London journeys, from wherever you already are.
A free Chrome extension. Find an address on a page, get a clear route across London — fastest, least walking, or step-free — with live arrivals and a word of warning when it is about to rain on your walk.
Six things, done plainly
- Reads the page you are on. Postcodes, stations, street addresses and landmarks become one-click destinations — only when you ask it to look.
- Three ways to travel. Fastest, least walking, or fewest changes. Switch between them and the results reload straight away.
- Step-free, up front. A single tick, not a setting buried three menus deep. Street to platform, platform to train.
- Live arrivals and disruptions. Straight from the TfL Unified API. The same numbers as the boards on the platform.
- Weather that knows your route. Ten minutes of walking and rain due? It says so, and points you at a route with less of it.
- Share the whole journey. Copy a readable summary or a link that reopens the route. Useful when someone is meeting you there.
Four steps, about a minute
While it is in testing you load it yourself. Nothing to compile, nothing to install first — Chrome 116 or later is all you need.
git clone https://github.com/wushu75/RouteWave.git
- Open chrome://extensions in a new tab.
- Turn on Developer mode, top right.
- Press Load unpacked and choose the folder you just cloned — the one with manifest.json inside.
- Pin it from the extensions menu, then press Alt Shift R.

What it never does
Most travel tools want an account first. This one has no account to make, because it has no server to make it on.
- No accounts, no analytics, no tracking
- Not a single third-party request. This page has none either.
- Your places stay on your machine
- Favourites, recent searches and settings live in your browser profile. Download or erase them whenever you like.
- Two requests leave, and you can see both
- Your search goes to Transport for London. A coordinate rounded to about a kilometre goes to Open-Meteo for the weather, and switching weather off stops even that.
- It reads a page only when you ask
- No background script on any site. What it finds stays in the popup and goes nowhere.
Read the full policy — it is short, and the source code backs up every line of it.
