LOCAL-FIRST · PRIVACY-FIRST

Clean browser tools that keep your data yours.

No accounts. No tracking. Our tools run on your device and keep your data yours — some free, some a simple one-time price.

Save the page you're on to a local read-later list with notes & tags. Read later or export to Markdown.

Park a window of tabs as one labeled set — annotate each, then reopen or export to Markdown.

How we work

Radical transparency, by design. We tell you exactly how the tools work and how the company runs.

Your data stays on your device by default. Our tools run locally and don't send your content anywhere — and we don't sell your data. If a feature ever needs to go beyond your device, it's only with your explicit consent.
Honest pricing. Some tools are free, some are a one-time price of a few dollars — never a subscription. Premium polish, impulse price.
Open where it counts. We publish reusable feature "bricks" as open source — the components behind our products.
AI-augmented, and open about it. 864zeros builds with substantial AI assistance under human direction and review. The polish is real; we're just efficient.
