🐸 rainfrog
a database management tui for postgres
[!WARNING] rainfrog is currently in beta; the mysql and sqlite drivers are unstable.
the goal for rainfrog is to provide a lightweight, terminal-based alternative to pgadmin/dbeaver.
features
- efficient navigation via vim-like keybindings and mouse controls
- query editor with keyword highlighting and session history
- quickly copy data, filter tables, and switch between schemas
- shortcuts to view table metadata and properties
- cross-platform (macOS, linux, windows, android via termux)
why "rainfrog"?
supported databases
rainfrog has mainly been tested with postgres, and postgres will be the primary database targeted. mysql and sqlite are also supported, but they are currently unstable; use with caution, and check out the known issues section for things to look out for!
disclaimer
this software is currently under active development; expect breaking changes, and use at your own risk. it is not recommended to use this tool with write access on a production database.
installation
cargo
after installing rust (recommended to do so via rustup):
cargo install rainfrog
arch linux
arch linux users can install from the official repositories using pacman:
pacman -S rainfrog
termux
if you are using termux, you'll need to install rust via their package manager:
pkg install rust
and then make sure to install with termux features (and disable default features):
cargo install rainfrog --features termux --no-default-features
nix
nix-env -iA nixos.rainfrog
install script
there is a simple install script that assists in downloading and unpacking a
binary from the release page to ~/.local/bin/
, which you might want to add to
your PATH
variable if it isn't already there. you'll need to select which
binary is appropriate for your system (if you're not sure, you can find out by
installing rust and running rustc -vV
to see the "host" target), and the
script also needs jq and
fzf installed to run.
curl -LSsf https://raw.githubusercontent.com/achristmascarl/rainfrog/main/install.sh | bash
release page binaries
- manually download and unpack the appropriate binary for your os from the
latest release (if
you're not sure which binary to pick, you can find out by installing rust and
running
rustc -vV
to see the "host" target) - move the binary to a folder in your
PATH
environment variable
usage
Usage: rainfrog [OPTIONS]
Options:
-M, --mouse <MOUSE_MODE> Whether to enable mouse event support. If enabled, the default mouse event handling for your terminal
will not work. [possible values: true, false]
-u, --url <URL> Full connection URL for the database, e.g. postgres://username:password@localhost:5432/dbname
--username <USERNAME> Username for database connection
--password <PASSWORD> Password for database connection
--host <HOST> Host for database connection (ex. localhost)
--port <PORT> Port for database connection (ex. 5432)
--database <DATABASE> Name of database for connection (ex. postgres)
--driver <DRIVER> Driver for database connection (ex. postgres)
-h, --help Print help
-V, --version Print version
with connection options
if any options are not provided, you will be prompted to input them. if you do not provide an input, that option will default to what is in your environment variables.
rainfrog \
--driver <db_driver> \
--username <username> \
--host <hostname> \
--port <db_port> \
--database <db_name>
with connection url
the connection_url
must include all the necessary options for connecting
to the database (ex. postgres://username:password@localhost:5432/postgres
).
it will take precedence over all connection options.
rainfrog --url $(connection_url)
docker run
for postgres and mysql, you can run it by specifying all of the options as environment variables:
docker run --platform linux/amd64 -it --rm --name rainfrog \
--add-host host.docker.internal:host-gateway \
-e db_driver="db_driver" \
-e username="<username>" \
-e password="<password>" \
-e hostname="host.docker.internal" \
-e db_port="<db_port>" \
-e db_name="<db_name>" achristmascarl/rainfrog:latest
if you want to provide a custom combination of options and omit others, you can override the Dockerfile's CMD like so:
docker run --platform linux/amd64 -it --rm --name rainfrog \
achristmascarl/rainfrog:latest \
rainfrog # overrides CMD, additional options would come after
since sqlite is file-based, you may need to mount a path to the sqlite db as a volume in order to access it:
docker run --platform linux/amd64 -it --rm --name rainfrog \
-v ~/code/rainfrog/dev/rainfrog.sqlite3:/rainfrog.sqlite3 \
achristmascarl/rainfrog:latest \
rainfrog --url sqlite:///rainfrog.sqlite3
customization
rainfrog can be customized by placing a rainfrog_config.toml
file in
one of the following locations depending on your os, as determined by
the directories crate:
Platform | Value | Example |
---|---|---|
Linux | $XDG_CONFIG_HOME /_project_path_ or $HOME /.config/_project_path_ |
/home/alice/.config/barapp |
macOS | $HOME /Library/Application Support/_project_path_ |
/Users/Alice/Library/Application Support/com.Foo-Corp.Bar-App |
Windows | {FOLDERID_LocalAppData} \_project_path_ \config |
C:\Users\Alice\AppData\Local\Foo Corp\Bar App\config |
you can change the default config location by exporting an environment variable. to make the change permanent, add it to your .zshrc/.bashrc/.*rc file:
export RAINFROG_CONFIG=~/.config
settings
right now, the only setting available is whether rainfrog captures mouse events by default. capturing mouse events allows you to change focus and scroll using the mouse. however, your terminal will not handle mouse events like it normally does (you won't be able to copy by highlighting, for example).
keybindings
you can customize some of the default keybindings, but not all of them. to see a list of the ones you can customize, see the default config file at .config/rainfrog_config.toml. below are the default keybindings.

known issues and limitations
- geometry types are not currently supported
- in sqlite,
EXPLAIN QUERY PLAN
does not work due to an issue with the sql parser; see https://github.com/achristmascarl/rainfrog/issues/106 - for x11 and wayland, yanking does not copy to the system clipboard, only to the query editor's buffer. see https://github.com/achristmascarl/rainfrog/issues/83
- in addition to the experience being subpar if the terminal window is too
small, if the terminal window is too large, rainfrog will crash due to the
maximum area of ratatui buffers being
u16::MAX
(65,535). more details in https://github.com/achristmascarl/rainfrog/issues/60 - for query results with many columns, the height of the rendered
Table
widget may be limited due to the same limitation mentioned above. Could be fixed by https://github.com/ratatui-org/ratatui/issues/1250 - on mac, for VS Code and terminal (and perhaps other editors), a setting for
"use option as meta key" needs to be turned on for Alt/Opt keybindings to
work. (In VS Code, it's
"terminal.integrated.macOptionIsMeta": true
; in kitty, it'smacos_option_as_alt yes
in the config.) - in visual mode, when selecting an entire line, the behavior is not the same as vim's, as it simply moves starts the selection at the head of the line, so moving up or down in lines will break the selection.
- mouse events are only used for changing focus and scrolling; the editor does not currently support mouse events, and menu items cannot be selected using the mouse
