Tikal project downloads and usage is free of charge, and the
code itself is licensed under LGPL.
Tikal, a provider of open source tools for application manufacturing,
does offer enterprise level binaries, available for subscribers only,
that contain prepackaged and certified binary distributions
of open source products and technologies which are pre-integrated and pre
tested combinations of software components, alleviating the developer
and development manager from the need to allot resources to either
do all this alone or buy proprietary tools.
ISV teams and application professionals getting access to
subscriber-only binaries get packages containing pre-integrated
features and binary distributions, rather than snapshot versions
usually available for the public.
Tikal subscribers get full professional support for all tools available
through Tikal project.
