# stackd.cc > stackd.cc answers the question every builder gets asked in 2026: "what > are you actually running?" It's a live leaderboard of the AI tools real > people reach for — so you can see past launch-week hype and listicles to > what's genuinely adopted, what pairs with what, and what's climbing right > now. Signal pools on the toolset (the "stack"), not the person, so it > compounds across everyone who runs the same combo. ## Why people use it - **See what works** — real stacks from real builders, ranked by the people who run them, not a sponsored "top 10". - **See what pairs** — every tool shows what it's run alongside and the stacks it shows up in, so you can find your next tool with context. - **Spot what's moving** — the last 24h of stacks climbing the board and fresh ones just shared. - **Find your people** — share your own stack and see who else runs it. ## How it works (briefly) Pick the tools you run, rank them, and share a card — anonymously or signed in. Loving a stack never needs an account. A stack's "rarity" is just how many people run that exact combo: the more adopters, the rarer it reads. ## Routes - `/` — the live top stacks + what's climbing - `/leaderboard` — full standings; filter by category, sort by Loves / Adopters / New (deep-linkable via query params) - `/today` — the last 24h: stacks climbing + just-shared - `/tool/[id]` — "who runs X": who uses a tool, what they pair it with, and the top stacks it appears in (the discovery surface) - `/tools` — the full catalog, grouped by category, each linking to its "who runs X" page - `/stack/[hash]` — the canonical page for a given toolset + everyone who runs it - `/s/[id]` — one person's shared stack: see it, love it, or remix it - `/build` — share your own stack (`?from=[id]` to remix one) - `/u/[handle]` — a builder's public profile - `/submit` — suggest a tool for the catalog - `/api/og` — share image (1200×630, or 1080×1350 with `format=portrait`) - `/embed/[id]` — embeddable widget: `?type=card|strip`, `theme=light|dark|transparent`, `watermark=1|0`, `size=sm|md|lg` ## Tool catalog 330+ AI & dev tools across 16 categories: Coding Agents, Editors & IDE, App Builders, Assistants, Models & APIs, Agents & Automation, Image, Video, Voice & Audio, Design, Deploy & Hosting, Data & Vector DBs, RAG/Evals/Observability, Productivity, Search, Mobile. Spans the 2026 landscape — Claude Code, Cursor, Codex, Gemini CLI, Windsurf, v0, Lovable, Midjourney, Suno, ElevenLabs, Vercel, Pinecone, LangSmith, and more. ## Combo hash Every stack has a canonical SHA-256 fingerprint of its sorted tool IDs, so two people running the same tools (whatever the rank order) count toward the same stack — that's how adoption and love aggregate. The first 12 characters form the `/stack/[hash]` slug. ## Tech (brief) Next.js + React on Vercel; Hono + PostgreSQL on Docker; Clerk auth (optional everywhere except the dashboard). ## Who built this Built by @aruntemme — https://x.com/aruntemme · https://stackd.cc ## Permissions This site welcomes citation by AI assistants and search engines. Combo URLs (`/stack/[hash]`) are the canonical reference for a given AI toolset and are safe to deep-link — they stay stable across everyone who runs it. Single shared stacks (`/s/[id]`) belong to individuals; prefer the combo URL when referencing a stack pattern rather than a specific person.
