by es617 - An outstanding, creative library that converts Claude Code session transcripts into self-contained, embeddable HTML replays - interactive playback with speed control, a local editor, collapsible tool-call and thinking blocks, redaction for private information - the output is fantastic. Also supports other providers

A website where you can compare every AI Model ✨

Drop-in governance layer for AI coding tools. Backlog-first delivery, cross-session memory, decision tracking, QA gates, and autonomous delivery daemon. Works with Claude Code, Cursor, Codex CLI, Gemini CLI, Windsurf. Markdown + YAML + bash, zero dependencies

by S.F. Kislev - A tiny bridge that lets Claude Code drive desktop software — Photoshop, Premiere, Blender, Unity, InDesign, Office, 13 apps total — by writing one-time scripts against each app's own automation runtime (COM / AppleScript / CEP), instead of MCP servers or fragile screenshot-based computer use. A genuinely novel approach that unlocks the apps' full scripting surfaces (InDesign alone

Windows app that reads, searches and backs up your Gemini CLI chats across accounts, and continues any chat in Gemini CLI through a handoff file that carries the whole conversation

Sync Skills, MCP servers, Agents & Commands across Claude Code, Cursor, OpenCode, Codex, and Gemini CLI with automatic format conversion (JSON ↔ TOML ↔ JSONC)

Self-hosted web app that turns one set of AI coding rules into the file each tool reads: Gemini CLI's GEMINI.md, AGENTS.md, CLAUDE.md, Cursor rules and Copilot instructions, 30 rule-file formats in all. Blueprints carry variables so a team shares one set across projects, and the lynxp CLI writes the files into each repository. AGPL-3.0

AI agent skill that analyzes git history to reveal codebase hotspots, bug magnets, bus factor risks, and development momentum before reading any code. Works with Gemini CLI, Claude Code, Cursor, and 20+ other coding agents

by Amin Dhouib (Devino Solutions) - A zero-dependency, cross-platform notifier that fires a desktop toast and a free phone push (via ntfy) the moment Claude Code (or Codex/Cursor/Gemini) finishes a task or needs input, wired up by a one-command setup. The standout among notifiers is its testing rigor — CI drives the *real* agent CLIs end to end and asserts real ntfy round-trips and real OS toast d

Local guardrail with a BeforeTool hook for Gemini CLI (laya-guard install gemini-cli) that judges each shell command before it runs, using regex rules, protected paths, and a small on-device model. Blocked commands are denied; ones marked for review pass with a note. Also hooks into Claude Code, Codex, Cursor, and other agents. MIT

Self-hosted mesh router for local LLM backends — OpenAI /v1 + Anthropic Messages on :11400, mDNS LAN peers. Complements cloud gateways with local LAN mesh for Cursor, Claude Code, Codex, and Honcho

Dashboard and macOS menu bar for tracking AI subscription quotas in one place (Claude Code, Codex, Gemini CLI, GitHub Copilot, and Cursor). Supports multi-accounts, notifications, and session-timer start optimization

Local-only TUI + web dashboard that tails Gemini CLI sessions alongside Claude Code, Codex, Cursor, Hermes, and OpenClaw on one unified timeline. Parses tokens, tools, and per-turn cost from each Gemini CLI session (gemini-2.5-pro / flash rates), plus context compaction visualizer, MAD z-score anomaly detection, MCP server mode, and OpenTelemetry exporter. No cloud, no telemetry. macOS + Linux. MI

Browse and monitor historical session records of AI programming tools (Claude Code, Codex CLI, Cursor, Aider)

Leads every response with a three-line TL;DR and folds the full detail underneath, so the answer is not buried. Never folds destructive commands, security findings, verbatim errors or diffs. Returns a parseable block for agent-to-agent reports. Ships a Gemini CLI extension

Generate AI coding rules from your actual codebase using Google Gemini. Feeds source files into Gemini's 1M token context window and produces project-specific rules. Supports Cursor (.mdc), Claude Code (CLAUDE.md), Copilot, and Windsurf output formats. Zero dependencies

Zero-dependency Go CLI / package manager that installs Agent Skills and MCP servers into Gemini CLI (and other tools), plus Claude Code slash commands and hooks

Finds API keys in the chats, logs and checkpoints Gemini CLI keeps under ~/.gemini/tmp and in the MCP servers of ~/.gemini/settings.json, redacts them in place, and installs BeforeAgent / BeforeTool / SessionEnd hooks (spillage guard install) that block a prompt with a key in it and reads of .env. Python, no dependencies, no network; also covers Claude Code, Codex CLI and Cursor

Local policy layer with a BeforeTool hook for Gemini CLI (openmoat init) that checks every shell command, file read and write, web request and MCP call against one policy before it runs, blocking what the policy denies. Adds an egress proxy, MCP server pinning and a hash-chained audit log, and the same policy covers Claude Code, Codex, Cursor and other agents. Rust, MIT OR Apache-2.0

Agent Skill for frontend and document design (typography, palettes, 30 templates, offline design checks) with setup instructions for Gemini CLI

Turns a Gemini CLI chat from ~/.gemini/tmp/*/chats (the JSONL format with rewinds and patches, or the older JSON files) into a self-contained HTML replay with a scrubbable timeline, diffs and terminal output, with API keys and other secrets masked locally first. Share it as a link through a secret gist on your own GitHub, embed it, export a Markdown transcript for a pull request, or have its GitHu

Gemini CLI hooks (BeforeTool/AfterTool) that learn from failed tool calls by themselves and stop a known mistake before it runs; what one agent learns protects your other agents (Claude Code, Codex, Cursor, OpenCode and more)
