What is OpenAdapter?

OpenAdapter is a multi-provider AI gateway for developers, sold as a fixed-price subscription rather than metered per-token billing.

The problem. A developer building with AI today juggles several accounts and keys — one for models, one for a vector database, one for web search, one for OCR — each with its own bill, its own rate limits, and its own outage. Costs are unpredictable and switching models means reconfiguring everything.

What OpenAdapter does. You get a single API key that works anywhere the OpenAI or Anthropic API works. It routes requests across 40+ open-source models — DeepSeek, Qwen and Qwen-Coder, Kimi K2.5, GLM-5, MiniMax, Mistral, Meta Llama, with new models added on a rolling basis — and bundles the surrounding toolkit: web search, URL scraping, OCR, image understanding, audio (STT/TTS), embeddings, a vector database for RAG, and a one-click MCP server store for agentic editors.

Where it works. Any tool that accepts a custom base URL: Cursor, VS Code (Cline, Continue, Roo Code), Windsurf, Claude Code, Aider, Zed, OpenCode, PearAI. As an API, any app or script that speaks the OpenAI format — swap the base URL, nothing else changes.

Pricing. Free tier with a daily quota and no card. Paid plans from $6.99/mo. Request- based with rolling 5-hour, weekly and monthly windows, so cost is predictable.

Key features (bullet format — most directories ask for 3-8) 40+ open-source models through one OpenAI-compatible endpoint Flat subscription, request-based — no per-token billing or surprise invoices Two endpoints: OpenAI-compatible /v1 and Anthropic Messages /v1/messages Built-in toolkit: web search, URL scraping, OCR, vision, audio, embeddings Vector database included for RAG — collections, upsert, similarity search MCP store: one-click Model Context Protocol servers for agentic editors Works in Cursor, VS Code, Claude Code, Windsurf, Aider, Zed and any custom base URL tool Private models in a trusted execution environment (TEE) — prompts stay on our hardware No vendor lock-in: OpenAI-compatible, so you can swap out any time
