MLJAR Studio is a private AI data analysis workspace that runs locally, helps users explore data in natural language, generates and runs Python, automates machine learning experiments, and turns notebooks into shareable web apps.

Vennio is an API for scheduling and booking infrastructure. It lets developers and AI agents check real availability, propose times, create bookings, handle calendar integrations, send confirmations, collect payments, and sync to CRMs.

Open-source themed design systems for shadcn/ui, with 29 style variants and one-command installs through a shadcn registry.

Open-source AI coding agent focused on context curation and lower API cost. The repo describes hash-anchored edits, AST-based refactoring, parallel operations, and benchmark results against other agents.

DAC is a dashboard-as-code CLI and framework for building interactive dashboards from YAML and TSX, with a built-in semantic layer and an AI agent workflow for updating dashboards.

Cockpit is a web UI for Claude Code that lets you run and manage sessions from a browser instead of the terminal. It supports multiple concurrent sessions, transcript history, diff and file views, PR review workflows, scheduled runs, and settings for agents, skills, hooks, MCP servers, and CLAUDE.md.

Open-source CLI that runs Codex, Claude, and Gemini in parallel on the same prompt, then synthesizes one answer and surfaces disagreements.

AutoRound is an open-source quantization toolkit for LLMs and VLMs, focused on high-accuracy low-bit inference across CPU, XPU, CUDA, and multiple deployment backends.

Agent Standup is an open-source tool that turns Claude Code sessions into a live stand-up-style view, showing which agents are working, waiting, blocked, or need input. It runs locally and supports VS Code, Cursor/Windsurf/VSCodium, terminals, a desktop app, and status line/tmux setups.

A safety proxy for AI agents that sits between agents and databases, checks SQL before execution, enforces per-agent policies, and supports approvals and rollback of a session’s changes.

A local cloud environment that lets coding agents test Google Cloud-style workflows through MCP, with examples for Cloud Storage, Pub/Sub, and BigQuery. The page includes install steps, agent prompts, runnable commands, diagnostics, and a recorded verification run.

A minimal embeddable coding agent in C with Rust/C extension support, static binaries, and a freestanding design aimed at low footprint and fast startup.

A Claude Code plugin that shows thumbnails for pasted images and opens an editor so you can annotate, crop, rotate, and label images before sending them to Claude.

Codync is an open-source tool for messaging coding agents like Claude Code, Codex, Cursor, Gemini, and others as persistent bots across iPhone, desktop, and terminal. It includes a Rust host, desktop apps, mobile support, approvals, notifications, and remote access features.

A reputation layer for AI agents that tracks verified tasks, trust scores, and weekly leaderboards, with a CLI to register and run agents.

Deterministic gates for coding agents that block risky or pointless actions with code-based checks. The repo shows hook-based controls for delete protection, git safety, egress blocking, credential access, install pinning, loop detection, and idle-process handling across Claude Code, OpenAI Codex, and Antigravity.

Octri turns an OpenAPI spec into docs, SDKs in 10 languages, an MCP server, and monitoring tied to generated SDKs.

Black-box security and contract testing for MCP servers, with baseline diffing, CI failure policies, and report output for JSON, JUnit, and SARIF.

Enterprise Postgres platform for AI apps, with managed, BYO cloud, and on-prem deployment options. It adds built-in MCP access for agents, pgvector and hybrid search for RAG, branching for isolated experiments, and a path from prototype to production.

Sandboxed macOS VMs with full Xcode for AI coding agents, plus a lightweight Linux container mode. The repo describes isolated agent execution, egress allowlisting, and support for running Xcode and iOS Simulator workflows unattended.

Open-source multi-agent harness for generating manufacturable CAD from plain-English briefs or sketches, using LLM agents, CadQuery Python code, renders, and DFMA checks.

A CLI and plugin bundle for AI agents to schedule social media posts through Postiz. It includes integrations for Claude Code, Cursor, Gemini CLI, Qwen Code, and DeepSeek Harness, plus support for the hosted Postiz MCP server.

A macOS menu bar app that shows Claude Code and Codex usage limits, reset timing, and usage status with native notifications and optional exact reset times.

A Python library for agent evals and guardrails that uses typed decision questions instead of an LLM judge. It supports one-request evaluation for traces, with examples for tool choice, grounding, relevancy, and injection checks.
