We build browser tools that keep your work private.
Smart Build Labs is an independent studio. We make browser extensions that do one job properly, run on your own machine, and do not ask you for an account.
What we make
Two products, actively maintained.
How we build
The constraints we hold ourselves to.
Processing stays on your machine
Where a tool needs to understand your data, it does that in your browser. We do not run it through a server, because we would rather not hold it.
No account to use the thing
Installing is enough. We do not need an identity to make a browser extension work, so we do not ask for one.
Pay once where you pay at all
Paid features are a one-time purchase. A small tool should not become a subscription.
