Hotseat is a free, open-source macOS menu bar app that moves Claude Code and Claude Desktop to another of the user's Claude accounts in one click and returns to the same session. Sessions, settings, skills and MCP servers are shared, so `claude --resume` works under either account. When a session hits a usage limit, it offers to continue under another account. It never reads tokens or cookies. Install with Homebrew.

Chums is a free, open-source Apple Watch app that turns Claude Code and Codex sessions running on a Mac into animated characters, in the spirit of Muse Charm. Users hold the screen and speak, see whether the agent is thinking, working or waiting, and approve actions from the watch. Each character has its own session, personality and voice. The iPhone companion app adds photos, files and interactive results. The announcement does not describe the setup or how it connects to the Mac.

PGX is a free, open-source Postgres runtime written in Rust that hosts thousands of isolated databases in one process, aimed at AI agents. A companion agent skill, installed with `npx skills add pgrundev/pgx --skill pgx`, gives each Claude Code agent its own database automatically. The author claims 1,000 databases in 659 MB RAM, about 0.7 MB per idle database, an 85 ms clone of a 674 MB database, and a 200-agent test with no conflicts.

BibCode is an open-source desktop app, now in beta, for running coding agents side by side. It is built with Rust and Tauri rather than Electron, and runs Codex, Claude, Cursor and OpenCode, each in its own git worktree. It can also connect to remote BibCode Servers. The author, Mauro Ubeda, says it mixes ideas from T3 Code and Orca. The post gives no feature detail beyond this.

Routing plans judge each new message and send routine work to economical models, while harder design decisions and fixes stay on the primary model. It supports custom task branches, ordered failover candidates with explicit exhaustion, per-session cost and usage records, and runs as a macOS desktop app or a Linux CLI and daemon.

decomp.wtf is an open-source (MIT) local workspace where AI coding agents decompile games into C, one function at a time. Agents receive assembly, data, callers and earlier attempt notes, then each C candidate is compiled with the game's original compiler, linked at its real address and compared byte for byte, with instruction diffs on misses. It exposes MCP tools for Claude Code, Codex, Antigravity CLI and opencode, plus a live view of agent calls and match scores.

Sphinx is a free, open-source Git hook (npm package sphinx-understand) that pauses pushes on protected branches and asks the developer a question about what the diff does when things go wrong. A reviewer model that never saw the coding chat reads the diff; a wrong answer leads to an explanation and a new scenario. It works with Codex, Claude Code, Cursor, OpenCode and Pi, or plain Git. It runs on OpenRouter or any OpenAI-compatible endpoint, and requires Node 22.19+.

A tweet promoting Coucou, an open-source app (about 5,000 GitHub stars, per the post) that monitors Claude Code sessions from the iPhone Dynamic Island. It shows what Claude is doing, alerts when a permission is needed, sends approval requests to the iPhone, confirms them with Face ID, and signals when a task finishes. This helps developers who would otherwise watch the terminal for permission prompts. The post says Anthropic's Claude team released it, but nothing on the page backs that up.

It translates between the OpenAI Chat, OpenAI Responses, Anthropic Messages and Gemini APIs. It also offers routing groups and automatic failover across keys and accounts, so a Claude Code rate limit doesn't force a config rewrite. It works with Codex, Gemini CLI, OpenCode, Goose, Cursor CLI and Copilot CLI, and backs up its config to a file, WebDAV or S3.

Show HN: Parsimony – an open-source benchmark for how much code AI models add

Parsimony is an open-source benchmark that ranks AI coding models by how much code their patches add. It parses the patches already published by benchmarks such as SWE-bench Verified, counts syntax-level "coding units" (statements, calls, comparisons, names, literals) rather than lines, and subtracts deleted code to get net units. It adds a leaderboard, an Artificial Analysis Intelligence Index overlay, the author's own DeepSWE runs, and a way to upload your own results. It matters because existing benchmarks score solve rate and cost but not code bloat, which makes codebases harder to maintain. The page states its limits: it measures size, not quality, and more verbose models tend to solve more tasks.

PDF TO MP3 is a hosted MCP server (Streamable HTTP, account authentication) that turns PDFs into audiobooks. The user's existing AI subscription, such as Codex, handles document processing through the MCP connection. Speech generation is billed separately through the user's own OpenAI or Google text-to-speech API key. The setup is three steps: add the MCP server, add a speech key, then attach a PDF and ask the assistant to use the MCP. It shows a "bring your own subscription" pattern that keeps the vendor's compute costs low.
