 SpikeInterface is a Python package designed to unify preexisting spike sorting technologies into a single code base. If you use SpikeInterface, you are also using code and ideas from many other projects. Our codebase would be tiny without the amazing algorithms and formats that we interface with. See them all, and how to cite them, on our [references page](https://spikeinterface.readthedocs.io/en/latest/references.html). In the past year, we have added support for the following tools:
