Developer Tools And Environments

Local development stack managers, benchmarks and debugging consoles share this page with monitoring platforms, cloud emulators and container build tools. Local stack managers are described by the runtimes and databases they bundle, plus SSL and mail handling. Benchmark and static analysis entries state what they cover, such as Django REST Framework serialization or React re-renders. Each entry carries the project link and the support, licensing and pricing notes that affect adoption.

  • https://github.com/crizant/probe — Fast, native, local-first API client (Postman/Insomnia alternative) for macOS, Windows, and Linux; built in Rust with GPUI (GPU-rendered, no Electron/WebView). Ships two interfaces over the same core: an agent/CI-friendly CLI (human-readable output plus deterministic versioned JSON) and a desktop app. Uses OpenCollection YAML as workspace format, stores collections on the filesystem (Git-friendly), and needs no account or cloud service. Releases are unsigned, so macOS Gatekeeper / Windows SmartScreen warn on first launch.
  • https://github.com/marixdev/lstack — Local PHP development stack manager for Windows/Linux (Electron); virtual hosts, SSL, databases, and project templates.
  • https://www.servbay.com/ — ServBay: AI-native local development environment for macOS 12+ and Windows 10+ (XAMPP/MAMP/Laragon/Laravel Herd alternative). Runs multiple versions side by side of PHP, Node.js, Python, Go, Java, .NET, Ruby, and Rust, plus MySQL, MariaDB, PostgreSQL, MongoDB, Redis, Memcached, and SQLite. Built-in SSL, local DNS/custom domains, an SMTP/POP3 mail server, Ollama local models, an AI gateway for multiple providers (keys stored encrypted locally), and an MCP server so agents like Claude Code, Cursor, or Codex can manage services, sites, and databases. Free tier covers 5 sites / 5 DNS records; Pro costs 9.90/moor9.90/mo or 59/yr (unlimited sites, mail server, PKI, backups); Team costs 39.90/moor39.90/mo or 399/yr (10 seats).
  • https://envkit.net/ — EnvKit: free desktop app for Windows 10/11 and macOS (Apple Silicon) that bundles a local PHP/Node dev stack into one control panel (Laragon/Herd-style). Choose nginx or Apache, run multiple PHP versions with per-site isolation and on-demand Xdebug, and use MySQL/MariaDB, PostgreSQL, Redis, MongoDB, and Mailpit. It creates a local CA for trusted HTTPS on *.test domains, and services start automatically when a site is accessed. Also supports Laravel Reverb, cron jobs, dump interception, N+1 query detection, admin UIs (phpMyAdmin, pgweb, mongo-express), bulk import from Laragon, and MCP control from an AI assistant. No account needed; binaries ship via Env-Kit/envkit-releases, and it is not clearly open source.

  • https://github.com/ctrlplanedev/ctrlplane — Open-source release governance control plane that sits above existing CI/CD, GitOps, and IaC tooling; enforces promotion sequencing, policy gates, and rollout visibility for multi-cloud, multi-region, multi-service deployments.
  • https://github.com/liriliri/chii — Remote debugging tool like weinre, but using the latest Chrome DevTools frontend to inspect and debug pages on remote/mobile devices.
  • https://github.com/liriliri/eruda — Console for mobile browsers; an on-page DevTools panel for inspecting elements, console, network, resources, and more on mobile web.
  • https://github.com/podman-container-tools/buildah — Tool that facilitates building OCI container images; daemonless, scriptable image builds without requiring a running Docker daemon.
  • https://github.com/ThisIs-Developer/Markdown-Viewer — Fast, GitHub-style Markdown editor and previewer with live preview, Mermaid diagrams, LaTeX math, syntax highlighting, PDF export, and multi-tab support; runs in-browser, via Docker, or as a desktop app.
  • https://github.com/orailnoor/DroidDesk — Turns an Android phone into a real Linux desktop using Termux, Termux X11, TUR, and Proot; runs VS Code, Firefox, LibreOffice, Blender, and more over X11 or VNC.
  • https://github.com/heyputer/puter — Advanced, open-source, self-hostable "internet computer": a web-based desktop environment with built-in apps (notepad, spreadsheet, camera), cloud storage, an app marketplace, and AI integration, accessible from any device.
  • https://github.com/caobahuong/kafka-connect-dynamic-filter — Kafka Connect SMT for filtering Debezium CDC records with dynamic JSON rules sourced from Redis, a Kafka topic, or a file; rules update on the next record with no connector restart or downtime.
  • https://horizon.nckrtl.com/ — Horizon New Dawn: modernized UI replacement for Laravel Horizon queue monitoring; adds advanced filtering, instance/supervisor controls, batch management, and failure recovery via a single composer package with no config changes.
  • https://github.com/welldone-software/why-did-you-render — Monkey-patches React to notify you about potentially avoidable re-renders, helping track down unnecessary component updates; also works with React Native.
