Vectorless EngineChunking a document destroys the thing that made it readable. This parses a document into a tree and lets a model navigate it, returning whole sections with citations.Vectorless SDKThe same engine from TypeScript or Python. No chunking, no top-K, no vector database — and every choice it makes is traceable.LLMGateLiteLLM for Go. It was the gateway the engine depended on, so I pulled it out into its own module — router, fallback, cost tracking and capability flags over Anthropic, OpenAI and Gemini.PDFGrabParse the page, find the tables, and keep the coordinates of every glyph — so when a page is rasterised the answer can be highlighted exactly where it was found. That last part is why it exists: it is what turns a citation into something you can see.Context8Context7 gives an agent the docs. This gives it what the docs do not cover — every uncommon error an agent solved used to vanish with the session. Local-first: SQLite and sqlite-vec, no daemon.SwarmTorch120 metaheuristic optimisers as drop-in torch.optim subclasses — 60 that train weights without gradients, 60 that search hyperparameters — with the population evaluated in one batched pass on the GPU.YarnGPT SDKText to speech in Nigerian accents, 16 voices, and the API had no Python client. Typed, async, with a CLI.YouTube TranscriptA faithful TypeScript port of youtube-transcript-api. It calls the same internal player endpoint rather than scraping the page, so it does not break when the DOM changes. Node, Bun and Deno.Vectorless MCPSo an agent can reach the retrieval engine as a tool. I write the MCP servers, not just consume them.
Every version number here is one you can install.
Nothing on this page is a private repository or a plan. Each row links to the registry or the source, and the version shown is the one published there.
