Record Everything Your AI Agent Does. Share It On Your Terms.

Record Everything Your AI Agent Does. Share It On Your Terms.

A coding agent running on your laptop is the most revealing process you own. Every prompt you typed, every file it read, every shell command it ran, every secret that scrolled past in a tool result. That is exactly the telemetry you want when the agent goes sideways — and exactly the telemetry nobody dares to ship to a shared observability backend.

Micromegas now lets you record the whole thing and decide, per person and per team, who gets to read it. The data never moves when you change your mind.

Stop Guessing Why Blender Crashed

Stop Guessing Why Blender Crashed

An artist files a ticket: "Blender crashed while I was sculpting." No .blend, no repro steps, no idea which add-ons were running. You try to reproduce it, fail, and close it cannot reproduce. Every team that supports a DCC tool knows this loop.

One Binary, Whole Stack

One Binary, Whole Stack

The full Micromegas stack — ingestion, analytics, maintenance, web UI — now fits in a free-tier VM. One binary, one Postgres, one object store. That's it.

This is the micromegas-monolith: a single process that runs all four roles on one tokio runtime, sharing a data-lake connection, a cache, and a SIGTERM fanout. Spin it up on a free-tier VM, your laptop, or whatever throwaway instance your cloud provider gives away. Point your instrumented app at it. Get logs, metrics, and traces with a full SQL query interface and a web UI, for essentially zero running cost.

That's the pitch for personal telemetry. For teams it's also the fastest demo path: one compose file, no orchestration.

Micromegas Speaks Open Telemetry Now

Micromegas Speaks Open Telemetry Now

Micromegas's native instrumentation — a Rust crate and an Unreal Engine plugin — gives you about 20ns per event and 100k events per second per process. It's the cheapest way to get telemetry out of code you control. The hard part is "code you control" — production systems are full of code you can't recompile.

We Put a Data Warehouse in Your Browser

Apache DataFusion already supports compiling to WebAssembly — so we took advantage of it. Full SQL running client-side, the same query engine that powers the Micromegas backend, now running in a browser tab. And it scales your analytics compute for free.

Your Crash Database Can't Calculate MTBF

Your Crash Database Can't Calculate MTBF

The most basic stability statistic is Mean Time Between Failures, and your crash reporting service can't tell you what it is. Here's why, and how unified telemetry fixes it with a single SQL query.

How Costly Really Is Splunk?

I asked Gemini to estimate how much it would cost to run my $1k workload on Splunk and it's telling me $24k — including only logs & metrics, excluding tracing.
