About This Site
Open-source integration infrastructure for AI agents and third-party applications Corsair is an open-source integration layer for AI agents and applications. It provides secure, multi-tenant OAuth authentication, permissions, MCP support, webhooks, credential management, caching, and provider-specific error handling for services such as Gmail, Slack, Notion, HubSpot, Airtable, Google Calendar, Stripe, Linear, GitHub, and Discord. Developers can self-host the SDK for free or use Corsair's managed cloud platform to connect third-party applications without maintaining authentication flows, token rotation, webhook verification, API changes, rate-limit handling, and tenant credential isolation.

[Embedditor]
Open-source editor for vector LLM embeddings to improve search and reduce costs.
Embedditor is an open-source Editor of vector LLM embeddings, which enables users to create impressive search results, improve performance of vector search, and save up to 30% on embedding and vector storage with the Simplicity of MS Word. It helps you get the most out of your vector search by improving embedding metadata and tokens with a user-friendly UI. Seamlessly apply advanced NLP cleansing techniques like TF-IDF, normalize, and enrich your embedding tokens, improving efficiency and accuracy in your LLM-related applications. Optimize the relevance of the content you get back from a vector database, intelligently splitting or merging the content based on its structure and adding void or hidden tokens, making chunks even more semantically coherent. Get full control over your data by deploying Embedditor locally or in your dedicated enterprise environment. Reduce costs by filtering out irrelevant tokens, saving up to 40% on embedding and vector storage.

AI video generation for agents: 200+ models, one key
varg is the AI video platform for agents and developers. One API key and one MCP server (mcp.varg.ai) reach 200+ models: text- and image-to-video on Seedance 2.5, Kling 4, Veo 3.1 and Wan 3; images on Nano Banana 2.1, GPT Image 2.5 and Flux 3; ElevenLabs v4 voices, lip sync, talking avatars, music, captions and multi-scene renders to MP4. Every model is billed at provider price with no markup (1 credit = $0.01). Agents in Claude Code, Codex and Cursor drive it through the varg MCP and open-source agent skills, and varg how to (varg.ai/how-to) tells any agent which video skill to use for a request, free and without a key
