Convos can be configured with either a config file or environment variables.

Any of the settings below can be specified either in a configuration file or as environment variables. Here is an example on how to specify environment variables:

You might want to check out the FAQ for example configurations as well.

$ CONVOS_INVITE_CODE=s3cret ./script/convos daemon

One way of setting a bunch of environment variables is by putting them all in a shell script:

export CONVOS_CONTACT=[email protected]
export CONVOS_HOME=/var/convos
export CONVOS_INVITE_CODE=s3cret
export MOJO_LOG_LEVEL=debug

exec /home/www/convos-stable/script/convos \
  daemon --listen http://*:8000            \
  1>>/home/www/log/convos.log              \

Instead of using environment variables, you can specify configuration settings in a JSON config file. Note that all the settings below are optional, just like the environment variables.

$ /home/www/convos-stable/script/convos /path/to/convos.conf.json \
    --listen http://*:8000

$ cat /path/to/convos.conf.json
  "backend":           "Convos::Core::Backend::File",
  "contact":           "mailto:[email protected]",
  "default_server":    "localhost:6667",
  "log_file":          "/var/log/convos.log",
  "forced_irc_server": "localhost:6667",
  "invite_code":       "s3cret",
  "organization_name": "Awesome hackers",
  "plugins":           {},
  "secure_cookies":    0,
  "secrets":           ["signed-cookie-secret"]

Note: A config file can also be a plain Perl hash. If you want to use the perl format instead of JSON, then just drop the “.json” suffix on the file.


You can make convos listen to a variety of addresses:

# Listen on all IPv4 interfaces
$ ./script/convos daemon --listen http://*:8080

# Listen on all IPv4 and IPv6 interfaces
$ ./script/convos daemon --listen "http://[::]:8000"

# Listen on a specific IPv4 and IPv6 interface
$ ./script/convos daemon \
  --listen "" \
  --listen "http://[::1]:8080"

# Listen on HTTPS with a default untrusted certificate
$ ./script/convos daemon --listen https://*:4000

# Use a custom certificate and key
$ ./script/convos daemon --listen \

# Make convos available behind a reverse proxy
$ MOJO_REVERSE_PROXY=1 ./script/convos daemon \

See MOJO_REVERSE_PROXY for more details about setting up Convos behind a reverse proxy.

Configuration parameters


Can be set to any class name that inherit from Convos::Core::Backend.

Default: Convos::Core::Backend::File


This variable decides how many seconds to wait between each user to connect to a chat server. The reason for this setting is that some servers will set a permanent ban if you “flood connect”.

Default: 3


Setting this variable to a true value will print extra debug information to STDERR. Another useful debug variable is MOJO_IRC_DEBUG which gives you IRC level debug information.


This variable is used by Convos::Core::Backend::File to figure out where to store settings and log files.

Default: $HOME/.local/share/convos/


This value can be used to specify where Convos should write the log messages to. This settings has no default value which makes Convos write the log to STDERR.


A list (comma separated) of perl modules that can be loaded into the backend for optional functionality.

There are currently no plugins loaded by default.


Can be used to set the address Convos will listen to from an environment variable.




The MOJO_REVERSE_PROXY environment variable can be used to enable proxy support, this allows Mojolicious to automatically pick up the X-Forwarded-For and X-Forwarded-Proto HTTP headers.

Note that setting this environment variable without a reverse proxy in front will be a security issue.
