Pricing is custom and tailored to enterprise requirements.

Reasonix
Reasonix is an open-source, MIT-licensed coding agent that runs locally and is designed to be left running for hours. It offers one engine with four ways in, a terminal CLI, a desktop app, a browser interface, and an editor integration over ACP. Plan mode holds writes until approved, permissions gate each tool call, and per-turn checkpoints let users rewind a six-hour run without touching git history. Users bring their own DeepSeek API key.

Pollinations
Pollinations is an open-source AI platform with one API for text, image, audio, and video generation, used by 10K weekly active developers. Builders prototype with free Pollen quest credits, integrate via the polli CLI or MCP server, and can earn a share of user spending through App Key earnings. Media uploads, a model catalog, and a community of 500+ live apps round out the platform.

Recall.ai
Recall.ai is the API for meeting recording, giving developers transcripts, recordings, and metadata from Zoom, Google Meet, Microsoft Teams, Webex, GoTo Meeting, and Slack Huddles through one unified API. Products include the Meeting Bot API, Desktop Recording SDK, and Calendar API, with real-time and async data, 100% accurate speaker identification, and a 99.9% SLA trusted by 3000+ customers.

Stably
Stably is an AI-powered web application testing platform that generates Playwright tests from plain-English descriptions. It runs tests in the cloud or your CI pipeline with screenshots, traces, and recordings, then proposes automatic fixes when tests drift. Teams can plan coverage, create test suites, run them, and repair broken tests through a CLI, a visual editor, or a no-code interface. Stably is backed by Y Combinator and also publishes Orca, an open-source agentic IDE.

Void
Void is an open source AI IDE built as a fork of VS Code and backed by Y Combinator. It brings Tab autocomplete, inline Quick Edit, and Chat with Agent, Gather, and normal modes straight into the editor. Void connects directly to any model, private LLMs via Ollama, vLLM, or OpenAI-compatible endpoints, or frontier models like Claude, GPT, Gemini, and Grok, without routing your data through a private backend.
