CodeBurn is a free, open-source, local-first tool by AgentSeal that reads session files written by AI coding tools and reports token usage and estimated cost by provider, model, project, task, and activity. It provides a terminal dashboard and reports, a localhost web dashboard, desktop and tray or menubar views, exports, model comparisons, subscription-plan tracking, and optional cross-device aggregation. Its deterministic analyzers classify work into task categories from tool usage and message keywords, calculate token costs using LiteLLM pricing cached locally, and scan coding-agent sessions for patterns such as repeated file reads, low read-to-edit ratios, uncapped shell output, unused MCP servers, bloated configuration, and retry-heavy work. The optimize command produces estimated savings and fixes; applicable configuration changes are backed up and journaled so they can be undone and later compared with observed usage. The yield command heuristically correlates sessions with Git commits to classify spend as productive, reverted, abandoned, or ambiguous. The guard feature installs opt-in Claude Code hooks for soft and hard session-spending caps, checkpoints, and status-line reporting. CodeBurn also exposes local usage and savings through an MCP server over stdio. The CLI reads data from the local machine without wrappers, proxies, API keys, or uploads; the optional desktop applications can send anonymous bucketed telemetry after consent. It requires Node.js 22.13 or newer, and the repository is licensed under MIT.

useAgent is an open-source AI coworker that gives Claude Code, Codex, OpenCode, and Pi a shared workspace with isolated Linux computers, repositories, terminals, browsers, and team tools. It can handle research, websites, spreadsheets, reports, presentations, and code changes, returning usable files, artifacts, or pull requests through a web app, Slack, REST API, or scheduled tasks. Each run is stored as an event log in Postgres and uses a common event contract across supported agent engines. Daytona or CubeSandbox provides the isolated workstation, while integrations cross a trusted gateway as typed tools so credentials remain on the control plane rather than entering the sandbox. The workspace also supports versioned skills and playbooks, team knowledge and memory, approval-gated tools, revisioned workpieces, and durable sessions. The repository describes useAgent as alpha software with changing APIs and schemas. It can be self-hosted on Linux using Bun and Postgres with pgvector, and is licensed under AGPL-3.0-only; a commercial license is available for proprietary embedding, distribution, OEM, or white-label use.

Free Claude Code is an independent open-source local proxy for routing Claude Code, Codex, Pi, OpenCode, and other coding-agent requests to selected free, paid, subscription, or local model providers while preserving their existing APIs. It provides a searchable model catalog and an Admin UI for configuring providers, supports automatic fallback to another configured model after provider retries are exhausted, and can be launched from a terminal, desktop app, IDE, Discord, Telegram, or phone. Optional RTK filtering reduces common terminal-output tokens, while voice input can use local Whisper or NVIDIA NIM transcription. The project states that it is not affiliated with or endorsed by Anthropic, and that provider free-tier availability and limits may change.

Multi-Agent Workbench is a local-first browser control room for orchestrating coding agents such as Claude Code, Codex CLI, and generic PTY-based command-line agents. Agents work in task rooms under editable YAML role cards that define permissions, speaking style, and decision boundaries; a rule-driven orchestrator pauses execution and risky commands for human approval, while persistent sessions expose terminal activity and status. The system uses a local event-driven architecture with a React interface, Fastify backend, REST API, server-sent events, agent adapters, an approval service, and a SQLite event store. Every action passes through the API and is recorded in an append-only event log, whose events are projected into timelines, decisions, terminal views, artifacts, and diff views. It also provides task templates, Markdown reports and decision logs, real-time room updates, and configurable risk resolutions. Code-writing agents are intended to use isolated Git worktrees, with diff and patch review before changes reach the main workspace; the repository marks this worktree and merge flow as in progress.
