Frequently Asked Questions
Is everything really free?
Yes. Every free store is 100% free, forever. No trials, no limits, no "free for 7 days." The free tier never degrades. We have Pro stores ($9/month) for people who want server-powered features, but the free tools are complete on their own.
Do I need to create an account?
No. Every free tool works instantly — just open the page and use it. No email, no password, no signup. Some tools save your work in your browser's localStorage, but that's entirely on your device.
Do you collect my data?
No. We don't track you, don't use analytics, don't set cookies, and don't collect any personal information. Everything runs in your browser. Your data never leaves your device. We literally can't see what you do because we never look.
How do you make money?
Each free store has a Pro counterpart. Pro stores cost $9/month and offer server-powered features (AI agents, databases, campaign execution, marketplace access). Pro stores also have creator marketplaces where professionals offer services — the platform takes 10%. We don't show ads, ever.
Can I contribute a tool?
Yes! Every store has a CONTRIBUTING.md guide. The barrier is intentionally low: write a single self-contained HTML file, add a registry entry, open a pull request. Your tool goes live on the platform. All contributions are MIT licensed.
What technologies do you use?
Every tool is a single HTML file with inline CSS and JavaScript. No frameworks, no build step, no dependencies (except Google Fonts). Hosting is Cloudflare Pages. Backend services (for Pro stores) use Cloudflare Workers, D1 databases, and R2 storage. AI features use Chrome's built-in models (Nano) or the user's own API key.
Can I use these tools for commercial work?
Yes. All tools are MIT licensed. Logos you design, invoices you generate, code you format — it's all yours. Use it for clients, for your business, for anything. No attribution required.
What's the difference between free and Pro?
Free = browser-only tools. Everything runs on your device. No server, no account needed.
Pro ($9/mo) = server-powered features. AI agents that work for you, real-time collaboration, social media auto-posting, marketplace to hire professionals or offer your services, custom domains, team features.
Which AI do the tools use?
Tools that have AI features use Chrome's built-in Nano model (runs on your device, no data sent anywhere) when available. Some tools like the AI Content Writer can use your own OpenAI API key — the key stays in your browser's localStorage and is never sent to our servers. Tools always work without AI too — it's an enhancement, not a requirement.
How many stores are there?
Currently 26 stores covering: design, code, finance, robotics, quantum computing, blockchain, biology, chip design, space, marketing, music, writing, books, data, P2P networking, apps, games, websites, and AI agents. More are added regularly.
Is Open Frontier open source?
Yes. Everything is on GitHub across 25+ organizations. Every tool, every simulation, every store — MIT licensed. Fork the entire platform if you want.
Where can I find the documentation?
The full knowledge base is at openfrontier-docs.pages.dev. It includes architecture details, roadmap, per-store documentation, marketplace models, and decision logs.
I found a bug. How do I report it?
Open an issue on the store's GitHub repository. Every store page has a link to its GitHub repo. You can also fix it yourself and submit a PR — most bugs are in self-contained HTML files.
Can I use Open Frontier for my school/university?
Absolutely. The simulation stores (robotics, quantum, biology, etc.) were built specifically for education. Teachers can share direct links to simulations with students. No accounts needed, no IT department approval required. Works on any device with a browser.
