Free developer trial

Start building, free

Three steps: install MoDeVa, claim a free 180-day developer key, and activate it. No credit card, no sales call.

Install MoDeVa

Demo mode runs immediately on built-in datasets — no key needed. The free developer key unlocks your own datasets.

$ pip install modeva

Every dependency is installed automatically — nothing to sort out by hand. If an import ever looks off, run modeva.check_dependencies() to check your environment and print the exact fix.

Claim your free key

Your free 180-day developer license is generated instantly and shown below in step 3.

One free 180-day developer license per email. No credit card.

Activate it

Set the key as an environment variable, or save it to ~/.modeva/license.key (%USERPROFILE%\.modeva\license.key on Windows). It's picked up automatically when you import modeva. Pick your platform:

# Current shell only
export MODEVA_LICENSE_KEY='modeva_live_…'

# Persist it (zsh — use ~/.bashrc on bash)
echo "export MODEVA_LICENSE_KEY='modeva_live_…'" >> ~/.zshrc

# Current session only
$env:MODEVA_LICENSE_KEY = "modeva_live_…"

# Persist it for your user account (new sessions pick it up)
[Environment]::SetEnvironmentVariable("MODEVA_LICENSE_KEY", "modeva_live_…", "User")

:: Current session only
set MODEVA_LICENSE_KEY=modeva_live_…

:: Persist it for your user account (takes effect in NEW terminals)
setx MODEVA_LICENSE_KEY "modeva_live_…"

# Writes ~/.modeva/license.key — works on every platform, and in
# Jupyter, where a shell variable set in another window is not visible.
from modeva.utils.authenticate import authenticate

authenticate(auth_code="modeva_live_…")

Your key appears here after you claim it in step 2.

An environment variable only reaches processes started after it is set — restart your terminal (and any Jupyter kernel) afterwards. The Python option writes the key to disk instead, so it needs no restart and behaves the same on every platform.
