Your AI writes code.
We make sure it works.

AI coding tools move fast and sound confident — but they make mistakes your team might not catch. StableStack spots those problems before they become expensive ones.

Zero setup required

Works on Python, JavaScript, TypeScript, and C#/Unity. Free, no signup.

$ pip install stablestack

Trusted by teams shipping faster with AI — without the hidden risks

The hidden risk

AI moves fast. Mistakes move faster.

AI sounds confident, even when it's wrong

AI coding assistants can introduce subtle bugs and security gaps that look perfectly fine at first glance. They don't flag their own uncertainty — they just keep going.

Your team can't review everything

When AI generates code at scale, manual review becomes a bottleneck. Important details slip through — and problems often don't surface until something breaks in production.

The result?

Teams ship faster than ever, but with less visibility into what's actually going out the door. Small issues compound into costly fixes, security reviews, and late-night firefighting.

The solution

Automatic quality checks for AI-generated code

StableStack runs in the background, automatically scanning code as it's written. It catches the mistakes that AI tools confidently introduce — so your team can ship with confidence.

Connect your codebase

Takes a few minutes. Works with any setup.

We scan automatically

Every change gets checked. No extra work for your team.

Issues surface early

Problems get flagged before they reach customers.

AI-native workflow

Slash commands for Claude Code. Auto-installed.

Run stablestack once and get powerful slash commands injected directly into Claude Code. Zero config. No plugins. No extensions.

/check

Runs all StableStack quality checks on your codebase and fixes issues inline -- right inside your Claude Code session. No context switching, no copy-pasting error output.

> claude

/check

Found 3 issues. Fixing inline...

SESS002 thread-session-safety -- fixed

ENV001 missing-env-validation -- fixed

AUTH003 jwt-expiry-missing -- fixed

/fix-production

Auto-detects your CI/CD pipeline -- GitHub Actions, Vercel, Amplify, Netlify, and more. Monitors your build, diagnoses failures, and applies fixes until production is green.

> claude

/fix-production

Detected: GitHub Actions + Vercel

Build failed: type error in api/route.ts

Applying fix...

Build passing. Production is green.

Zero setup required

Install StableStack and the slash commands are automatically added to Claude Code. No other tool gives you AI-native commands that work inside your coding agent.

Cost optimization

Same prompt, same result. Stop paying twice.

LLM API calls are expensive and non-deterministic. StableStack's disk cache eliminates redundant calls — same arguments return the same result from local storage, not the API.

Before

# Every call hits the API

summarize("quarterly report")

-> $0.03, 1.2s

summarize("quarterly report")

-> $0.03, 1.1s (same prompt!)

summarize("quarterly report")

-> $0.03, 1.3s (paying again)

After

@cache

def summarize(text): ...

summarize("quarterly report")

-> $0.03, 1.2s (API call)

summarize("quarterly report")

-> $0.00, 0.001s (from cache)

summarize("quarterly report")

-> $0.00, 0.001s (from cache)

One command to install

$ stablestack deterministic-ai

Created stablestack_cache.py

Added .cache/ to .gitignore

Created .claude/commands/deterministic-ai.md

Drops a self-contained stablestack_cache.py into your project. Zero dependencies. Works with OpenAI, Anthropic, or any function you want to cache.

Performance visibility

See where every millisecond goes.

LLM calls are the slowest part of AI applications. StableStack's ChatTimer shows exactly how time splits across prompt building, API calls, and response parsing — in the terminal and in the browser.

One command to install

$ stablestack add-llm-timing

Created stablestack_timer.py

Added .stablestack/timing/ to .gitignore

Drops a self-contained stablestack_timer.py into your project. Zero dependencies. Console waterfall + HTML visualization. Works with OpenAI, Anthropic, and LangChain.

Security infrastructure

OAuth tokens expire. Your app shouldn't break.

Encrypted token storage, automatic rotation before expiry, a React dashboard to see every credential's status, and a cron job that keeps everything alive. Python and TypeScript.

Encrypted storage

AES-256-GCM encryption for all tokens at rest. Fernet and raw AES-GCM implementations included. Transparent encrypt/decrypt via model properties.

Auto-rotation

Generic OAuth provider interface with configurable thresholds. Cron job refreshes tokens before they expire. Supports any OAuth2 provider out of the box.

React dashboard

See every credential's expiry status at a glance. Test tokens, force refresh, rotate all expiring tokens, or run a dry run. Drop-in React component.

One command to install

$ stablestack add-token-manager

Created stablestack_token_manager/encryption.py

Created stablestack_token_manager/api.py

Created scripts/rotate_tokens.py

Created stablestack_token_manager/ui/TokenDashboard.tsx

Created .claude/commands/token-manager.md

Generates a complete token management system — encryption, CRUD API, automatic rotation cron job, and React dashboard. Auto-detects Python or TypeScript. Use the /token-manager slash command to wire it into your existing app.

Operations visibility

Know your infrastructure is healthy. In real time.

Health checks for every service, database stats, active query management, and user admin. Pluggable monitoring with a React dashboard. Python and TypeScript.

Pluggable health checks

Register checks for Postgres, Redis, HTTP services, or anything custom. Built-in factory functions for common infrastructure. One API endpoint returns the health of everything.

Database operations

View commits, rollbacks, cache ratios, and database size. List active queries with duration. Kill runaway queries from the dashboard. Terminate all long-running queries in one click.

One command to install

$ stablestack add-admin-dashboard

Created stablestack_admin_dashboard/monitor.py

Created stablestack_admin_dashboard/models.py

Created stablestack_admin_dashboard/api.py

Created stablestack_admin_dashboard/ui/AdminDashboard.tsx
