No account. No download. No paywall. Click, use it, done. Every app works instantly in your browser.

Sponsors keep it free
Brands sponsor build100. You never pay, never see ads inside the apps. That's the deal. That's always the deal.
Questions
FAQ

Yes. Always. The revenue model is sponsorships — brands pay to be featured on the site, not inside your experience. You will never hit a paywall on build100.

No. Zero accounts. Zero logins. Zero cookies. You open the app, use it, and leave. We don't know who you are and we don't need to.

2 apps per week, 50 weeks. Each one is a focused tool that solves one specific problem. We build in public — follow on YouTube to see the full process.

Everything runs in your browser session. We don't store your salary data, your resume, your photos, or any inputs. The AI processes your request and that's it — gone.

Yes — DM us on Instagram @build100tech. If enough people want it and it solves a real problem, it gets built.
