Paul Ford built an office app for hundreds of thousands of users — using only a web browser

How it works

A website for creating documents and spreadsheets that runs entirely inside your web browser with no downloads needed

1. 🌐Open any website with a web browser
2. 📝Write documents and spreadsheets right in the page
3. 🔗Share a link so others can see and use it
4. 🖥️Work on any device with no software installed

What you could do with it

• A writer who isn't technical could create spreadsheets and documents directly in their browser without downloading or installing anything ².
• Someone sharing files on a phone, tablet, or laptop could send a link where the document lives inside the URL instead of requiring recipients to log into a server ².
• A team across different devices and browsers could collaborate using the same app with no installs needed since it runs entirely in Chrome, Firefox, or Safari ².

An exampleInvented to explain it

Sarah texting a spreadsheet link to her coworker

SarahHere's the file. Just click the link.

MarcusDo I need to download anything?

SarahNope. It opens right in your browser.

MarcusWait, it's already editing? How does that work?

SarahIt's all inside the web page now. No install.

Marcus opened the document in his phone browser and started typing right away

A project that attracted hundreds of thousands of visitors

Last week Paul Ford and his team launched tinylittleoffice.com, described as "an office suite that stores data in the URL" — meaning documents live inside web links instead of hidden on a server somewhere else ².

Ford, who posted about his project on his own blog and whose words were shared by Simon Willison, said the response surprised him ¹². He originally estimated maybe a few thousand users, but a couple hundred thousand people visited within days .

The attention broke Cloudflare's free hosting plan almost immediately. After switching to a paid plan, Ford wrote, his monthly cost came to zero — partly because he optimizes for cheapness, but partly because hosting is just cheaper these days ².

"The web browser is very, very, very powerful software for building applications," Ford wrote in a post earlier this month ¹. "And the cost of accessing that power is going down seemingly every day." That line captured what most visitors found when they arrived at tinylittleoffice.com: a working spreadsheet-and-document experience inside Chrome, Firefox or Safari, with no install required ².

Why the timing felt right

Ford said the project started as something quick — basically "a fun thing" he built over a couple of weekends — but the feedback quickly pushed him to treat it as real software ².

Hacker News readers called it pointless at first; GitHub users opened feature requests and bug reports within hours ². Some of those requests were still open, he said, while others had already been shipped . The Register covered it, and it briefly reached the top ten on Product Hunt — a milestone Ford treated more as confirmation that enough people wanted exactly what he'd made .

Behind the simple interface sits a lot of browser platform that most consumers never see directly: the Web Crypto API for security, WebAssembly for speed-critical calculations, WebGL for rendering, and the Web Audio API for sound — all running inside whatever browser the user happens to have open on phone, tablet or laptop ².

What comes next

Ford announced he would continue supporting tinylittleoffice.com bit by bit while keeping his main client work steady ². He also pointed out that the project ships in 21 languages, including New York City's most common non-English ones — Creole and Yiddish — because accessibility means language too, not just captions .

For ordinary users, the takeaway is practical rather than technical: if you need a lightweight document or spreadsheet tool today, a web-browser version may already exist — and it could work on whatever device you wake up with tomorrow.
