Gnoseed is a free spaced-repetition flashcard platform for developers, focused on Kubernetes, DevOps, AI, cloud, and certification prep. It includes 3,924+ practice questions, 47 topic decks, offline use, and learning paths for roles and exams.

A verification browser for AI coding agents built on WebKitGTK, aimed at fast visual checks, page assertions, and human handoff. The repository shows install steps, CLI usage, MCP support, and a concrete agent workflow.

An SSH client built for AI agents and humans. Corv focuses on named connections, warm authenticated sessions, structured JSON output, and safer command execution for agent-driven infrastructure.

Open-source desktop disk cleaner for developers and machine learning engineers on macOS and Windows. It detects and removes caches from tools like Hugging Face, Ollama, npm, pip, conda, Docker, and IDEs, with safety ratings and restore-friendly cleanup.

Stele is a hosted shared memory layer for AI coding agents. It keeps decisions, tasks, lessons, and risks in a project graph that Claude Code, Cursor, Codex, and other MCP-compatible tools can read and write.

Millwright is a self-hosted Rust LLM router that sits between apps and model providers to enforce policy-based routing, control spend, and preserve provider/model affinity for cache reuse.

A local proxy and CLI for switching and monitoring Codex and Claude Code accounts, with combined token-throughput analytics and rate-limit awareness.

Fractal is a developer tool for running hierarchical agent loops that break complex work into sub-tasks, spin up child nodes in git worktrees, and track state locally in SQLite with a terminal UI.

Self-hosted OpenAI-compatible AI gateway with a CLI, server mode, and web UI for text, image, and audio workflows across many models and providers.

An MCP server for GoCD that lets AI agents inspect and operate pipelines using per-user GoCD personal access tokens. It exposes read, action, and destructive toolsets, plus resource URIs for dashboard, agents, and pipeline data.

A local-first CLI that compresses application logs into a token-optimized Markdown/JSONL summary for LLMs.

Self-hosted Hacker News reader that summarizes top stories with AI, translates them into 20+ languages, personalizes the feed, and sends a daily briefing to Telegram.

Local-first MCP gateway that lets multiple AI clients share one server setup, with lazy tool discovery to reduce token usage and built-in tool integrity and quarantine controls.

Fuse is an open-source .NET MCP/CLI tool that helps coding agents work on C# codebases with Roslyn-backed indexing, dependency injection and route resolution, scoped context reduction, and compiler checks before edits are written.

Agentty is a terminal-based AI pair programming tool and a drop-in alternative to Claude Code, built as a single static C++26 binary with support for multiple model providers. The repository shows installation paths, provider examples, sandboxing, air-gapped mode, and integration with Zed via ACP.

A command guard for AI coding agents that blocks destructive git and shell commands before they run, with support for multiple agent and CLI tools.

A Mac-native menu bar app that tracks AI token usage, shows spend by model, and pops up break reminders when usage crosses configurable thresholds.

A macOS utility for customizing the native Slack app by injecting CSS and JavaScript, hiding Slackbot, upsells, tabs, and other UI elements in real time.

Blocks.ai is an infrastructure and network layer for AI agents, offering outbound-only connectivity, routing, auth, billing, streaming, and a marketplace/network for builders and callers.

A CLI BI tool built for Claude Code that lets agents connect to data sources, generate live dashboards, publish shareable links, and even write back to connected systems.

A macOS app for browsing, searching, and resuming local history from coding agents like Codex, Claude, Cursor, OpenCode, Copilot, Pi, and Antigravity. It also adds transcript views, image browsing, analytics, and a live quota meter for Codex/Claude usage.

Nicasa is a native macOS image viewer and Chrome extension for fast image browsing, with AI image enhancement, smart image extraction, screenshot capture, and local-only processing.

Abralo is a native desktop app for running multiple Claude Code agents at once in one window. It focuses on keeping several agents visible, showing token usage, and surfacing when an agent needs attention.

Local CLI for analyzing when a coding agent starts degrading as session context fills, using transcript data already stored on disk.
