- [TinyFish](https://leyline.ahensya.com/components/tinyfish.md): Search, fetch, and browser automation for agents. Free Search and Fetch; metered browser runs. Leyline uses it as intake evidence crawl, not as a locked vendor.
- [Playwright](https://leyline.ahensya.com/components/playwright.md): Browser automation for tests and agents. Use the browser slice without taking the whole test-runner product box.
- [n8n](https://leyline.ahensya.com/components/n8n.md): Workflow automation. Compose and schedule slices that agents can call without owning the whole iPaaS.
- [Needle 3](https://leyline.ahensya.com/components/needle-3.md): Needle 3 is Cactus Compute’s on-device “automation foundation model”: a laddered / sliceable tiny model (post: 8–29 MB CQ2-bit binary; 25–121M params; depths 2–20 layers from one weight set) built on their Simple Attention Networks, aimed at tool calls, structured extraction, and local text embeddings — not open-ended chat.
