How we cut build times by two-thirds by deleting our CMS
Sentry replaced its legacy headless CMS with Astro, Markdown, and AI-driven automation — cutting build times from 14 minutes to under 4 and eliminating broken builds.

You don’t need to pick one: how Sentry and OpenTelemetry work together
Teams with existing OpenTelemetry instrumentation do not need to choose between OTel and Sentry. Keep OTel on the backend, use the Sentry SDK on the frontend, and export OTLP events to Sentry.

Your agent can't fix what it can't see
The bottleneck for self-healing software isn't agent intelligence. It's that agents have no idea what actually broke in production. Sentry MCP and the CLI bridge that gap.

From vibe code to production-ready: observability for Next.js and Supabase apps
Supabase gives you query insights and logs, but it can't trace across your full stack. Here's how to connect Next.js, Supabase Edge Functions, and Postgres with distributed tracing, log drains, and AI-assisted debugging in Sentry.

Fixing JavaScript observability, one library at a time
Sentry is adding TracingChannel support to 44 JavaScript libraries upstream, replacing fragile monkey-patching with native observability that works across all runtimes.

When agents orchestrate agents, who's watching?
Multi-agent AI systems fail silently. Learn what proper observability looks like when agents orchestrate agents, and how Sentry keeps you in control.

No more monkey-patching: Better observability with tracing channels
Monkey-patching in CJS and module hooks in ESM both instrument libraries from the outside. Tracing Channels let libraries emit their own telemetry — and the ecosystem is already moving.

Debugging multi-agent AI: When the failure is in the space between agents
When an agent's tool call silently degrades the input to a completely different agent two steps later, standard monitoring won't catch it. Here's how to find bugs that live between agents.

AI agent observability: The developer's guide to agent monitoring
Most discussions about agent observability read like outdated compliance checklists with "AI" substituted for older technologies. They emphasize comprehensive…

Seer fixes Seer: How Seer pointed us toward a bug and helped fix an outage
How Sentry's AI debugging tool Seer helped identify and fix a cascading region blocklist bug that caused an outage in Seer's own EU deployment.

Do you need an MCP to build your native app?
Do you need an MCP to build your native app? Surprisingly, modern agents succeed either way. The real difference is how much time, cost, and context you waste along the way.
