Svix vs Convoy vs Hook0: Best Self-Hosted Webhook Management 2026

When your application sends webhooks to third-party services, things break. Endpoints go offline, payloads get rejected, rate limits kick in, and your users never hear about important events. Building reliable webhook delivery infrastructure from scratch means implementing retry logic, signature verification, event versioning, delivery status tracking, and a dashboard for debugging — weeks of work that distracts from your core product.

Open-source webhook management platforms solve this problem by providing a dedicated service that handles outbound webhook delivery with enterprise-grade reliability. In this guide, we compare the three leading self-hosted options: Svix, Convoy, and Hook0.

Why Self-Host Your Webhook Infrastructure

SaaS webhook services like Hookdeck, webhook.site, and various managed platforms handle the heavy lifting, but they come with trade-offs:

• Data residency: Webhook payloads often contain sensitive user data. Self-hosting keeps everything in your infrastructure, avoiding third-party data processing.
• Cost at scale: Per-event pricing models get expensive quickly when you’re dispatching hundreds of thousands of webhooks per day.
• Custom integrations: Self-hosted solutions let you modify delivery behavior, add custom middleware, or integrate with internal systems.
• No vendor lock-in: Your webhook event schema and delivery infrastructure belong to you. Migrating between SaaS providers is painful.
• Latency control: Running the webhook dispatcher in the same data center as your application reduces round-trip latency for event ingestion.

For teams that treat webhooks as a core part of their product — SaaS platforms with developer ecosystems, marketplace applications, or any service offering integrations — self-hosting webhook infrastructure is the logical choice.

For related reading, see our guide on self-hosted webhook relay and tunneling options for forwarding webhooks to localhost during development, and our comparison of self-hosted message queue solutions since both Svix and Convoy rely on Redis-backed queues for event scheduling.

Svix: Enterprise-Ready Webhook Service

Svix is the most popular open-source webhook delivery platform with over 3,100 GitHub stars. Written in Rust, it prioritizes developer experience, security, and reliability. Svix is backed by a commercial company offering a managed cloud service alongside the open-source server.

Key Features

• Cryptographic signature verification: Every webhook delivery is signed using HMAC-SHA256, ensuring recipients can verify authenticity
• Idempotency and replay protection: Built-in deduplication prevents duplicate deliveries
• Endpoint management per application: Organize webhooks by application/tenant with separate endpoint configurations
• Automatic retries with exponential backoff: Failed deliveries are retried on a configurable schedule
• Message transformation: Transform event payloads before delivery using templates
• Multi-tenant architecture: Designed for SaaS products that need to manage webhooks for many customers
• SDK support: Official SDKs for Python, Go, JavaScript/TypeScript, Java, C#, Ruby, PHP, and Rust

Architecture

Svix uses a Redis-backed queue for event scheduling, PostgreSQL for persistent storage, and PgBouncer for connection pooling. The worker service pulls events from the queue and delivers them to configured endpoints. This architecture handles high-throughput scenarios with thousands of endpoints per application.

When to Choose Svix

Svix is the best fit if you run a multi-tenant SaaS product, need mature SDK coverage across many languages, or want the most battle-tested option with the largest community. Its MIT license means zero restrictions on commercial use.

Convoy: Cloud-Native Webhook Gateway

Convoy positions itself as “The Cloud Native Webhooks Gateway.” Written in Go, it focuses on event-driven architecture with advanced delivery features. Convoy is developed by Frain and has nearly 2,800 GitHub stars.

Key Features

• Dynamic event routing: Route events to different endpoints based on payload content, event type, or custom rules
• Rate limiting per endpoint: Protect downstream services from being overwhelmed by high event volumes
• Signature verification with multiple algorithms: Supports HMAC-SHA256 and custom signing schemes
• Event replay: Replay any historical event to any endpoint for debugging or migration
• Project-based isolation: Organize webhooks into projects with separate configurations, ideal for multi-team environments
• Built-in observability: Native Jaeger integration for distributed tracing of webhook delivery pipelines
• API-first design: Comprehensive REST API for programmatic management of endpoints, events, and deliveries

Architecture

Convoy runs as a single Go binary with PostgreSQL for persistence and Redis for caching/queuing. Its architecture includes a gateway component for receiving events, a worker for processing deliveries, and a UI dashboard. The optional Jaeger integration provides deep visibility into delivery latency and failures.

When to Choose Convoy

Convoy excels when you need advanced event routing logic, built-in observability with distributed tracing, or a Go-native stack that aligns with your existing infrastructure. Its dynamic routing capabilities make it ideal for complex event-driven architectures.

Hook0: Lightweight Open-Source Webhook Server

Hook0 is a newer entrant focused on simplicity and ease of deployment. Written in Rust like Svix, it aims to provide core webhook delivery features without enterprise complexity. With 1,400 GitHub stars, it’s the smallest of the three but actively maintained.

GitHub: hook0/hook0 | Stars: 1,400 | Language: Rust | License: NOASSERTION

Key Features

• Simple API for webhook management: Clean REST API with Swagger/OpenAPI documentation
• Built-in email notifications: Ships with Mailpit integration for email-based delivery notifications
• Frontend dashboard: Includes a pre-built web UI for monitoring deliveries and managing endpoints
• Worker-based delivery: Separate output worker process handles asynchronous delivery with configurable worker names
• Target IP validation: Optional security feature to prevent webhook delivery to internal/private IPs (disabled by default in compose)
• Swagger API documentation: Auto-generated API docs available at runtime for easy integration
• Minimal dependency footprint: Requires only PostgreSQL — no Redis or additional services

Architecture

Hook0’s architecture is deliberately simpler than Svix and Convoy. It uses PostgreSQL as its sole data store, with separate services for the API, frontend, and output worker. The mail service (Mailpit) is bundled for email notifications. This simpler stack makes it faster to deploy and easier to operate.

When to Choose Hook0

Hook0 is ideal for small teams or individual developers who want webhook management without the operational overhead of Redis, PgBouncer, or tracing infrastructure. Its bundled UI and email notifications provide a complete out-of-the-box experience.

For most teams starting out, Svix offers the best balance of features, reliability, and community support. If your requirements include advanced routing or observability, Convoy is worth the additional infrastructure. If simplicity is your primary concern, Hook0 delivers a complete experience with minimal moving parts.

If you’re also evaluating self-hosted API gateways for inbound traffic management, pairing one with an outbound webhook platform gives you complete control over your API event lifecycle.

FAQ

What is a webhook management platform?

A webhook management platform is a dedicated service that handles the sending, delivery tracking, retry logic, and signature verification of outbound webhooks. Instead of building this infrastructure into your application, you offload it to a specialized service that guarantees delivery, provides dashboards for monitoring, and handles edge cases like endpoint downtime and rate limiting.

Can I self-host webhook platforms for free?

Yes. Svix, Convoy, and Hook0 are all open-source and free to self-host. You only need to pay for the infrastructure (servers, databases) to run them. Svix is MIT-licensed with no commercial restrictions. Convoy and Hook0 also allow self-hosting, though their exact license terms should be reviewed for production use.

How do these platforms handle failed webhook deliveries?

All three platforms implement automatic retry mechanisms with exponential backoff. When an endpoint returns an error or times out, the platform schedules a retry after an increasing delay (e.g., 1 minute, 5 minutes, 30 minutes, 1 hour). After a configurable number of retries, the delivery is marked as failed and can be replayed manually. Svix and Convoy provide detailed delivery logs showing each attempt’s status code and response body.

Do I need Redis to run these platforms?

Svix and Convoy both require Redis for event queuing and caching. Hook0 is the only platform that runs with PostgreSQL alone, making it the simplest to deploy. If you want to minimize infrastructure dependencies, Hook0 is the best choice. If you already run Redis in your stack, Svix and Convoy add minimal overhead.

How do webhook signatures work?

Webhook signatures use HMAC-SHA256 to create a cryptographic hash of the webhook payload combined with a secret key. The signature is sent in the HTTP header of each webhook delivery. The receiving service recalculates the hash using the same secret key and compares it to the received signature. If they match, the payload is authentic and hasn’t been tampered with in transit. All three platforms support this mechanism.

Can these platforms handle high webhook volumes?

Yes, but with different capacities. Svix is designed for enterprise-scale with PgBouncer connection pooling and Redis-backed queues capable of handling millions of events per day. Convoy’s Go-based architecture is optimized for cloud-native deployments with horizontal scaling. Hook0’s simpler architecture is suitable for moderate volumes — sufficient for most small to medium applications but not designed for the same scale as Svix.
