Overmind is a process manager for Procfile-based applications and tmux [^1]. DevWebUI starts, stops and restarts local dev servers from one dashboard [^2]. DevWebUI says it is free, and its core features need no account. [^2] Overmind's sources here state no price. | Option | Own fee | Needs first | Platforms | Install | |---|---|---|---|---| | Overmind | Not published | tmux must be installed first [^1] | Linux, *BSD and macOS only [^1] | Build from source needs Go 1.21 or later [^1] | | DevWebUI | Free, core features need no account [^2] | Bun to run from source [^2] | Prebuilt Windows x64 app; other systems from source [^2] | devwebui-windows-x64.exe from GitHub Releases, or bun install then bun run dev [^2] | ## The short answer Overmind is a process manager for Procfile-based applications and tmux [^1]. DevWebUI lets a developer start, stop and restart local dev servers from one dashboard, and see each one's status, CPU, memory and logs [^2]. On needs, Overmind's page says it starts processes in a tmux session so you can connect to any process and control it [^1]. It can also restart a single process on the fly [^1]. DevWebUI's sources cover a dashboard for starting and watching local servers [^2], a small file in each repo that lists the servers to run [^2] and a way for AI assistants to control your dev servers through 43 tools [^2]. ## What Overmind is built for Overmind's own page calls it a process manager for Procfile-based applications and tmux [^1]. It starts processes in a tmux session, so you can connect to any process and gain control over it [^1]. It can restart a single process on the fly [^1]. It can let a specified process die without interrupting all the other ones [^1]. It can also restart specified processes automatically when they die [^1]. It uses tmux's control mode to capture process output [^1]. It can read environment variables from a file and use them as parameters [^1]. By default it assigns a port base of 5000 and a port step of 100 to processes [^1]. It starts one instance of each process by default [^1]. ## 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 [^2]. One small file per repo lists the servers to run, and processes changed in the GUI are written back to that file [^2]. When a port is already taken, it shows which process holds it and can free the port if you ask [^2]. 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 [^2]. Errors are collected into one log that merges repeats and is kept across restarts, and each file:line link opens in your editor [^2]. A setting in the repo file can start the project's Docker services first, wait until they are ready and pass their connection settings to your servers [^2]. You can also set threshold alert rules and see a history of the alerts that fired [^2]. AI assistants can control your dev servers through 43 tools, using the same background service as the dashboard [^2]. ## Pricing and fees The Overmind sources given here state no price, so its price is not published here. DevWebUI is free, and its core features need no account [^2]. It is open source under the MIT License [^2]. No paid tier price is stated in its sources. One cost note for Overmind: it requires tmux to be installed first [^1]. Building it from source requires Go 1.21 or later [^1]. ## Setting it up and daily use Overmind works with tmux, so you need to install tmux first [^1]. Building from source requires Go 1.21 or later [^1]. It supports Linux, *BSD and macOS only at the moment [^1]. Day to day, you connect to any process in its tmux session [^1] and can restart one process without the rest [^1]. The sources here say nothing more about its setup. On Windows, DevWebUI is installed by downloading devwebui-windows-x64.exe from GitHub Releases [^2]. On any operating system, you run bun install and then bun run dev [^2]. There is a prebuilt Windows x64 app, other systems run it from source with Bun, and the tray app is Windows-only for now [^2]. On Windows, a tray icon runs the background service and has Open, Restart and Quit options [^2]. Daily, you control servers from the dashboard [^2] or from a devwebui command-line tool [^2]. If the last shutdown was not clean, the next launch loads your projects but starts nothing automatically [^2]. ## Things to check before you choose Check your operating system. Overmind supports Linux, *BSD and macOS only at the moment [^1]. DevWebUI has a prebuilt Windows x64 app, and other systems run it from source with Bun [^2]. Check what must be installed first. Overmind needs tmux [^1]. Check how your project lists its servers: a Procfile [^1] or a small repo file [^2]. Check what data leaves your machine. DevWebUI sends an anonymous install ping with update checks unless you set DEVWEBUI_NO_PING=1 [^2]. Check Overmind's own pages for its data handling. Check access control if others can reach the tool. DevWebUI can require a credential on its API, and browsers get a key by typing a 6-digit pairing code [^2]. ## How to choose If you work from a Procfile and want to connect to processes in tmux, Overmind's page describes that [^1] [^1]. If you want automatic restarts of specified processes when they die, Overmind's page says it can do that [^1]. 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 [^2]. If you want Docker services started first [^2] or AI assistants controlling servers through 43 tools, DevWebUI's claims describe that [^2]. If you want a free tool with no account for core features, DevWebUI's claims say that [^2]. ## Frequently asked questions ### Is Overmind free to use? The Overmind sources given here state no price and no plans, so its price is not published here. Check its own pages for licence and cost.
