I replaced my freelance SaaS stack with 5 single-file HTML tools

I noticed that as a freelancer I was paying several SaaS subscriptions just to handle simple tasks like invoices, proposals, contracts, and project tracking.

None of those workflows seemed complex enough to justify full SaaS platforms, so I started experimenting with local-first tools instead.

I ended up building five standalone HTML apps that run directly in the browser. No frameworks, no installation, and no accounts. Just open the file and use it.

The tools cover invoices, proposals, contracts, expenses, and project roadmaps. Everything runs locally and data stays on the machine.

Curious what others here think about local-first tools for this kind of workflow
