The merge gate for embedded firmware

Don't let broken firmware
reach the board.

EmbedCI gives every pull request a single pass/fail verdict — build, boot, behavior, flash/RAM, stack, and MISRA. Free tells you whether it's safe to merge; Team makes it a required check that blocks the merge when it isn't. It runs in emulation, so there's no hardware lab to maintain.

Product

What it does

One pass/fail merge gate on every PR — and the footprint, stack, MISRA, and behavioral signal behind the verdict.

Vision

Where we're going

Firmware testing is a decade behind software. We're building toward deep, signal-aware verification that runs without a hardware lab.

On every pull request

The numbers engineers actually track

✓ Boot + behavioral tests

Runs your firmware in Renode and asserts UART, GPIO, and register behavior.

✓ Footprint tracking

Flash & RAM with per-section breakdown and deltas vs the last build.

✓ Stack high-water

Worst-case stack frame, so overflow shows up before hardware does.

✓ Static analysis

cppcheck + MISRA C, reported per finding (rule + file:line).

✓ Budget gates

Set flash / RAM / stack / MISRA limits — a violation fails the PR.

Demo

This is what EmbedCI posts on your PR.

A real check on a real pull request: firmware footprint, stack usage, MISRA findings, and pass/fail budget gates — with each gate showing its limit and actual value, so a developer knows exactly what to fix.
