pulsar
A free lossless compressor you run on your own machine. You get a Linux binary and the source. PCC is the hosted compressor: you send a file, we shrink it, you restore every byte later.
Dual license: GPL-3.0-or-later, or SKU pulsar-exception to ship it in a closed product. Release: github.com/ceedot-rock/pulsar-best v2.5.0.
To put pulsar inside a closed commercial product, pay $490/year (SKU pulsar-exception) for one product, one year. $199 support is help on top of that. Terms: COMMERCIAL-LICENSE.md.
