sh0
Self-hosted deployment. Single binary. Zero complexity.
A deployment platform in a single Rust binary (~2MB). Git push deployments, automatic SSL, built-in AI chat with 20 MCP tools, database management, browser terminal, and multi-server orchestration.
Building sh0
Building a Production Dashboard with Svelte 5 in 48 Hours
How we built sh0's production dashboard -- dark/light themes, 5-language i18n, real-time WebSocket logs, and 7 core pages -- using Svelte 5 runes and TailwindCSS 4 in 48 hours.
From Flat Lists to Stacks: Redesigning Our Entire UX
We threw away our flat app/database list UI and rebuilt around project-scoped stacks with a dual sidebar, context navigation, and cPanel-style sections.
The Deploy Hub: 183 Options, One Page
How we built a Softaculous-style deploy hub with 183 options across 5 categories, 7 deploy form components, and a split-panel UX.
Web Terminal and File Explorer in a Self-Hosted PaaS
How we built a browser-based terminal (xterm.js + WebSocket + Docker exec) and a Docker Desktop-style file explorer -- features most self-hosted PaaS tools lack.
Real-Time Logs: WebSocket Streaming from Docker Containers
How we built real-time log streaming from Docker containers to the browser using WebSocket, with JWT authentication, auto-reconnect, and a terminal-style viewer.
i18n from Day One: 5 Languages Across 105 Sessions
Why we built sh0 with 5-language support from the very first dashboard session, and how we maintained correct orthography across 105 development sessions.
119 One-Click Templates: From WordPress to Ollama
How we built a YAML-based template system with variable substitution, dependency ordering, and 119 production-ready templates covering databases, CMS, AI/ML, and more.
Docker Compose on a PaaS: Parsing, Validating, Deploying
How we added Docker Compose support to sh0 -- parsing Compose v3 YAML, validating dependencies, detecting circular references, and deploying multi-service stacks.
Autoscaling in Rust: CPU Thresholds, Cooldowns, and Load Balancing
How we built horizontal scaling with Caddy load balancing, replica container management, and an autoscaler that evaluates CPU/memory thresholds with configurable cooldowns.
We Audited Our Own Platform and Found 88 Security Issues
We ran 4 comprehensive security audits on our own PaaS and found 88 issues -- 9 critical, 12 high, 45 medium. Here is every finding, every fix, and what we learned.
Migrating from localStorage Tokens to HTTP-Only Cookies
How we migrated sh0's authentication from localStorage JWT tokens to HTTP-only cookies with CSRF double-submit protection -- and why every self-hosted tool should do the same.
From cargo build to a Live Server: The Release Pipeline
How we built sh0's release pipeline: multi-stage Docker builds, cross-compilation challenges, GitHub Actions CI/CD, binary distribution, and the first production deploy.
