Datadog is a full-stack APM platform that monitors your infrastructure, traces, and logs — it can alert on webhook failures only if you write custom instrumentation in your handler. Webhook Guardian is purpose-built for webhook delivery monitoring: it reads the delivery logs that Stripe, Shopify, and GitHub maintain via read-only OAuth, requires zero code changes, and costs $29/month. The critical difference is the data source — Datadog monitors your handler, while Webhook Guardian reads the platform's delivery log directly, catching failures that never reach your handler.
Datadog vs Webhook Guardian: Full APM vs Purpose-Built Webhook Monitoring
Teams that already use Datadog often assume it handles webhook monitoring. It can — but the path to getting there is longer than most expect, and the coverage has a blind spot that matters.
Here is exactly what Datadog can and cannot do for webhook failure detection, and where Webhook Guardian fills the gap.
What Is Datadog?
Datadog is a full-stack APM and observability platform. It collects infrastructure metrics, distributed traces, logs, and custom metrics from across your entire stack — servers, containers, databases, third-party services, and application code. Teams use it for uptime monitoring, performance profiling, log analysis, and alerting on anomalies across complex distributed systems.
Datadog is generalist by design. It can monitor almost anything, but it does so through agents installed on your infrastructure and instrumentation embedded in your application code. At $15 or more per host per month, it is priced for teams running substantial infrastructure across multiple services.
What Is Webhook Guardian?
Webhook Guardian is a purpose-built webhook delivery monitor. It connects to Stripe, Shopify, and GitHub via read-only OAuth and polls the delivery logs those platforms maintain for every webhook attempt — recording HTTP response codes, timestamps, retry counts, and outcomes.
When Webhook Guardian detects a failed delivery, it sends a Slack or email alert with the event type, error code, retry count, and a one-click replay link. There are no agents to install, no instrumentation to write, and no infrastructure to change. Setup takes approximately 2 minutes and costs $29/month.
Can Datadog Alert on Webhook Failures?
Yes — but with significant caveats. Datadog does not natively know about your Stripe, Shopify, or GitHub webhook deliveries. To surface webhook failures in Datadog, your team would need to:
- Instrument your webhook handler to emit a custom metric (e.g.,
webhook.delivery.failed) whenever it detects a failure - Create a Datadog dashboard to visualize that metric
- Write a Datadog monitor with alert conditions and notification routing
This is achievable for teams with Datadog expertise. But it requires engineering time upfront, and it has a critical blind spot.
What Is the Blind Spot When Using Datadog for Webhook Monitoring?
Datadog monitors your handler. Webhook Guardian monitors the platform's delivery log. These are different data sources, and the difference matters.
When Stripe attempts to deliver a webhook, it records the outcome in its own delivery log — including cases where your endpoint returned a non-2xx, cases where it timed out, and cases where Stripe itself marked the delivery as failed before your handler processed it. Datadog has no access to that log. It only sees what your instrumented handler emits.
If Stripe attempts delivery and your endpoint returns a 500 before your instrumentation code runs, Datadog may not capture the failure. If Stripe marks a delivery failed due to a timeout and schedules a retry, Datadog knows nothing about it. Webhook Guardian reads Stripe's log directly — it sees exactly what Stripe recorded, not what your handler reported.
How Do Datadog and Webhook Guardian Compare Feature by Feature?
| Feature | Webhook Guardian | Datadog |
|---|---|---|
| Setup time | ~2 minutes | Hours to days (instrumentation + dashboards + monitors) |
| What it monitors | Stripe/Shopify/GitHub delivery logs | Your handler and infrastructure |
| Data source | Platform's own delivery log (read-only OAuth) | Custom metrics from your instrumentation |
| Alert on first failure | ✓ Yes — detects platform-side failures | ✓ Only if your handler emits the metric |
| Replay failed events | ✓ One-click replay link in alert | ✗ Not applicable |
| Cost | From $29/month | $15+/host/month (plus custom metrics pricing) |
| Reads Stripe delivery logs | ✓ Yes — directly via OAuth | ✗ No — only what your code emits |
| Infrastructure agents required | ✗ None | ✓ Agent on every monitored host |
When Should You Use Datadog for Webhook Monitoring?
Datadog makes sense for webhook visibility when:
- Your team already has Datadog deployed and the instrumentation cost is acceptable
- You want webhook failure metrics alongside the rest of your application observability in a single pane
- Your team has the bandwidth to write, maintain, and iterate on custom metrics, dashboards, and monitors
- You are monitoring a custom webhook system you built yourself, not a third-party platform's delivery log
When Should You Use Webhook Guardian?
Webhook Guardian makes sense when:
- You want to know when Stripe, Shopify, or GitHub webhook deliveries fail — without writing any instrumentation code
- You need to catch failures that occur on the platform side, before your handler processes the event
- Your team does not have Datadog, or does not want to add webhook monitoring complexity to an existing Datadog setup
- You want failure alerts with payload context and a one-click replay link, not just a metric threshold breach
- You want monitoring in place in 2 minutes, not after an engineering sprint
What Is the Core Difference Between Datadog and Webhook Guardian for Webhooks?
Datadog monitors what your infrastructure emits. Webhook Guardian reads what the platform recorded. For webhook delivery failures specifically, the platform's record is the authoritative source — and only Webhook Guardian reads it directly.
