SayDeploy is published by LunarWerx, which makes some of the tools compared here.

Concurrently is a Node.js tool that can run any commands [1]. PM2 is a daemon process manager designed to keep an application online around the clock [2]. DevWebUI starts, stops and restarts local dev servers from one dashboard [3]. PM2 offers a web based monitoring dashboard started with pm2 monitor [2], and DevWebUI shows status, CPU, memory and logs for each server [3]. PM2 has an AI assistant that connects Claude, Cursor or any MCP-compatible assistant to monitoring data after signing in with a PM2.io account [2]. DevWebUI lets AI assistants control your dev servers through 43 tools [3]. DevWebUI is free [3], while PM2 Plus has no free plan [4].

The short answer

Concurrently is a Node.js tool that can run any commands [1]. PM2 is a daemon process manager designed to keep an application online around the clock [2]. DevWebUI gives a developer a dashboard to start, stop and restart local dev servers, and shows each one's status, CPU, memory and logs [3].

Depending on needs, Concurrently's page says it can be installed in the global scope or locally for a specific package [1]. PM2's sources describe keeping an app online [2] and web based monitoring [2], and an AI assistant that reads monitoring data such as server status, metrics, logs, exceptions, traces and alerts [2]. DevWebUI's sources cover a dashboard for starting and watching local servers [3], a small file per repo listing the servers to run [3] and a way for AI assistants to control your dev servers through 43 tools [3].

What Concurrently and PM2 are built for

Concurrently's own page says it is written in Node.js but can run any commands [1]. Installation can be in the global scope or locally for a specific package [1]. The tool also prefixes command output so it is easy to follow [1].

PM2's own page calls it a daemon process manager that will help you manage and keep your application online 24/7 [2]. It can be installed globally with npm [2]. The monitoring dashboard is web based and starts with the command pm2 monitor [2].

The PM2 AI Assistant links Claude, Cursor or any MCP-compatible AI assistant to monitoring data such as server status, metrics, logs, exceptions, traces and alerts, secured by OAuth with a PM2.io account [2]. The page says 44 AI tools are available [2] and that it works with Claude Code, Claude Desktop and Cursor [2].

What DevWebUI is built for

DevWebUI is made by the team that publishes this site.

It gives a developer a dashboard to start, stop and restart local dev servers, and shows 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

PM2 Plus does not offer any free plan, but PM2 Runtime remains free as it is open source [4]. Its page mentions a 20% discount on a subscription and says that discount only refers to PM2 Plus [4]. After cancelling a subscription, you finish the current month and then access is disabled [4]. The PM2 sources given here do not state a dollar price for PM2 Plus, so it is not published here [4].

Concurrently's sources here do not state a price, so its price is not published. Check its own pages for any fee.

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

PM2 is installed globally with npm using npm install pm2 -g [2]. For day to day monitoring, the web based dashboard starts with the command pm2 monitor [2]. The AI assistant needs a PM2.io account for the OAuth sign in [2]. The sources here say nothing more about its setup or routine use.

Concurrently can be installed in the global scope or locally for a specific package [1]. Its sources here say nothing more about 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].

Day to day, 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 the tool needs to manage: several commands run at once, local dev servers, or an application kept online around the clock. Concurrently's page speaks of running any commands [1], PM2's page speaks of keeping an application online 24/7 [2], and DevWebUI's claims speak of local dev servers [3].

Check your operating system. Concurrently's sources here do not detail platform support beyond what its page says. DevWebUI has a prebuilt Windows x64 app, and other systems run it from source with Bun [3].

Check cost and accounts. PM2 Plus has no free plan [4], and the PM2 AI Assistant uses a PM2.io account [2]. Concurrently's sources here state no price, so check its own pages.

Check what data leaves your machine. DevWebUI sends an anonymous install ping with update checks unless you set DEVWEBUI_NO_PING=1 [3]. Check PM2's and Concurrently's own pages for 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 run several commands at once and want their output marked apart, Concurrently's page describes output prefixes that make it easy to follow [1].

If you need an application kept online 24/7, PM2's page says that is its purpose [2].

If you want web based monitoring started from a command, PM2's page describes pm2 monitor [2].

If you want a dashboard to start, stop and restart local dev servers 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, PM2's assistant links Claude, Cursor or any MCP-compatible assistant to monitoring data after a PM2.io sign in [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].
