Process Compose is a scheduler and orchestrator for managing non-containerized applications [^2]. DevWebUI lets a developer start, stop and restart local dev servers from one dashboard, and see each one's status, CPU, memory and logs [^3]. On needs, devenv's sources speak of reproducible environments defined once [^1], and Process Compose's sources describe process recovery policies [^2] and restarting a process when its files change [^2]. DevWebUI's claims cover a dashboard for starting and watching local servers [^3], a small file in each repo that lists the servers to run [^3] and a way for AI assistants to control your dev servers through 43 tools [^3]. ## What devenv, Process Compose is built for devenv lets users declare packages, languages, services, tasks, secrets and tooling once so every developer and CI gets the same reproducible environment [^1]. It installs on Linux, macOS and WSL once Nix is installed [^1]. It supports 43 preconfigured services, including PostgreSQL, Redis, MySQL, RabbitMQ, MinIO, Caddy and Elasticsearch [^1]. Process Compose is a scheduler and orchestrator for managing non-containerized applications [^2]. It provides dependency graph visualization in its CLI, TUI and API [^2]. It supports process recovery policies [^2]. It can restart a process when its files change, optionally cascading to its dependents [^2]. ## What DevWebUI is built for DevWebUI is made by the team that publishes this site. It lets you start, stop and restart your local dev servers from one dashboard, and see each one's status, CPU, memory and logs [^3]. One small file per repo lists the servers to run, and processes changed in the GUI are written back to that file [^3]. When a port is already taken, it shows which process holds it and can free the port if you ask [^3]. You can open any server it manages through one DevWebUI address on your own machine, and live page reloading in your browser keeps working through it [^3]. Errors are collected into one log that merges repeats and is kept across restarts, and each file:line link opens in your editor [^3]. A setting in the repo file can start the project's Docker services first, such as a database, wait until they are ready and pass their connection settings to your servers [^3]. You can also set threshold alert rules and see a history of the alerts that fired [^3]. AI assistants can control your dev servers through 43 tools, using the same background service as the dashboard [^3]. ## Pricing and fees devenv is MIT licensed [^1]. The devenv sources here do not state a paid tier or a dollar price, so no price is published here [^1]. The Process Compose sources here do not state a price or a licence, so its price is not published here. DevWebUI is free, and its core features need no account [^3]. It is open source under the MIT License [^3]. No paid tier price is stated in its sources. ## Setting it up and daily use devenv installs on Linux, macOS and WSL once Nix is installed [^1]. It supports 43 preconfigured services, including PostgreSQL, Redis, MySQL, RabbitMQ, MinIO, Caddy and Elasticsearch [^1]. Its sources here say nothing more about its daily use. Process Compose is a single binary with no other dependencies because it is written in Go [^2]. It can be used through a terminal user interface or CLI modes [^2]. Its sources here say nothing more about its daily use. On Windows, DevWebUI is installed by downloading devwebui-windows-x64.exe from GitHub Releases [^3]. On any operating system, you run bun install and then bun run dev [^3]. There is a prebuilt Windows x64 app, other systems run it from source with Bun, and the tray app is Windows-only for now [^3]. On Windows, a tray icon keeps DevWebUI running in the background and has Open, Restart and Quit options [^3]. Daily, you control servers from the dashboard [^3] or from a devwebui command-line tool that lets you control servers without the dashboard [^3]. If the last shutdown was not clean, the next launch loads your projects but starts nothing automatically [^3]. ## Things to check before you choose Ask what you need the tool to manage: a reproducible environment defined once for every developer and CI, or non-containerized applications scheduled and orchestrated. devenv's sources speak of declaring packages, languages, services, tasks, secrets and tooling once for the same reproducible environment [^1], and DevWebUI's claims speak of local dev servers [^3]. Check your operating system. devenv installs on Linux, macOS and WSL once Nix is installed [^1]. DevWebUI has a prebuilt Windows x64 app, and other systems run it from source with Bun [^3]. Check cost and accounts. DevWebUI is free with no account for core features [^3]. Check what data leaves your machine. DevWebUI sends an anonymous install ping with update checks unless you set DEVWEBUI_NO_PING=1 [^3]. Check devenv's and Process Compose's own pages for their data handling, since the facts here do not cover it. Check access control if others can reach the tool. DevWebUI can be set to ask for a key before other programs can control it, and a browser gets that key by typing a 6-digit pairing code, with a few listed exceptions [^3]. ## How to choose If you need a reproducible environment declared once for every developer and CI, devenv's sources say that is its purpose [^1]. If you want to schedule and orchestrate non-containerized applications, Process Compose's page says that is what it does [^2]. If you want process recovery policies, Process Compose's page describes that [^2]. If you want to start, stop and restart local dev servers from one dashboard with status, CPU, memory and logs, DevWebUI's claims describe that [^3]. If you want a small file in your repo that lists the servers to run [^3], with Docker services started first [^3], DevWebUI's claims describe that. If you want an AI assistant to work with the tool, Process Compose has an MCP server integration for AI assistants [^2], and DevWebUI lets AI assistants control your dev servers through 43 tools [^3]. If you want a free tool with no account for core features, DevWebUI's claims say that [^3]. ## Frequently asked questions ### Is devenv free to use? devenv is MIT licensed [^1].
