Configuration
mise.toml
mise.toml
is the config file for mise. They can be at any of the following file paths (in order of precedence, top overrides configuration of lower paths):
mise.local.toml
- used for local config, this should not be committed to source controlmise.toml
mise/config.toml
.config/mise.toml
- use this in order to group config files into a common directory.config/mise/config.toml
.config/mise/conf.d/*.toml
- all files in this directory will be loaded in alphabetical order
TIP
Run mise cfg
to figure out what order mise is loading files on your particular setup. This is often a lot easier than figuring out mise's rules.
Notes:
- Paths which start with
mise
can be dotfiles, e.g.:mise.toml
or.mise/config.toml
. - This list doesn't include Configuration Environments which allow for environment-specific config files like
mise.development.toml
—set withMISE_ENV=development
. - See
LOCAL_CONFIG_FILENAMES
insrc/config/mod.rs
for the actual code for these paths and their precedence. Some legacy paths are not listed here for brevity.
These files recurse upwards, so if you have a ~/src/work/myproj/mise.toml
file, what is defined there will override anything set in ~/src/work/mise.toml
or ~/.config/mise.toml
. The config contents are merged together.
TIP
Run mise config
to see what files mise has loaded in order of precedence.
Here is what a mise.toml
looks like:
[env]
# supports arbitrary env vars so mise can be used like direnv/dotenv
NODE_ENV = 'production'
[tools]
# specify single or multiple versions
terraform = '1.0.0'
erlang = ['23.3', '24.0']
# supports everything you can do with .tool-versions currently
node = ['16', 'prefix:20', 'ref:master', 'path:~/.nodes/14']
[alias.node.versions] # project-local aliases
# use vfox:version-fox/vfox-nodejs when running `mise i node@backend`
backend = "vfox:version-fox/vfox-nodejs"
# install node-20.x when running `mise i node@my_custom_node`
my_custom_node = '20'
[tasks.build]
run = 'echo "running build tasks"'
[plugins]
# DEPRECATED: use `alias.<PLUGIN>` instead
# specify a custom repo url
# note this will only be used if the plugin does not already exist
python = 'https://github.com/asdf-community/asdf-python'
mise.toml
files are hierarchical. The configuration in a file in the current directory will override conflicting configuration in parent directories. For example, if ~/src/myproj/mise.toml
defines the following:
[tools]
node = '20'
python = '3.10'
And ~/src/myproj/backend/mise.toml
defines:
[tools]
node = '18'
ruby = '3.1'
Then when inside of ~/src/myproj/backend
, node
will be 18
, python
will be 3.10
, and ruby
will be 3.1
. You can check the active versions with mise ls --current
.
You can also have environment specific config files like .mise.production.toml
, see Configuration Environments for more details.
[tools]
- Dev tools
See Tools.
[env]
- Arbitrary Environment Variables
See environments.
[tasks.*]
- Run files or shell scripts
See Tasks.
[settings]
- Mise Settings
See Settings for the full list of settings.
[plugins]
- Specify Custom Plugin Repository URLs
Use [plugins]
to add/modify plugin shortnames. Note that this will only modify new plugin installations. Existing plugins can use any URL.
[plugins]
elixir = "https://github.com/my-org/mise-elixir.git"
node = "https://github.com/my-org/mise-node.git#DEADBEEF" # supports specific gitref
If you simply want to install a plugin from a specific URL once, it's better to use mise plugin install plugin <GIT_URL>
. Add this section to mise.toml
if you want to share the plugin location/revision with other developers in your project.
This is similar to MISE_SHORTHANDS
but doesn't require a separate file.
[aliases]
- Tool version aliases
The following makes mise install node@my_custom_node
install node-20.x this can also be specified in a plugin. note adding an alias will also add a symlink, in this case:
~/.local/share/mise/installs/node/20 -> ./20.x.x
my_custom_node = '20'
Minimum mise version
Specify the minimum supported version of mise required for the configuration file. If the configuration file specifies a version of mise that is higher than the currently installed version, mise will error out.
min_version = '2024.11.1'
mise.toml
schema
- You can find the JSON schema for
mise.toml
here or at https://mise.jdx.dev/schema/mise.json. - Some editors can load it automatically to provide autocompletion and validation for when editing a
mise.toml
file (VSCode, IntelliJ, neovim, etc.). It is also available in the JSON schema store. - Note that for
included tasks
(see task configuration, there is another schema: https://mise.jdx.dev/schema/mise-task.json)
Global config: ~/.config/mise/config.toml
mise can be configured in ~/.config/mise/config.toml
. It's like local mise.toml
files except that it is used for all directories.
[tools]
# global tool versions go here
# you can set these with `mise use -g`
node = 'lts'

[_]
foo = "bar"
System config: /etc/mise/config.toml
Similar to ~/.config/mise/config.toml
but for all users on the system. This is useful for setting defaults for all users.
.tool-versions
The .tool-versions
file is asdf's config file and it can be used in mise just like mise.toml
. It isn't as flexible so it's recommended to use mise.toml
instead. It can be useful if you already have a lot of .tool-versions
files or work on a team that uses asdf.
Here is an example with all the supported syntax:
node 20.0.0 # comments are allowed
ruby 3 # can be fuzzy version
shellcheck latest # also supports "latest"
jq 1.6
erlang ref:master # compile from vcs ref
go prefix:1.19 # uses the latest 1.19.x version—needed in case "1.19" is an exact match
shfmt path:./shfmt # use a custom runtime
node lts # use lts version of node (not supported by all plugins)
node sub-2:lts # install 2 versions behind the latest lts (e.g.: 18 if lts is 20)
python sub-0.1:latest # install python-3.10 if the latest is 3.11
See the asdf docs for more info on this file format.
Scopes
Both mise.toml
and .tool-versions
support "scopes" which modify the behavior of the version:
ref:<SHA>
- compile from a vcs (usually git) refprefix:<PREFIX>
- use the latest version that matches the prefix. Useful for Go since1.20
would only match1.20
exactly butprefix:1.20
will match1.20.1
and1.20.2
etc.path:<PATH>
- use a custom compiled version at the given path. One use-case is to re-use Homebrew tools (e.g.:path:/opt/homebrew/opt/node@20
).sub-<PARTIAL_VERSION>:<ORIG_VERSION>
- subtracts PARTIAL_VERSION from ORIG_VERSION. This can be used to express something like "2 versions behind lts" such assub-2:lts
. Or 1 minor version behind the latest version:sub-0.1:latest
.
Idiomatic version files
mise supports "idiomatic version files" just like asdf. They're language-specific files like .node-version
and .python-version
. These are ideal for setting the runtime version of a project without forcing other developers to use a specific tool like mise/asdf.
They support aliases, which means you can have an .nvmrc
file with lts/hydrogen
and it will work in mise and nvm. Here are some of the supported idiomatic version files:
Plugin | Idiomatic Files |
---|---|
crystal | .crystal-version |
elixir | .exenv-version |
go | .go-version , go.mod |
java | .java-version , .sdkmanrc |
node | .nvmrc , .node-version |
python | .python-version , .python-versions |
ruby | .ruby-version , Gemfile |
terraform | .terraform-version , .packer-version , main.tf |
yarn | .yarnrc |
In mise these are enabled by default. You can disable them with mise settings idiomatic_version_file=false
. There is a performance cost to having these when they're parsed as it's performed by the plugin in bin/parse-version-file
. However, these are cached so it's not a huge deal. You may not even notice.
INFO
asdf called these "legacy version files". I think this was a bad name since it implies that they shouldn't be used—which is definitely not the case IMO. I prefer the term "idiomatic" version files since they are version files not specific to asdf/mise and can be used by other tools. (.nvmrc
being a notable exception, which is tied to a specific tool.)
Settings

Environment variables
TIP
Normally environment variables in mise are used to set settings so most environment variables are in that doc. The following are environment variables that are not settings.
A setting in mise is generally something that can be configured either as an environment variable or set in a config file.
mise can also be configured via environment variables. The following options are available:
MISE_DATA_DIR
Default: ~/.local/share/mise
or $XDG_DATA_HOME/mise
This is the directory where mise stores plugins and tool installs. These are not supposed to be shared across machines.
MISE_CACHE_DIR
Default (Linux): ~/.cache/mise
or $XDG_CACHE_HOME/mise
Default (macOS): ~/Library/Caches/mise
or $XDG_CACHE_HOME/mise
This is the directory where mise stores internal cache. This is not supposed to be shared across machines. It may be deleted at any time mise is not running.
MISE_TMP_DIR
Default: std::env::temp_dir()
implementation in rust
This is used for temporary storage such as when installing tools.
MISE_SYSTEM_DIR
Default: /etc/mise
This is the directory where mise stores system-wide configuration.
MISE_GLOBAL_CONFIG_FILE
Default: $MISE_CONFIG_DIR/config.toml
(Usually ~/.config/mise/config.toml)
This is the path to the config file.
MISE_GLOBAL_CONFIG_ROOT
Default: $HOME
This is the path which is used as for the global config file.
MISE_ENV_FILE
Set to a filename to read from env from a dotenv file. e.g.: MISE_ENV_FILE=.env
. Uses dotenvy under the hood.
MISE_${PLUGIN}_VERSION
Set the version for a runtime. For example, MISE_NODE_VERSION=20
will use [email protected] regardless of what is set in mise.toml
/.tool-versions
.
MISE_TRUSTED_CONFIG_PATHS
This is a list of paths that mise will automatically mark as trusted. They can be separated with :
.
MISE_LOG_LEVEL=trace|debug|info|warn|error
These change the verbosity of mise.
You can also use MISE_DEBUG=1
, MISE_TRACE=1
, and MISE_QUIET=1
as well as --log-level=trace|debug|info|warn|error
.
MISE_LOG_FILE=~/mise.log
Output logs to a file.
MISE_LOG_FILE_LEVEL=trace|debug|info|warn|error
Same as MISE_LOG_LEVEL
but for the log file output level. This is useful if you want to store the logs but not have them litter your display.
MISE_QUIET=1
Equivalent to MISE_LOG_LEVEL=warn
.
MISE_HTTP_TIMEOUT
Set the timeout for http requests in seconds. The default is 30
.
MISE_RAW=1
Set to "1" to directly pipe plugin scripts to stdin/stdout/stderr. By default stdin is disabled because when installing a bunch of plugins in parallel you won't see the prompt. Use this if a plugin accepts input or otherwise does not seem to be installing correctly.
Sets MISE_JOBS=1
because only 1 plugin script can be executed at a time.
MISE_FISH_AUTO_ACTIVATE=1
Configures the vendor_conf.d script for fish shell to automatically activate. This file is automatically used in homebrew and potentially other installs to automatically activate mise without configuring.
Defaults to enabled, set to "0" to disable.
