Welcome to the Pothos project
The Pothos project is a complete data-flow framework for creating topologies of interconnected processing blocks. Topologies can be designed and tested graphically, and deployed over a network. The Pothos framework API is sleek and smart, enabling users to quickly create custom processing blocks with minimal boiler-plate. Processing blocks can support computational offload and integration with DMA devices. The project also has a diverse set of processing and hardware support toolkits. Read more on the project overview page.

Pothos is a feature-full dataflow programming software suite.
- API to design data flows composed of modular blocks
- Graphical interface to design, deploy, and monitor
- Integration of 3rd party toolkits such as DSP libraries
- Support computational offload to GPUs, DSPs, FPGAs
- Custom processing blocks in any language (we have a binding for)
- Distributing across threadpools, processes, and nodes on a network
- Minimally invasive scheduler, minimal boilerplate for custom blocks
- See the Features summary page for more detailed information.
- See the Roadmap features page for future planned features.
Pothos can be built and installed on a variety of systems including Windows, OSX, and Linux. See the Build Guide for dependencies and compilation instructions. We have limited pre-built binaries available on the Releases page. If you would like get involved with providing distribution binaries, please contact us.
