I strongly encourage you to charge (lots) of money ASAP. I love the open source, offline, rent-free ethnos but also if you've built something truly valuable, charge money for it. Donations don't count as a viable monetization strategy.

Even if the software is free and you're just offering $500/hour consulting as an add-on to the software, that helps me trust the project has sticking power.

P.S. I think Tauri is such a cool framework and a delight to use. Rust's approach to platform-specific code is so much saner than anything I've tried previously.
