Building sh0
The Auditor Caught What the Builder Missed
How independent AI audit sessions found 5 Critical, 12 Important, and 19 Minor issues in 3,200 lines of Rust CLI code -- and why the builder never would have caught them.
Documentation as Product
How we documented 30 CLI commands across a marketing page, dashboard page, and 4 doc pages in 5 languages -- treating documentation as a product feature, not an afterthought.
App Lifecycle From the Terminal
How we built sh0 restart, stop, start, delete, and domains -- five CLI commands for managing application lifecycle with safety-first confirmation patterns.
Watch Mode and WebSocket Streaming
How we built sh0 watch for auto-deploy on file changes and upgraded build log streaming from HTTP polling to WebSocket -- with graceful fallback.
16 Commands in One Day: The Complete CLI Story
How we built 16 CLI commands, 2 server endpoints, and a WebSocket streaming system -- audited through 6 independent sessions -- in a single day of AI-assisted development.
34 Rules to Catch Deployment Mistakes Before They Happen
We built a pure-Rust static analysis engine with 34 rules across 8 categories to catch security issues, misconfigurations, and deployment mistakes before they reach production.
Building an MCP Server: 25 Tools, 3-Tier Safety, OpenAPI-Driven
How we built sh0's MCP server with 25 tools, OpenAPI-driven auto-generation, scoped API keys, risk classification, and confirmation tokens for destructive operations.
Giving sh0 a Brain: AI Gateway with Claude Tool Calling
How we built an AI gateway that lets Claude manage sh0 servers -- with SSE streaming, 10 tool definitions, client-side execution, and a chat UI that feels like talking to a DevOps engineer.
Monitoring and Alerts: Email, Slack, Discord, Telegram, Webhooks
Building a monitoring system with periodic Docker stats collection, threshold-based alert evaluation, and multi-channel dispatch to Email, Slack, Discord, Telegram, and webhooks.
Cron Jobs and Preview Environments: Two Features, Zero Downtime
How we built cron job scheduling with timeout enforcement and preview environments with PR webhook integration -- developed in parallel using git worktree isolation.
14 Days, 105 Sessions, 1 AI CTO: The Complete Story of Building sh0.dev
The complete story of building sh0.dev -- a production-grade PaaS with 488 tests, 119 templates, 25 MCP tools, and an AI assistant -- in 14 days from Abidjan with zero human engineers.
License Enforcement: Free, Pro, Business -- Gating Features in Rust
How we implemented a 3-tier license system in a self-hosted PaaS -- generous free tier, feature gating in Rust, dashboard upgrade prompts, and the pricing decisions behind it.
