1. Skillful
The core mechanic is symlink-based installation: one source folder, linked into Claude Code, Codex, Cursor, Copilot, Gemini CLI, Junie, opencode, or any custom folder target you define. Edit the source and every linked install picks up the change. The docs describe broken-symlink detection and one-click repair, which matters when tools update their config paths and silently drop your workflows. There is no backend, no account, and no telemetry — the library is a folder on your disk, so git is your version control and your backup strategy. Public skill repositories on GitHub can open directly into Skillful's import dialog, which makes trialing shared libraries faster than copying URLs by hand.

2. Wayflow
The vendor describes Wayflow as an embeddable visual workflow editor — canvas, node palette, config panel, run controls, and a runtime engine that executes the same graph in the browser during development and on your server in production. A single call, createWorkflowEditor(), mounts the full workspace. Built-in node types cover LLM calls, tool-calling, branching, map-over-list, and image generation, so AI and deterministic steps sit on the same canvas. Suspend-and-resume is native, meaning a workflow can pause for a human review and pick back up without custom state management. The project is MIT licensed, carries zero runtime dependencies according to the docs, and ships full TypeScript types.

3. Infer0
infer0 sits between your app and the AI provider: users connect their OpenAI, Anthropic, or Google keys, authorize your app via OAuth, and infer0 forwards requests while translating between API formats so your existing SDK calls work unchanged. Your app never touches a key. Spend limits live on the user side, enforced per-provider and per-authorization, revocable in one click. The architecture is passive middleware — no agent logic, no workflow builder — which means it integrates cleanly but covers only the routing and auth layer. If infer0 goes down, your app's requests fail; the docs are explicit: handle that gracefully.
