One breaking change,
start to finish.
A provider ships a breaking change upstream overnight. By morning there is a pull request on your branch that fixes it, with your tests passing in an isolated container.
Autonomous API
maintenance.
Browniie watches hundreds of the most popular APIs, and when a provider ships an upstream breaking change, it detects the exact changes that break your code and opens a pull request with a fix in minutes.
From their change
to your branch.
We call it SWARM: five steps that run around the clock, so nobody on your team has to.
Scan your codebase
Browniie reads your codebase and maps every external API call down to the file and line, across Python, TypeScript, JavaScript, Ruby, Go, and Java.
Watch the vendors
Every day Browniie captures the specifications and SDKs of hundreds of the most popular API providers and stores them permanently: a record of exactly what each one looked like on each day.
Analyze the impact
When a provider ships a change, Browniie works out whether it touches your code, and where. If it doesn't, you hear nothing.
Report it to you
What changed, which lines it hits, and how it will be fixed, delivered where your team already works: a GitHub issue, a pull request comment, Slack, or email.
Mend it, open a PR
Most fixes are deterministic rules built from the provider's own migration guide. When no rule fits, an AI drafts one that has to pass your test suite in an isolated container first. Either way, a pull request lands in minutes.
Nobody reads the changelog.
And nothing you run tells you which lines it just broke.
A typical company calls a dozen or more external services. Those providers change constantly, and the code calling them breaks quietly. Every break is engineering time spent keeping old code alive instead of building what's next.
Dependency bots watch packages.
Not the web APIs you call. A provider can remove a field without shipping a new SDK version, and nothing in your lockfile moves.
Status monitors watch uptime.
They tell you something changed. They have never read your code, so they cannot tell you whether it matters.

Illustrative.
Deprecation emails get archived.
A ninety-day notice about a field you might not use loses to whatever is due on Friday. Every time.
You choose how much authority it gets.
Per repository, and reversible.
Start at Report. Move down when the drafts have earned it. No mode merges anything, and no mode writes to your default branch.
Tell me.
A GitHub issue, a pull request comment, Slack, or email. Stays quiet when nothing has happened, which is most days.
No write accessDraft it for me.
Opens a draft pull request you review and merge. Every draft is labeled by what produced it and how it was verified.
Pull requestsJust fix it.
Applies verified fixes straight to a branch. Rule-based changes and test-passing drafts, no waiting on a reviewer.
BranchesIt fixes your code without breaking it.
We will never ship you a break.
Deterministic first, tested always. If a change can't pass your own test suite, it never becomes a pull request.
Read the security modelDeterministic by default.
Most fixes are rules, not guesses. Each one is built from the provider's migration guide, every step cites their docs, and the same change produces the same diff every time.
Tested before you see it.
Fixes are verified against your own suite with no network interface, no inherited environment, and no mounted credentials. A draft that fails is discarded.
Reports carry paths, not code.
What leaves is file paths, line numbers and symbol names, built from an allowlist of fields. Source is not something the payload has a place for.
Your dependencies are watched. The APIs behind them aren't.
APIs change.
Your code should keep up.
Try Browniie on your next upstream break. We're onboarding a first group of teams before opening it up. If your codebase calls more than a handful of external APIs, leave your email.
