triggers — for example, when a destination has consecutive failures, when a transformation errors, or when backpressure thresholds are exceeded. Each issue captures the root cause context, and your team can inspect it, take resolution steps, and update the issue status to keep everyone aligned. This turns webhook failures from a wall of error logs into a manageable operational workflow.
Svix Ingest offers a basic dashboard showing successes and failures over a rolling 6-hour window. Monitoring covers delivery failures only. Logging supports filtering by tag, date, message ID, or event ID, but there's no full-text search. OpenTelemetry metrics export (for sending HTTP and message attempts) is available on Professional plans and above. There is no equivalent to Event Gateway's issue tracking or custom issue triggers.
When something goes wrong with a webhook delivery, Event Gateway lets you trace the event visually, search across your full event history, inspect headers and payloads, bulk-replay failed events, and track the resolution through its Issues system. With Svix Ingest, you're working with a 6-hour window and basic filters, with no structured way to track and communicate resolution across your team.
Alerting
When webhook deliveries fail, you need to know about it quickly.
Hookdeck Event Gateway can send alerts via Email, Webhooks, Slack, Microsoft Teams, PagerDuty, and OpsGenie. This means alerts can go directly to the on-call channel your team already uses.
Svix Ingest supports alerting via Email and Webhooks.
If your incident response workflow relies on Slack, PagerDuty, or OpsGenie, Event Gateway integrates natively. With Svix, you'd need to build a webhook-to-Slack (or similar) integration yourself.
Content type support
Hookdeck Event Gateway handles JSON, XML, form-encoded, JWT, and other content types. This is particularly important for providers that don't send JSON — some legacy systems use XML and JWT-based payloads are common, too.
Svix Ingest supports JSON and form-encoded content only.
If every webhook provider you work with sends JSON, this won't matter. But if you're integrating with legacy providers with XML callbacks, or any system that doesn't use JSON, Svix Ingest will require you to normalize payloads before they reach Svix, or handle the conversion downstream.
Retry logic and recovery
Hookdeck Event Gateway supports both linear and exponential backoff retry policies with customizable parameters, plus manual bulk retry for recovering from outages. You can replay individual events or bulk-replay entire time ranges of failed deliveries.
Svix Ingest provides automatic retries with exponential backoff.
The key difference is recovery flexibility. Event Gateway's bulk retry and manual replay capabilities make it straightforward to recover from extended outages — you can select a time range of failed events and replay them all at once. With Svix, recovery is limited to the automatic retry policy.
Signature verification
Both products verify the authenticity of incoming webhooks, but Event Gateway supports a broader range of authentication methods.
Hookdeck Event Gateway supports HMAC, Basic Auth, Bearer Token, and API key verification.
Svix Ingest supports HMAC, Basic Auth, and Bearer Token verification.
The difference is API key support in Event Gateway. If any of your webhook providers authenticate using API keys, Event Gateway handles that natively while Svix would require a workaround.
Developer tools
Hookdeck Event Gateway includes the Hookdeck Console with built-in sample webhooks from 60+ real providers for instant testing, and the Hookdeck CLI — a full-featured local development tool (often used as an ngrok alternative) with a terminal UI (TUI), event replay, and local forwarding.
Svix Ingest offers Svix Play (a free webhook URL with inspection) and the Svix CLI with local relay capability.
The Console's sample webhooks from real providers save meaningful development time — you can test your handler against realistic payloads from Stripe, GitHub, Shopify, and dozens of other providers without setting up accounts or triggering real events. The CLI's TUI provides a richer local development experience than a basic relay.
Logging and search
Hookdeck Event Gateway provides advanced logging with full-text search and the ability to filter based on headers, query parameters, paths, errors, or JSON syntax. This means you can search for example, on a specific customer email address across months of events, find all events with a particular error, or filter by any header value.
Svix Ingest supports basic logging with filtering by tag, date (before/after), message ID, or event ID. There is no full-text search capability.
The practical impact is most obvious during incident investigation. With Event Gateway, you can search across your entire event history using any field. With Svix Ingest, you need to know the specific message ID or event ID you're looking for, or browse by date and tag.
Infrastructure-as-code
Hookdeck Event Gateway provides a Terraform provider and a full API and CLI for managing configuration programmatically.
Svix Ingest also provides a Terraform provider, API, and CLI.
Both products are on equal footing here.
Compliance and data residency
Svix holds SOC 2 Type II, HIPAA, PCI-DSS, GDPR, CCPA, and PIPEDA certifications, and offers hosting in US, EU, and custom regions. This is a genuine advantage for teams operating in regulated industries or with strict data residency requirements.
Hookdeck holds SOC 2 Type II, GDPR, CCPA, and PIPEDA certifications. Event Gateway is currently hosted in the US only. Hookdeck's SOC 2 Type II covers approximately 75% of HIPAA control requirements, and Hookdeck signs Business Associate Agreements (BAAs) for customers who need them.
If your organization has a hard compliance requirement for HIPAA, PCI-DSS, or EU data residency, Svix meets those out of the box today. For many teams, Hookdeck's SOC 2 Type II combined with a BAA provides sufficient coverage, but it's worth validating against your compliance requirements.
Uptime SLAs
Hookdeck Event Gateway offers a 99.999% uptime SLA across all paid plans.
Svix Ingest offers tiered SLAs: 99.9% on Free, 99.99% on Professional, and 99.999% on Enterprise.
Event Gateway's 99.999% SLA is available starting from the Team plan at $39/mo. To get the same SLA from Svix, you need to be on their Enterprise tier.
Pricing
Hookdeck Event Gateway pricing starts with a free tier (10K events, 3-day retention, 1 user), a Team plan at $39/mo with pay-as-you-go pricing ($0.33/100K events and unlimited users), and a Growth plan at $499/mo with SLAs and SSO.
Svix Ingest starts with a free tier (50K messages, 30-day retention, 3 users), a Professional plan at $490/mo, and a custom-priced Enterprise tier.
You can get more events, longer retention, and more users on Svix's free tier. However, the jump from free to paid is steep: $490/mo for Professional. Event Gateway's Team plan at $39/mo provides a far more accessible entry point for production workloads, with unlimited users included.
At scale, Event Gateway's pay-as-you-go pricing ($3.30/million events) is significantly cheaper than Svix's overage rate ($100/million messages on Professional).
When to choose Hookdeck Event Gateway
Event Gateway is the stronger choice when you need deep observability and debugging across your webhook traffic, when you're integrating with many different providers (120+ pre-configured sources), when you need filtering and deduplication at the infrastructure level, when you deal with non-JSON payloads, or when you want production-grade features at an accessible price point starting at $39/mo.
When to choose Svix Ingest
Svix Ingest may be the right choice if you're already using Svix Dispatch for outbound webhooks and want to consolidate on a single platform, if your webhook receiving needs are straightforward (low volume, JSON-only, minimal routing), if you have hard compliance requirements for HIPAA, PCI-DSS, or CCPA certification, if you need EU or custom-region data residency, or if the bundled pricing of Dispatch + Ingest on a single Svix plan makes sense for your use case.
Conclusion
Both Hookdeck Event Gateway and Svix Ingest can receive webhooks and forward them to your services. The difference is in the depth of what happens in between. Event Gateway provides a purpose-built inbound webhook platform with durable queueing, advanced filtering, deduplication, visual tracing, full-text search, and broad content type support. Svix Ingest provides basic ingest with JavaScript-based routing and transforms on paid plans.
For teams that treat inbound webhooks as critical infrastructure (where missed events, duplicate processing, and limited visibility are real operational risks) Event Gateway offers significantly more depth. For teams with simpler inbound needs already invested in the Svix ecosystem, Ingest provides a convenient add-on to their existing platform.
