Multica is an open-source platform that treats AI coding agents as first-class team members rather than background tools. You assign issues from a project board to an agent the same way you'd assign to a colleague — it claims the task, executes autonomously, reports blockers, and updates status in real time via WebSocket. The killer feature is skill compounding. Solutions get codified as reusable 'skills' — packages of code, config, and context. One agent solving a tricky migration problem means every future agent invocation can draw on that knowledge. It's a flywheel that makes your agent fleet smarter with every task completed. Multica supports Claude Code, Codex, OpenClaw, OpenCode, Hermes, Gemini, and Cursor Agent backends with auto-detection. The stack is Next.js 16 frontend, Go backend, PostgreSQL + pgvector — self-hostable with Docker or available as a managed cloud. It hit 14k stars in its first week of trending, making it one of the fastest-growing agent infrastructure projects right now.

Windmill turns scripts into workflows, UIs, and scheduled jobs. Write in TypeScript, Python, Go, or SQL and get auto-generated UIs with approval flows.
Reviewer scorecard
“This is what I've been hacking together manually — a dashboard where I can assign GitHub issues to a Claude Code agent and watch it work. Multica packages that into an open-source platform with WebSocket updates, skill reuse, and multi-agent support. The auto-detection of Claude Code, Codex, OpenClaw, and OpenCode backends means I don't rewrite infra when I switch models.”
“Scripts become workflows with auto-generated UIs. The approval flows and scheduling turn scripts into proper automation.”
“The premise — agents as teammates on a project board — is compelling, but the execution requires buying in to a full Next.js + Go + PostgreSQL stack just to manage what is essentially a task queue with a pretty UI. Compound skills sound great until your agent codes itself into a corner with accumulated context from previous runs. Early days; wait for the 1.0 with battle-tested error recovery before putting this in production.”
“Open-source Retool + n8n hybrid. The auto-generated UI from script parameters is surprisingly useful.”
“Multica represents the transition from 'AI tool you use' to 'AI colleague you manage.' The skill compounding model — where one agent's solution becomes a reusable capability for the whole team — is the flywheel that makes AI teams smarter over time. We're watching the org chart change in real time. 10k+ stars in a week is a strong signal the market agrees.”
“Internal tooling from scripts with auto-generated UIs is the right abstraction for developer-built automation.”
“As a solo creator running content pipelines, having agents show up in my task board alongside my actual work — rather than in some separate AI tool tab — removes a lot of mental overhead. The skill reuse feature means I build a 'draft blog post from research notes' skill once and every future agent invocation benefits from it.”
