Open-source Jina AI alternatives

Wigolo is a local-first web access layer for AI agents. It exposes search, page fetching, crawling and research capabilities over the Model Context Protocol, so a coding agent can look things up on the web without you buying a search API key or sending queries through a metered cloud service.

The README says it works with a long list of clients, including Claude Code, Cursor, Codex and Gemini CLI as well as OpenCode, Windsurf, Zed and VS Code, and with frameworks such as LangChain, CrewAI, LlamaIndex, the Vercel AI SDK and n8n, plus any MCP client or plain REST. Repository topics describe it as a metasearch and web crawler and name Exa, Firecrawl and Tavily as the services it stands in for. The project is in public beta.

Wigolo is written in TypeScript and its license is listed as 'Other' on GitHub, so read the licensing section before commercial use. It runs on your own machine. It suits developers who want agent-ready web search that is private and free of per-query costs.

Trieve is an all-in-one platform that exposes search, recommendations, retrieval-augmented generation (RAG) and analytics through an API. Developers upload content as chunks and then query it with semantic, keyword or hybrid search, without assembling the vector database, embedding and reranking pieces themselves.

Its search features include dense vector search with OpenAI or Jina embeddings stored in Qdrant, typo-tolerant neural sparse search, sub-sentence highlighting, recency biasing, merchandising controls and hybrid search with cross-encoder reranking. A recommendations API finds similar chunks or files, and RAG routes use OpenRouter so you can pick the language model. You can also plug in your own embedding, reranking and LLM models.

Trieve can be self-hosted in your VPC or on-premises, with guides for AWS, GCP, Kubernetes and Docker Compose, and it also offers a hosted sign-up with a free allowance of 1,000 chunks. The backend is Rust with Actix and Diesel on PostgreSQL, with a SolidJS front end, an OpenAPI specification and TypeScript and Python SDKs. It is released under the MIT licence.
