Level is an alternative to real-time chat designed for the software development workflow.
Sign up at level.app to reserve your handle and get on the updates list.
Level is currently in the pre-launch phase and under active development by a small team. Most tasks are being tracked offline as the foundations of the product come together, in the interest of rapid development and reaching an alpha stage for teams to start using it as quickly as possible.
As opportunities arise in the future for community contributions, we mark issues accordingly in the GitHub issue tracker.
You'll need to install the following dependencies first:
Run the bootstrap script to install the remaining dependencies and create your development database:
cd level
script/bootstrap
If your local PostgreSQL install does not have a default postgres user, open the config/dev.secret.exs file and update the credentials. Then, run the bootstrap script again.
Use the script/server command to start up your local server and visit localhost:4000 from your browser.
This repository includes a .nvmrc file targeting a specific version of Node
that is known to be compatible with all current node dependencies. Things might work
with a newer version of Node, but the most guaranteed route is to install
Node Version Manager and run nvm install from
the project root.
Then, be sure to run script/bootstrap to install node dependencies with the
correct version of node.
We have a handful of helper scripts available:
script/elixir-test: runs the Elixir test suite with coverallsscript/elm-test: runs the Elm test suitescript/test: runs the Elixir and Elm test suitesscript/static-analysis: runs Credo (Elixir linting), Dialyzer, and Elixir formatter verificationscript/build: runs all the test suites and static analysis

One of our goals is to make self-installation as painless as possible for those who are interested in hosting their own instance.
The relevant configuration files for Heroku live here:
We are aiming to keep seamless Heroku deployment up-to-date, with a few important "alpha software" notes:
- It's possible you may find it broken on master. If you do, please file an issue.
- As deployment needs grow more complex, it may become no longer feasible to support Heroku deploys. Caveat emptor.
In addition to a Heroku account, you'll need the following services to get your Heroku install up and running:
- An AWS account and an S3 bucket for storing file uploads. You'll be asked for AWS API keys and bucket name environment variables during setup.
- A transactional email provider (we recommend Postmark). You'll be asked for SMTP host, port, username, and password environment variables during setup.
