Why Grumpy?

Because your code deserves honest feedback — and you deserve tools that actually help you ship better software.

Error tracking shouldn't be boring.

Most error tracking tools give you a line number, a stack trace, and a dashboard you check once a week. They're polite, they're clinical, and they're easy to ignore.

Grumpy is different. We use AI to analyze your crashes in real-time, deliver human-readable explanations with suggested fixes, and send them directly to your Slack or Discord — where your team actually lives. No more silent failures. No more "we'll look at it Monday."

Three voices. One mission: fix your code.

Every team has its own culture. That's why Grumpy speaks in three distinct AI personas, configurable at the organization level:

Grumpy

Sarcastic, direct, and brutally honest. For teams with thick skin who want their bugs called out — loudly.

Friendly

Supportive, encouraging, and positive. Perfect for junior-heavy teams or when HR asks you to "tone it down."

Professional

Strategic, objective, enterprise-grade. Strictly factual root-cause analysis for regulated industries and audit trails.

Grumpy Rescue Engine: AI patches while you sleep.

When your app crashes in production — whether it's your code or a third-party dependency — you shouldn't have to scramble to deploy a hotfix at 2 AM. The Rescue Engine uses AI to automatically generate and deploy targeted fixes that neutralize known crashes in real-time.

Think of it as an immune system for your application. Grumpy detects the crash, generates a fix, and applies it instantly. You wake up to a resolution, not a fire.

"Not My Fault" Engine: Blame the right package.

Grumpy automatically detects when a crash originates from a third-party dependency — not your code. It identifies the responsible package, files an automated notification to the maintainer, and clearly separates "app bugs" from "dependency bugs" in your dashboard.

Keep your dependencies up to date, let Grumpy handle the accountability, and focus on what matters: shipping features.

Bring Your Own AI. Zero token costs from us.

Grumpy works out of the box with hand-crafted analysis. But when you plug in your own AI key — OpenAI, Anthropic, Groq, or even local models via Ollama — you unlock deep, contextual code analysis powered by the model you choose.

We never charge you for AI tokens. Your key, your provider, your scale. If your API goes down, Grumpy seamlessly falls back to standard mode. No lock-in, no surprises.

Built to make your team better.

At its core, Grumpy is about culture. We gamify code stability with streak challenges, make error resolution visible to the whole team, and turn debugging from a chore into a shared win.

Write solid code, and Grumpy stays quiet. Ship something questionable, and we'll see you in #alerts-production — with a fix suggestion already attached.
