Computer use agent tools

GitHub: cua | computer-use | ai-agent

  • open-interpreter 59,220 ⭐ Apr 2025 – open-source (AGPL-3.0). Lets an LLM write/run Python, JS, Shell, or Bash locally; can open a browser tab, edit files, plot data, or call any CLI tool. Works on macOS, Linux, Windows (plus Termux & Colab). Big community, plugin system, optional voice mode, and a desktop GUI in beta.
  • cua 5,072 ⭐ Apr 2025 – open-source (MIT). Spins up near-native macOS or Linux VMs on Apple-Silicon Macs (“Lume”) and exposes a vision+action API so any model can pilot the VM. Gives you GPU-accelerated isolation and reproducible sandboxes; ideal when you don’t want an agent touching your main OS.
  • Operator (OpenAI) – closed-source research preview launched 23 Jan 2025. Runs a GPT-4o-powered “Computer-Using Agent” that sees web pages, clicks, scrolls, fills forms, and hands control back to the user when needed. Hosted in an OpenAI-managed Chromium sandbox, so it works from any OS with a browser. Safety layers require confirmation for payments and log-ins.
  • Claude Computer Use – closed beta inside Claude 3.5 Sonnet (since late 2024). Developers get an API that streams screenshots and accepts mouse/keyboard actions, letting Claude automate GUI workflows inside a VM. Cross-platform; still experimental and slower than humans but first “general” computer-use feature from a foundation-model vendor.
  • Agent-S 2,921 ⭐ Apr 2025 – open-source (Apache-2.0). A “generalist-specialist” framework that chains specialist GUI skills under a planner. Scores SOTA on OSWorld/WebArena, supports macOS, Windows, Linux, Android via the companion gui-agents lib, and integrates memory/evaluation loops for continual learning.
  • open-computer-use 1,073 ⭐ Mar 2025 – open-source (Apache-2.0). Launches a secure Ubuntu desktop in E2B’s cloud sandbox, then orchestrates three LLM roles (grounding, vision, action). Streams the desktop to your browser and lets you pause/override at any time. Plug-in list of >10 models.
  • surf 344 ⭐ Apr 2025 – open-source (Apache-2.0). A polished Next.js front-end that wires OpenAI Operator-style agents to an E2B sandbox. Single command to boot a virtual desktop, chat, and watch the agent work. Good starter template for web-based CUAs.
  • gptme 3,751 ⭐ Apr 2025 – open-source (MIT). A terminal-first personal agent that can run shell commands, edit files, browse the web, and use local or cloud LLMs. Works on Linux, macOS, Windows; great when you want automation in the CLI rather than the GUI.
  • pig-python 148 ⭐ Mar 2025 – open-source SDKs (Apache-2.0) for Pig cloud service. Provides on-demand Windows 11 VMs and an API that exposes high-level GUI primitives (type, click, window focus). Targets RPA-style workloads; still alpha, but unique for Windows-first focus and low-latency streaming.
  • langgraph-cua-py 139 ⭐ Mar 2025 – open-source (MIT). Shows how to build a computer-use agent as a LangGraph state machine, defaulting to Ubuntu VMs from Scrapybara but swappable. Provides nodes for vision, memory, human-in-the-loop, and streaming.
  • openmacro 101 ⭐ Oct 2024 – open-source (MIT). Early-stage multimodal assistant that executes Python snippets locally via SambaNova models. Cross-platform CLI; profile system lets you switch API keys or tool sets. Inspired by OpenInterpreter but lighter weight.
  • computer-agent 437 ⭐ Jan 2025 – open-source (MIT), small but lively community. A PyQt desktop wrapper that lets Claude Computer Use drive your actual machine. Shows practical wiring from Anthropic’s API to local mouse/keyboard events; tested on Linux & Windows.

OCR Quality Comparison

  • If you only need to parse references from text‑native PDFs (or reliably OCR’ed ones), GROBID + a good OCR (e.g. OCRmyPDF/Tesseract or a commercial engine) is still the de facto choice.
  • If you want an end‑to‑end cloud API that gives you back both text and layout (so you can easily isolate the References section), Mistral OCR shows the most promise today—just be prepared to do a light post‑processing pass.
  • If you already use Azure services and need enterprise SLA, Azure Document Intelligence will give you excellent raw OCR; layering on a small custom model or post‑processing pipeline can yield solid reference extraction, but it won’t match GROBID out of the box.

Database Migration

Migration Framework Comparison

  • 🟢 dbmate 6,050 ⭐ Jun 2025: One-file Go CLI; timestamp-named SQL in migrations/, wraps Postgres/MySQL/SQLite/ClickHouse/BigQuery/Spanner; all-or-nothing transactions, dbmate new|up|wait|dump, driven by DATABASE_URL—perfect for polyglot stacks. ([github.com][2])
  • migrate 16,811 ⭐ Apr 2025: Go library + CLI streaming .up/.down.sql from local FS, S3, GCS, HTTP or Git; 30 + DB drivers, force version bumps, drop wipes, embeddable in Go services. ([github.com][3])
  • flyway 8,858 ⭐ Jun 2025: CLI/Java-API “migrations-only” engine; auto-executes V*__ SQL files in order, journals state in a single schema-history table; repeatable scripts, dry-run diffs, Docker/K8s images, Gradle/Maven plugins—pipeline-friendly DB versioning. ([github.com][1])
  • goose 8,516 ⭐ Jun 2025: Simple Go tool running sequential/timestamped SQL or Go-code migrations; supports Pg/My/Sqlite/…, with status up down redo commands and importable helper funcs. ([github.com][4])
  • sql-migrate 3,342 ⭐ Apr 2025: Lightweight Go CLI/lib; paired -- +migrate Up/Down sections inside each SQL file, embeds migrations into binaries, works with SQLite/Postgres/MySQL/Oracle/MSSQL. ([pkg.go.dev][5])
  • DbUp 2,461 ⭐ Apr 2025: .NET library executing embedded SQL resources on app start; keeps a journal table, supports preview mode and transactional/non-transactional runs for SQL Server, Postgres, MySQL. ([dbup.readthedocs.io][6])
  • sqitch 2,997 ⭐ May 2025: Dependency-graph change-manager (Perl CLI); plan file instead of numbering, three scripts per change (deploy/verify/revert), cryptographic hashes; runs on Pg, My, SQLite, Oracle, Snowflake & more. ([sqitch.org][7])
  • reshape 1,770 ⭐ May 2025: Rust binary generating zero-downtime Postgres migrations; diff-based plan creates dual-write views/triggers, reshape plan | migrate | abort workflow for safe rollouts. ([github.com][10])
  • migrate 782 ⭐ Apr 2025: Opinionated Postgres roll-forward flow; edit current.sql, CLI watches and commits numbered migrations, integrates tightly with Git history, NPM install. ([github.com][8])
  • pgmigrate 649 ⭐ Jan 2025: Python CLI for Postgres; transactional + online callbacks, versioned .sql patches, rollback support—battle-tested at Yandex. ([github.com][9])
  • fastmigrate 12 ⭐ Jun 2025: Ultra-minimal Python CLI; simply executes sequential .sql (or shell) scripts to bump schema versions, records state in one table, and offers up | down | current commands—nothing but scripts. ([github.com][1], [answer.ai][2])
