As (yet another) process/system visualization and management application, bottom supports the typical features:
Graphical visualization widgets for:
- CPU usage over time, at an average and per-core level
- RAM and swap usage over time
- Network I/O usage over time
with support for zooming in/out the current time interval displayed.
Widgets for displaying info about:
A process widget for displaying, sorting, and searching info about processes, as well as support for:
Cross-platform support for Linux, macOS, and Windows, with more planned in the future.
Customizable behaviour that can be controlled with command-line flags or a config file, such as:
- Custom and built-in colour themes
- Customizing widget behaviour
- Changing the layout of widgets
- Filtering out entries in some widgets
Some other nice stuff, like:
You can find more details in the documentation.
bottom officially supports the following operating systems and corresponding architectures:
- macOS (
- Linux (
- Windows (
These platforms are tested to work for the most part and issues on these platforms will be fixed if possible. Furthermore, binaries are expected to be built and tested using the most recent version of stable Rust at the time.
For more details on supported platforms and known problems, check out the documentation.
bottom may work on a number of platforms that aren't officially supported. Note that unsupported platforms:
- Might not be tested in CI to build or pass tests (see here for checked platforms).
- Might not be properly tested by maintainers prior to a stable release.
- May only receive limited support, such as missing features or bugs that may not be fixed.
Note that some unsupported platforms may eventually be officially supported (e.g., FreeBSD).
A non-comprehensive list of some currently unofficially supported platforms that may compile/work include:
- FreeBSD (
- Linux (
- Android (

There are a few ways to go about doing this manually. Note that you probably want to do so using the most recent version of stable Rust, which is how the binaries are built:
# If required, update Rust on the stable channel first rustup update stable # Option 1 - Download from releases and install curl -LO https://github.com/ClementTsang/bottom/archive/0.9.6.tar.gz tar -xzvf 0.9.6.tar.gz cargo install --path . --locked # Option 2 - Clone the repo and install manually git clone https://github.com/ClementTsang/bottom cd bottom cargo install --path . --locked # Option 3 - Clone and install directly from the repo all via Cargo cargo install --git https://github.com/ClementTsang/bottom --locked # You can also pass in the target-cpu=native flag for # better CPU-specific optimizations. For example: RUSTFLAGS="-C target-cpu=native" cargo install --path . --locked
You can also use the pre-built release binaries manually:
- Latest stable release, generated off of the release branch
- Latest nightly release, generated off of the
mainbranch at 00:00 UTC daily
To use, download and extract the binary that matches your system. You can then run by doing:
or by installing to your system following whatever the procedure is for installing a binary to your system.
The release binaries are packaged with shell auto-completion files for bash, fish, zsh, and Powershell. To install them:
- For bash, move

Thanks to all contributors:
This application was written with many, many libraries, and built on the work of many talented people. This application would be impossible without their work. I used to thank them all individually but the list got too large...
And of course, another round of thanks to all the contributors and package maintainers!
