Kestra

Newagent infraOpen source + enterprise

Kestra is an open-source, event-driven orchestration and scheduling platform where workflows are declared in YAML or built in a no-code editor. It includes an AI Agent task that gives flows an LLM with memory and tools, supports nested agents and the Agent-to-Agent (A2A) protocol, and can expose any flow as a tool to external AI agents through its MCP server. It runs in the cloud, on-prem or air-gapped and is Apache 2.0 licensed.

Discontinued: the open-source VS Code agent with custom modes (architect, code, debug) was shut down on May 15, 2026 and its repo archived; the team now builds Roomote, and roocode.com redirects there. Cline and the community fork ZooCode are the suggested alternatives.

OpenKnowledge

NewproductivityOpen source

OpenKnowledge is a free, local-first markdown editor and knowledge base built for working alongside AI agents. It looks and feels like a Notion-style WYSIWYG editor, with callouts, tabs, Mermaid diagrams and media blocks, but every page stays a plain markdown file on your disk. Coding agents such as Claude Code, Codex, Cursor, Gemini CLI and dozens of others can read and write the same files through its integrations, so specs, team wikis and LLM wikis stay in one place that both people and agents keep up to date. It ships as a desktop app plus a web UI and CLI.

Added Oct 21, 2026
