Nimbalyst is a visual workspace for building with Codex, Claude Code, and other coding agents. It combines collaborative editors, session management, task tracking, git/worktree tools, and a mobile app for managing agent work on the go.

An AI model gateway for builders offering 35+ models through a single OpenAI-compatible API, with instant API key delivery and pay-as-you-go credits starting at €1.

A non-custodial on-chain bond platform that lets AI agents raise capital, issue debt, and repay lenders directly from the chain. It includes a CLI/SDK, live Base mainnet support, testnet funding, and open-source docs and contracts.

A small Linux CLI for running coding agents in a sandboxed environment. The repository shows installation options, TOML-based configuration, supported agents, and troubleshooting notes.

An open-source, self-hostable customer platform built for the agentic era, with MCP-first tooling for knowledge base, conversations, CRM, CMS, outreach, and analytics. The README shows concrete modules, data portability, and self-host setup instructions.

A local-first Python tool that audits Git history to quantify rework in AI-generated engineering work, including PR correction rates, churn clusters, superseded work, and line survival.

A Python CLI that packages data science repositories and data-heavy project files into LLM-friendly prompts, with sampling for CSV, SQL, Excel, and notebooks.

A visual editor for React apps that lets you edit UI live and writes the changes back into source files. It runs locally as a proxy/overlay and supports Next.js, Vite, and Create React App.

Git-native memory for coding agents that stores repo intent, decisions, constraints, and review context before the diff. The repo includes the problem statement, product positioning, install steps, and agent hooks for tools like Claude Code, Cursor, and Codex.

Open-source multi-modal Claude Code client that runs locally and lets Claude compose across plugins, GUIs, documents, charts, wikis, automations, and messaging bridges.

A loadable SQLite extension that adds column-oriented storage and analytics for fast local OLAP-style queries, with benchmark data and build instructions.

Semble is a local-first code search tool for agents. It offers natural-language search, an MCP server, bash/AGENTS.md integration, and a Python API, with claims of faster indexing and much lower token usage than grep+read.

A CLI for the Slack Web API built for coding agents. It exposes Slack methods through a single command format, supports JSON stdin, dry runs, pagination, and discovery commands, and installs via npm.

Harness is an agentic IDE for running coding agents on remote machines over SSH, with one-click backend setup, backend switching, web access, and notifications across machines.

A CLI-based mailbox and message bus for AI agents, with backends for GitHub, SQLite, S3, GCS, Postgres, and local storage. The repo also includes plugin support for Claude Code, Codex, and OpenCode.

An interactive site showcasing short AI-built arcade games and a model bench that compares coding models across the same tiny game constraints.

ClaudeLines is a registry for Claude Code status line scripts, letting users browse community-built bars and install them with a single prompt.

A local CLI for replaying what AI coding agents accessed on your machine, including file reads, secrets that entered context, and possible read-then-network-call exposure paths. It also scans exported ChatGPT, Claude, and Gemini histories for sensitive data.

A zero-dependency TypeScript music theory engine with scale, mode, key, and interval utilities, plus MCP server support for AI assistants.

A local terminal UI for exploring AI coding spend across tools like OpenCode, Claude Code, Codex, GitHub Copilot, and more. It shows costs by month, day, project, session, and model, with drill-down views, heatmaps, exports, and a web browser mode.

Open-source runtime for coding agents that sits underneath Claude Code to reduce tool calls, shorten context, and track savings. The page includes installation steps, a local savings check, and benchmark results comparing cost and performance.

A free open-source Mac app that lets non-coders enable and manage Claude Cowork skills and personas through a switchboard-style UI.
