Should I build webhooks myself or use a tool like Svix?

Usually: build webhooks yourself only if you have very simple needs. If webhooks are part of your product’s core integration story, using a tool like Svix is often the better choice.

Build it yourself if:

• You only need to send a small number of webhooks
• Delivery reliability isn’t mission-critical
• You don’t need retries, signing, monitoring, or replay
• You’re okay owning edge cases like:
  • endpoint failures
  • retry logic
  • deduplication
  • event ordering
  • secret rotation
  • observability

Use Svix or a similar tool if:

• Webhooks are important to your customers
• You need reliable delivery with retries and backoff
• You want security features like signing and verification
• You need logs, replay, and debugging
• You expect customers to manage many endpoints
• You want to avoid building and maintaining infrastructure that seems simple at first but grows tricky fast

The hidden cost of building it yourself

Webhooks look straightforward:

1. send HTTP request
2. get 200 OK
3. done

But in practice you need to handle:

• transient network failures
• timeouts
• duplicate deliveries
• idempotency
• poison endpoints
• dead-letter handling
• payload versioning
• per-customer retries
• visibility for support/debugging

That can become a lot of engineering time.

Rule of thumb

• Internal app or low-stakes notifications: build it yourself
• Customer-facing integrations: strongly consider Svix
• If integrations are strategic: use a dedicated webhook platform unless you have a clear reason not to

Practical recommendation

If you’re unsure, start with:

• a simple webhook prototype
• then ask whether you’ll need retries, logs, replay, signing, and scaling within the next 6–12 months

If the answer is yes to several of those, buying is likely cheaper than building.
