Tracellm is an observability platform for production AI applications. Monitor prompt execution, token consumption, latency, spans, errors, and model calls across your LLM workflows. Export traces using OpenTelemetry (OTLP) and quickly identify bottlenecks before they impact users
ps, top and lsof tell you what is running. witr tells you why. Point it at a process, PID, port, container or file and it traces the chain that explains it - systemd, supervisor, shell or cron - plus who started it, when, from where, and the warnings worth knowing. Run it bare for an interactive TUI with Processes, Ports, Containers and Locks tabs. Or script it: --short for a one-line chain, --json with real exit codes. One static Go binary for Linux, macOS, Windows and BSD.
CPU, memory, battery, network, disk, GPU, temperature and fans in your menu bar. You pick which ones show, and a click opens the detail behind it. Compact Health folds the whole machine into one item that stays quiet until something's off. MIT, macOS 15+.
Motion Editor is an open-source, AI-native alternative to Adobe After Effects. Unlike closed-source motion tools, it gives creators and developers the freedom to customize, extend, and build on the platform. It combines timeline-based editing, 2D/3D motion design, and integrated AI assistance to create a modern, community-driven motion graphics experience.
Give agents a Linux operating system as a library – no sandboxes, VMs, or SaaS. Built on WebAssembly, the same tech powering Cloudflare Workers and Chrome. Support Claude Code, Codex, OpenCode, Pi, Eve, and Flue.
Greplica gives your engineering team and every coding agent a shared memory of the codebase. It continuously extracts decisions, constraints, gotchas, failed approaches, and file-level context from coding sessions, then retrieves only what matters for the task at hand. Unlike static docs or siloed agent memory, Greplica stays grounded in the repo, keeps knowledge fresh, and works across developers, agents, clones, and forks. It is open source, runs locally, and offers a managed shared mode.
Track Claude Code usage: cost, cache, session replay. Run `npx langwatch claude` once. Every session gets cost with cache reads/writes as separate token classes, every bash and MCP call as a span, theoretical vs billed for your Max plan, and a full terminal replay in the UI. Works for Codex too.
🍙 Memmy Agent is a personal memory hub and local AI agent for all AI Agent and tools like Claude Code, Codex, OpenClaw and Hermes. Gives every AI one shared, full-controlled memory — they all remember the same you. Memmy turns chats, decisions, prefs, progresses, and experiences into long-term memory, brings the right context into matching task, also can take on work directly. Local-first by default. Your memory stay under your control: manage them anytime. Free start with 2M ChatGPT tokens.
You bookmark great threads on X and never see them again. Totem turns your new tab into a distraction-free environment for those bookmarks, the way you'd read on Substack. Open a thread full-width, highlight what matters, search everything, export etc.
Task Monki is an open-source desktop app for managing coding agents from task to pull request. Run several tasks at once, follow each agent’s progress, preview every result without manually setting up services or containers, send work to another agent for review and fixes, and bring multiple agents into the same discussion, where they can respond to each other, compare approaches, and challenge assumptions.
SUB/WAVE turns your music library into a real radio station: one shared stream, an AI DJ that picks tracks, reads idents and takes requests in plain language. Self-hosted, works with local LLMs, MIT licensed. Web, iOS, Android and desktop players.
Connect Claude, OpenAI, Gemini or Grok to Ycode and use your preferred AI directly inside the website builder. Describe what you want to change, and the agent can update designs, manage CMS content, and build or improve components for you
🎬 Open source, transcript-based video editor that lives in the browser. Edit videos by simply editing the transcript text. Runs fully in the browser: Local, free and offline!
Open-source AI CLI that answers security questions across cloud, code and runtime - GitHub, GitLab, AWS, GCP, Azure, K8s. Ask in plain language: "what's publicly exposed that shouldn't be?" or "can my CI escalate to cloud admin?". Read-only by construction: every call is resolved to its IAM actions and authorized against a read-only policy before credentials attach. It can't modify your infra even if asked. Unlike MCP tools, it writes JS in a sandboxed runtime - a script per turn, not one call.
An always-on AI agent that lives on a cheap little Raspberry Pi in your home, with a real phone number you text over iMessage or SMS from anywhere. It runs Hermes, an open-source agent, and installs by handing the guide to a coding agent that works over SSH. Best of all, it's a foundation: build a family calendar on a kitchen screen, a recipe helper on the fridge, whatever you dream up. We build in public — join the Discord to see what others are making.
FindDiskKiller is a native macOS disk activity monitor that reveals which apps and AI coding agents are driving reads and writes. Track per-process disk I/O, CPU and network activity, inspect live file access, trace folders, and view SMART/NVMe drive health. Completely free and open source.
Garry Tan's open-sourced gstack specialists — CEO, CSO, QA Lead, a YC-office-hours partner and 15 more — join your real Google Meet as voice bots with 3D avatars. They open in-persona, take turns, critique your shared screen out loud, and drop notes in chat. Free, MIT, and the brain is your own coding-agent session. Built on AgentCall.
Superfile is a modern terminal file manager with a polished multi-panel interface, strong previews, and deep customization. It lets you browse, preview, and move files across panes the way a desktop file manager would, while staying fully keyboard-driven and fast.
Capsomnia turns Caps Lock into a physical switch that keeps your MacBook awake. Keep Claude Code, Codex, other AI agents, SSH sessions, builds, downloads, and more running after you close the lid. If Caps Lock is already assigned, choose another shortcut. The Caps Lock light still shows whether Capsomnia is active. The app is free and open source, signed and notarized. No accounts or telemetry. We’ve already seen strong interest in Japan: 2.3M+ views and 6,000+ downloads.
a new groupchat platform for teams of people and agents of all sizes, built to reduce our dependency on slack and github. model-agnostic, decentralized, self-sovereign, and open source. 🐝
Vizhi (Tamil for "eye") watches your Codex CLI sessions so you don't have to. Six live sessions on a Logitech MX Creative Keypad, one-press approvals, local Whisper voice prompts. No keypad? A local browser dashboard is available.
