31,000 Translations in One Session: How We Made sh0.dev Speak 5 Languages with 40 AI Agents
We translated our entire 120-page SvelteKit website into 5 languages in a single Claude Code session using 40 parallel agents. Here's the architecture, the failures, and the methodology.
The Deploy That Broke Itself: How 2 Simultaneous Deploys Exposed 8 Concurrency Bugs
Two simultaneous deploys crashed sh0's pipeline. We found 8 concurrency bugs across 3 audit rounds. Here's everything we learned about async Rust, Docker race conditions, and why AI auditors catch what AI builders miss.
SH0.DEV MCP: When Your AI Has 30 Tools But Can Only See 15
How we discovered half our AI's tools were invisible, why it happened, and the MCP-first architecture that fixed it permanently.
The Backup Engine That Never Backed Up
We built a complete backup engine with 13 storage providers and AES-256 encryption. Then we clicked "Backup Now" and nothing happened. Here is everything that was broken.
Docker Volumes Are Not Host Paths
Volume backup failed because we tried to tar a path on the host filesystem. Docker volumes live inside containers -- here is how the Docker archive API fixes it.
When pg_dump Cannot Find Your Database
pg_dump failed with "database flin-postgres does not exist" because the backup engine used the app name instead of POSTGRES_DB. Here is the env var decryption pipeline that fixed it.
The UI That Looked Complete
The backup dashboard had modals, CronBuilder, 3-step wizards, and a schedule table. Everything looked finished. Nothing worked. Here is what we fixed.
Why I Built My Own AI Helpdesk Instead of Paying for One
Why I built an AI-powered live chat widget for sh0.dev instead of paying $50/month for Intercom -- and how it costs $0.002 per conversation.
Two Critical Bugs in a Public AI Widget
How two independent audit sessions found an XSS vulnerability and a billing bypass in a public-facing AI helpdesk widget -- and why the builder missed both.
From Docs Chatbot to Live Support Agent
How we turned sh0's existing AI docs assistant into a public helpdesk widget with 9 files, zero new infrastructure, and the same SSE streaming pipeline.
From 10 Commands to 30: The Developer Ergonomics Sprint
How we added sh0 init, link, open, and config -- four commands that make the sh0 CLI feel like a native part of the developer's workflow, not an afterthought.
One Command to Deploy: How We Built sh0 push
How we built sh0 push -- a single command that detects your stack, packages files, uploads, builds, and returns a live URL in under 40 seconds.
