Three pillars · One workspace
The full journey from curious to production-ready.
Every AI persona enters somewhere on the curve — hobbyist, developer, or architect. LLMAtlas meets you where you are and pulls you forward.
What's inside
Every tool you need. Zero you don't.
A fully integrated workspace — not a collection of tabs. Everything talks to everything.
Multi-model playground
Stream responses from DeepSeek V4 Pro, Claude Opus 4, Kimi K2.6, Qwen 3.6, Gemini 2.5 and more — temperature, top-p, and system prompts all tunable.
3-model compare lab
Fire the same prompt at up to 3 models in parallel. Instant tok/s, TTFT, and quality diff — pick the right model for the job.
Cost calculator
Project monthly LLM spend for any workload. Compare 195+ free models against 15 paid anchors (GPT-4.1, Claude Opus 4, Gemini 2.5…).
Live API status
Real-time uptime and latency for every major provider. Auto-refreshes every 30 seconds. Bookmark it for the next outage.
Public leaderboard
Multi-axis composite ranking — Quality, Speed, Context, Openness, Value. Sortable table + radar chart. Filter by capability.
Prompt library
Save, tag, version, and search prompts. Accessible anywhere in the app. Stored locally — your prompts never leave your browser.
BYOK — bring your own key
Use the free server-side keys out of the box, or plug in your own for higher limits. Keys stored client-side only — never sent to us.
Streaming everywhere
Token-by-token streaming on every model, every feature. No polling, no waiting for full responses. Tight latency budgets respected.
Reasoning models supported
DeepSeek R1, QwQ, o3 — thinking-mode models with extended chain-of-thought. Collapsible reasoning traces in the playground.
Edge & ultra-fast inference
Cerebras wafer-scale and Groq LPU models serve 800+ tok/s. Cloudflare edge nodes guarantee sub-100ms TTFT globally.
Privacy & security
No analytics by default. Keys never leave your browser. Self-host in minutes on Vercel, Cloudflare Pages, or your own server.
100% open-source
Built on Next.js 15, Tailwind CSS, shadcn/ui, Zustand, and Recharts. Fork it, deploy it, white-label it — MIT license.
Open-source-first pricing
Free until you scale.
Then absurdly cheap.
Every tier rides on free-tier APIs. Premium upgrades unlock only the tooling you can't build yourself.
