Open Source Browser Tools

Transparent tools that respect your privacy

We build free, open-source browser applications that are secure by design. No installations, no middlemen, and zero technical expertise required. Enjoy familiar web interfaces that just work out of the box.

Our Philosophy Read Perspectives

Secure by design. Private by character.

We build apps that empower you, not exploit you. Historically, open-source privacy tools demanded complex setups and technical know-how. We changed that. We wrap powerful, secure logic in beautiful, familiar UIs so anyone with a browser can use them instantly without writing a line of code. When our tools need to process data—like sending prompts to LLMs—they do it directly from your browser. There are no middlemen, no proxy servers storing your data, and absolutely no hidden tracking.

We believe the best tools are the ones you truly own — that respect your autonomy and adapt to your needs, not the other way around.

// No middlemen. No data hoarding.
// Direct connection from your browser.

const yourData = {
  location: "your device",
  shared: false,
  ownedBy: "you"
};

No middlemen. No stored data.

Our apps are transparent in how they work. When data needs to be sent to an external service (like an AI model), it goes straight from your browser to the provider. We never touch, store, or sell your data.

No Intermediary Databases

We don't store your inputs or outputs. Data only exists on your device and the necessary processing endpoints.

No Tracking, Ever

No analytics, no cookies, no fingerprinting. Just tools.

Auditable Code

Every line is public. Verify for yourself or fork it.

Voices that shaped the open movement

Leaders, thinkers, and hackers who understood that software freedom is fundamental to a free society.

In real open source, you have the right to control your own destiny. You can decide what features go in, and you can decide how the project evolves.

Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech,' not as in 'free beer.'

Given enough eyeballs, all bugs are shallow. The open source movement makes the debugging process parallel, harnessing the power of the community.

Open source is a development methodology; free software is a social movement. We stand on the shoulders of giants, building for the common good.

Zero setup. Familiar UI. It just works.

Open-source software shouldn't require a degree in computer science to run. Our apps feature the polished, familiar interfaces you expect from modern web tools. Just open your browser and start using them flawlessly out of the box.

01 Open the app directly in any modern browser
02 Connect directly to necessary services (like LLMs)
03 Rest easy knowing no middleman is storing your interactions

Frequently Asked Questions

Everything you need to know about our tools, our philosophy, and how we protect your data.

Q. Do I need to be a developer to use these?

Not at all. We believe privacy-first open-source software should be accessible to everyone. Our apps feature familiar, intuitive web interfaces and require absolutely zero technical expertise to run. If you know how to use a web portal, you know how to use our tools.

Q. What exactly do you build?

We build free, open-source applications that run directly in your browser. Unlike traditional apps, there is no centralized backend handling your data. Everything happens locally, ensuring maximum privacy and speed.

Q. Where is my data stored?

Nowhere but on your device. Specifically, your data lives securely in your browser's local storage. We never store, process, or sell any of your information on external proxy servers or databases.

Q. Do I need to create an account?

No. BrowserApps requires absolutely no accounts, no installations, and no downloads. Just open the tool in any modern browser and start using it instantly.

Q. What does "Bring Your Own API Key" mean?

For our tools that rely on AI (such as Large Language Models), you provide your own API key under your terms. Your browser communicates directly with the provider (e.g., OpenAI, Anthropic), meaning we never stand in the middle or intercept your requests.

Q. What browsers do your apps work on?

Our apps work with all modern browsers, including Chrome, Firefox, Safari, and Edge. Because sometimes browsers restrict local apps from certain features like using microphone or camera - you might need to use our hosted version or host it yourself on any web host.

Q. How secure are these apps?

They are secure by design. Centralized backends are targets for data breaches. By removing the backend component entirely, we eliminate the primary attack vector for data theft. Your data stays with you.

Q. Do they work offline?

Yes! For any functionality that does not inherently demand an internet connection (like querying an external API), our tools are fully capable of working offline. Once loaded, you can disconnect your Wi-Fi and keep working.

Q. How do you make money?

We take on custom development projects and sponsorships from companies and individuals who value our tools and want to support our mission.

Q. Are these tools really open source?

Absolutely. Our code is published under the MIT license. This means anyone is free to audit our source code to verify privacy claims, fork the repos to build their own features, or self-host everything. Transparency is core to our philosophy.
