Open source.
Transparent by design.
Ready on your server.

Viper Suite is built around open-source transparency first: inspect the code, verify behavior, and deploy your way. Run it on your own infrastructure with full control over data and operations.

Optional: self-host in 3 commands
# clone the repository
git clone https://github.com/serpens-tech/viper-suite.git
cd viper-suite

# start everything
docker compose up -d

# then follow README for access and setup details

Everything you need to stay organised

Viper Suite ships with two apps that share one backend and database in a fully self-hosted setup.

Crossed Viper

Crossed Viper

Task & to-do management

  • Multiple task lists with priorities and due dates

  • Dark mode support (most important thing)
Leaf Viper

Leaf Viper

Income & expense tracking

  • Automatic entries from completed Crossed Viper finance tasks
  • Date-based transaction history

Run your own deployment in minutes

Running the server is recommended — it unlocks the full synergy between Crossed Viper and Leaf Viper, with shared accounts, automatic budget entries from completed finance tasks, and access from any client. All you need is Docker and Git.

If you prefer not to run a server, desktop and Android apps can store all data locally on the device as an alternative.
