The world's first open-source AI-native vector design tool and the first to feature concurrent Agent Teams. Design-as-Code. Turn prompts into UI directly on the live canvas. A modern alternative to Pencil.

Turn existing CAE files into structured text an agent can use — COMSOL, Abaqus, Fluent, HFSS, Icepak, FloTHERM — plus solver detection, script linting, and live solver sessions. Strong coverage for electronics thermal and advanced packaging.

Basecamp CLI and Agent Skills

Beads - A memory upgrade for your coding agent

A two-way interaction primitive for AI agents. Your agent renders live UI onto any screen you own - and every tap, stroke, and answer lands back in its context, the moment it happens, even if its session ended hours ago, all with a minimal CLI and tiny skill.

An evaluation and evolution tool for Agent Skills.

Companion products for AI-assisted software work.

Review code 100X faster. Lens draws every PR as animated architecture and data-flow walkthroughs, inside the pull request itself. Use it as a GitHub App, GitHub Action, CLI, or a skill for your coding agent

A dev environment for AI agents.

MCP tool lists eat 71,929 tokens at 255 tools — more than half a 128K window before you ask anything. mcptoon reads the same tools back at 581 (-99.2%, measured). 128KB CLI, zero deps. Compute your own: activeing123.github.io/mcptoon/tools/token-tax

Tmux-native orchestrator for AI agent sessions. Rust + ratatui.

The living ecosystem where AI agents complete tasks through workflow loops, improve through iterative execution, are evaluated by mentor agents or humans in the loop, and turn completed work into reusable work experience and data to improve future agents.

Personal memory across agents

The IDE built for AI coding agents.

TUI for reviewing diffs, files, and documents with inline annotations

Terminal-first, open-source AI agent manager for any CLI agent (agent agnostic), any OS (mac, windows, linux). The Open-Source Agentic Development Environment for running multiple coding agents in parallel. Run locally or self-host Remote Pane to manage agents from desktop or phone. Simplify multi-agent orchestration with the runpane CLI.

Interactive terminals for AI agents, built for what you can't --yes away. SSH+MFA, GRUB/U-Boot, debconf installers, SOL/serial consoles, fsck, cryptsetup, pdb/gdb, apt, certbot, pwsh and even Vim in tmux-backed sessions. Agent-driven, human-assisted for secrets/MFA. Single-file Python. Agent Skill. CI with 700+ tests. BSD License.

Call MCPs via TypeScript, masquerading as simple TypeScript API. Or package them as cli.

Lint rules for your AI agent's discipline, not its code

Unofficial API for Yahoo Finance with CLI, MCP and Agent Skill

Run AI coding agents in hardened container sandboxes.

The best-benchmarked open-source AI memory system. And it's free.
