Chipmunk for MAC
Free, open-source log viewer for Mac: open log files of any size, search them live, chart metrics and collect logs over TCP, UDP, serial or commands.
Chipmunk Overview
Chipmunk is a native desktop application, written in Rust, for viewing and analyzing log files. It has no limit on file size beyond your disk space, and because it avoids unnecessary copying, files of any size open with the same speed. It can also collect logs as they happen, over TCP, UDP or a serial port, or from the output of a command or program that you launch from the app.
At its core it is a search tool. You can create sets of filters, save them, reuse them across sessions and give them different colors, and the results update in real time as new data arrives. Regular expressions can capture metrics and turn them into live charts. Chipmunk also supports formats used in the automotive industry, including DLT and SomeIp, with DLT attachments that you can view or export, and DLT traces inside pcap and pcapng captures. Chipmunk is free and open source under the Apache-2.0 license and comes from ESR Labs, part of Accenture. Version 4.3.0 is the latest signed Mac release: the project says 4.4.0 is not available as a signed macOS package for now because of notarization issues, though it can be built from source. There are separate downloads for Apple Silicon and Intel. The project does not state a minimum macOS version.
Key Features
Chipmunk handles very large logs, both from files and from live sources.
- Any file size: limited only by your disk space.
- Live sources: TCP, UDP, serial port and command output.
- Search filters: save, reuse and color-code sets of filters.
- Real-time results: searches update as new logs arrive.
- Charts: live graphs from metrics captured with regular expressions.
- Automotive formats: DLT and SomeIp support out of the box.
- DLT attachments: view or export embedded images, video, audio and text.
- Network captures: work with DLT inside pcap and pcapng files.
What’s New in Version 4.3.0
Chipmunk 4.3.0 improves text file handling, presets and parsing speed.
- A dedicated parser for UTF-16 text files, detected automatically
- Text in other encodings is converted to valid UTF-8 instead of causing search errors
- Recently used presets are kept across sessions, and presets can be pinned
- Recursive folder search when selecting files or dragging them in
- Text file parsing up to 1.35x faster, measured on a 1.5 GB file
- Fixed data loss on very long lines from process and serial sources

Besides containers it runs full Linux machines from 16 distributions, and a lightweight Kubernetes cluster for local development. OrbStack is made by Orbital Labs.Developer Tools
QuotaBarIf you use OpenAI Codex with a ChatGPT account, the usage limits reset on a 5-hour and a weekly window, and checking how much is left means opening Codex or ChatGPT. QuotaBar puts the remaining percentage in the Mac menu bar and refreshes it every 60 seconds. Click the icon for a detailed panel with every limit window and its reset countdown, or turn on a small floating HUD that stays on top of other windows.Developer Tools
Stargazer BarStargazer Bar is a small native menu bar app for Mac that keeps an eye on GitHub repositories for you. It puts a live star count in the menu bar, so you can see how a project is doing without keeping a browser tab open, and a click opens a dropdown with the details: star and fork trend charts, release download totals and a maintainer radar. Public repositories are measured by their stars. Private repositories, which have no stars, are measured by what needs your attention: a failing build, an unanswered issue or a new pull request.Developer Tools
Notch So GoodNotch So Good turns the notch of your MacBook into a small status display for AI coding agents. While Claude Code or the OpenAI Codex CLI works, a black pill extends the notch: a 3D character called Peek sits on the left, and a ring on the right shows how much of your 5-hour usage window is left. The more a session needs you, the further Peek climbs out. When a task finishes, fails or runs into a usage limit, the notch opens into a card that says what happened and in which project, and a click jumps to the exact terminal tab, tmux pane included.Developer Tools
Claude UsageClaude Usage is a small native app for people who use Claude Code. In the menu bar it shows your current five-hour session, your weekly usage for all models and for Sonnet, and your pay-as-you-go credits, each with a usage bar and its reset time, without opening Claude Code. It also adds a one-line readout under your Claude Code prompt with the model, how full the context window is and the tokens used, so you can compact a session before it runs out of room. Each terminal pane shows its own readout, also across tmux.Developer Tools
TintpadTintpad is a free, open-source launcher for developers who work with command-line coding agents such as Claude Code and Codex. Press Option-Command-Space anywhere and a black drop falls out of your Mac's notch, or hangs below the menu bar on Macs without one, with your repositories inside. Type a few letters, press Return, and your own terminal opens at that repository with the agent already running, in the mode you used there last.Developer Tools
