+# Run Dev Processes With Overmind Instead Of Foreman
+
+Most Rails projects that I have worked on have used
+[`foreman`](https://github.com/ddollar/foreman) as a development dependency for
+running all the processes declared in your Procfile (`Procfile.dev`). As far as
+having a single command to run everything (Rails server, asset building,
+worker(s), etc.), it does the job.
+
+`foreman` has some serious points of friction though. The one that really stands
+out to me is that when I try to debug the development Rails server with
+`binding.irb` or `binding.pry`, the other processes tend to interfere.
+
+The alternative to `foreman` that I've been trying out recently is
+[`overmind`](https://github.com/DarthSim/overmind). A specific selling point of
+`overmind` is that it runs all the development processes in a `tmux` session.
+That means you can individually connect to, inspect, and restart each process.
+
+Once you've installed `overmind` (`brew install overmind`), then you can easily
+swap it in for `foreman` like so:
+
+```bash
+$ overmind start -f Procfile.dev
+```
+
+You can connect to any of those processes directly:
+
+```bash
+$ overmind connect sidekiq
+```
+
+When you want to `binding.irb` the Rails server, you can specifically connect to
+the `web` process to do that.
+
+```bash
+$ overmind connect web
+```
+
+If you need to stop all the process, you can run the `kill` subcommand.
+
+```bash
+$ overmind kill
+```
+
+Lastly, if you have a `bin/dev` script in your project, it is probably using
+`foreman`. If you and your team prefer `overmind`, then update that script
+accordingly and you can simply run `bin/dev` going forward.
