DevStash

Live demo: devstash.labnerd.net. Click Try the demo to explore without signing up — it creates a throwaway account that resets hourly.

A centralized developer knowledge hub for storing and searching code snippets, AI prompts, notes, commands, URLs, files, and images — all in one place, instead of scattered across editor snippets, chat history, bookmarks and random text files.

Features

• Seven item types (snippet, prompt, note, command, file, image, URL), plus custom types
• Collections for organizing mixed item types together
• Full-text search across content, tags, titles and types (Postgres to_tsvector)
• Favorites, pinned items, and a "recently used" list
• Command palette (Cmd+K) for fast navigation and item creation (Cmd+N)
• AI features (Anthropic Claude Haiku): auto-tagging, summaries, "explain this code," and prompt optimization
• Rich editing: CodeMirror 6 for code-type items, TipTap for notes, Shiki for syntax-highlighted display views
• File uploads to Cloudflare R2 (images, docs, templates)
• Export to JSON or Markdown
• One-click demo mode — no signup required

Engineering Highlights

• AI endpoints built with an explicit trust boundary. The tag-suggestion and summary actions document their own trade-off in code: any authenticated user can send arbitrary content under the app's shared Anthropic API key, mitigated by a 4000-character truncation on every call. Flagged as acceptable for a single-user deployment with a note to add per-user rate limiting before opening to untrusted users — the kind of limitation that's easy to miss and easy to regret.
• Demo mode is isolated by construction. A reserved demo account (demo@devstash.app) is reset on a fixed interval rather than sharing state with real users, so visitors can explore freely without the data living forever or colliding with anyone else's.
• Full-text search without a search service. Postgres's own to_tsvector/tsquery indexes content, tags, titles and types — no Elasticsearch, no external dependency, for a workload that doesn't need one.
• Three different editors, one consistent experience. CodeMirror 6 (code), TipTap (rich text notes) and Shiki (read-only syntax highlighting) are each the right tool for their item type rather than forcing one editor to do everything.
