Craft Agents is a tool we built so that we (at craft.do) can work effectively with agents. It enables intuitive multitasking, no-fluff connection to any API or Service, sharing sessions, and a more document (vs code) centric workflow - in a beautiful and fluid UI.
It uses the Claude Agent SDK and the Pi SDK side by side—building on what we found great and improving areas where we've desired improvements.
An open source design system that's fully customizable and agent ready.
An open source design system that's fully customizable and built for how we build now — by people and the agents working alongside them.
It ships 150+ accessible components, brand-level theming, dark mode, ready-to-ship templates, and a CLI as one cohesive system. You import pre-built CSS and use typed React components — no build plugin, no styling library to adopt — and both people and AI assistants build with the same tooling.
Multi-Agent Orchestration for AI Agents. An AI agent swarm that compounds daily.
Build an agent swarm for Claude Code and AI agents: a lead coordinates tasks, workers ship in their own containers, memory compounds with every run. Interact as you do with your remote colleagues.
The Collaboration Layer For AI Agents
One live, auditable state, shared by every agent working together.
When an agent and a person change the same thing at once, work gets lost: one edit silently clobbers another, or the agent acts on data that already moved. Ablo gives them one shared, typed write path so people, server actions, and agents can all work on the same rows without working blind.
OKF is a universal, vendor-neutral format for representing knowledge as plain markdown files with YAML frontmatter. It is not tied to any particular agent, framework, model provider, or serving system.

A tool for transforming and moving code between repositories.
Copybara is a tool used internally at Google. It transforms and moves code between repositories.
Often, source code needs to exist in multiple repositories, and Copybara allows you to transform and move source code between these repositories. A common case is a project that involves maintaining a confidential repository and a public repository in sync.
Copybara requires you to choose one of the repositories to be the authoritative repository, so that there is always one source of truth. However, the tool allows contributions to any repository, and any repository can be used to cut a release.
Semantic DataFrames for humans and agents.
fenic turns AI-assisted exploration of structured and unstructured data into reusable, inspectable DataFrame pipelines.
It's a DataFrame query engine for semantic data processing, with AI operators — extract, classify, summarize, embed, semantic join, and more — built into the query model. Use it to turn documents, transcripts, logs, eval traces, tickets, tables, and APIs into typed rows and repeatable workflows.
