MiCasa

Your browser's home page, and nobody else's business.

One HTML file. It opens with the time, the weather, the air you are breathing, your own news feeds, what is shaking near you and what is going to orbit next. Every byte of it is fetched by your browser, from public APIs, with no middleman. There is no account to make, no server behind it, and nothing anywhere that knows you were here.

The MiCasa board: a large clock with sunrise, sunset and moon phase, current weather with an hourly strip, air quality with a twelve hour trend, a wire of world headlines in three columns, local news, recent earthquakes, a launch countdown, and events from this day in history

The default board. Everything on it is live and everything on it is optional.

The Board

Eight modules. Keep the ones you want.

Each one loads on its own and fails on its own. A dead API costs you one card with a retry button, not a broken page.

Clock & Sky

Local time wherever you tell it you are, with sunrise, sunset, daylight remaining, a solar progress bar, and the moon's phase and illumination. Calculated on your device from your coordinates, so it keeps working with the network unplugged.

Weather

Current conditions and feels-like, the day's high and low, the next five hours, then wind, humidity, pressure, visibility, UV index and rain chance. From Open-Meteo, no key required.

Air Quality

US AQI with its category and dominant pollutant, a twelve hour trend drawn from real hourly readings, and the raw PM2.5, PM10 and ozone figures underneath.

World Wire

A lead story with its summary, then three columns of headlines. The feeds are entirely yours: add desks, name them what you like, and point them at any RSS or Atom URL.

Local News

Headlines for the actual town your location resolves to. Give it a postal code and it narrows from the metro area to your side of it.

Hazards

Every magnitude 2.5 and up in the last twenty four hours, worldwide, with depth and how far it was from you. Plus any active weather alerts for your exact coordinates.

Space Launches

A live countdown to the next orbital launch with vehicle, payload, pad and window, and the three flights queued behind it.

On This Day

Selected events for today's date, each linking to the full account.

Add your own

The whole thing is one readable file with no build step. If you want a ninth module, the eight in front of you are the worked examples.

Type, hit Enter, go.

No browser lets a web page drive its own address bar, so MiCasa does the honest thing and hands your query straight to a real search engine. Enter goes to Google by default, or to DuckDuckGo, Bing, Brave, Startpage, Ecosia, Kagi, Mojeek or any URL template you supply. Scope chips send it to images, news or video instead.

A leading ! routes around the engine entirely. !yt for YouTube, !w for Wikipedia, !gh for GitHub, !so, !npm, !crates, !maps, and a dozen more. Paste a URL and Enter just goes there. Suggestions complete as you type, and switching them off means nothing is requested.

Type 20 c to f or (1920*1080)/1000 or 26.2 mi to km and the answer appears above the results before you have finished. That runs on your machine with a hand-written parser. No request goes out, and none needs to.

Nerd Search

The one search that stays on the page.

Every keyless web index either refuses to talk to a browser or matches too loosely to be worth showing, so MiCasa does not pretend otherwise. What a browser can query directly is the developer indexes, and those it queries in full.

Nerd Search results for rust async runtime, showing grouped results from Stack Overflow, Hacker News and GitHub in the main column with package registry hits and a CVE listed alongside

One query, ten indexes: Stack Overflow, Super User, Hacker News, GitHub, OpenAlex, the NVD, npm, crates.io, PyPI and Packagist. No key, no relay, no server.

Customization

Genuinely everything.

One panel, everything in it, saved the instant you touch it. No profile, no sync, no "upgrade to customize".

The Customize panel, open on the default board.

Customization

What you can change.

Thirty-one themes

Across five families: House, Dark, Retro, Light and Mono. Solarized in both directions, Gruvbox, Dracula, Tokyo Night, Nord, Deep Sea, Plum, Rust, Cobalt, Blueprint, Matrix, Amber CRT, Phosphor, VT220, Paper, Newsprint, Linen, Sepia, Clinical. Each brings its own palette, type pairing, corner radius and background. Filter the gallery to dark or light only.

Overrides on top

Twelve accent colours, ten typeface pairings, four corner radii, and eight animated canvas backgrounds: constellation, grid, dot matrix, scanlines, starfield, code rain, contours, or nothing at all. Layer them over any theme, then clear them in one click to get the theme back as shipped.

Layout

Three presets that genuinely rearrange the board rather than hiding cards, each carrying its own per-module widths. News Desk runs the wire across the top. Weather Forward leads with sky and air. Everything On packs all eight in at maximum density. Then add and remove modules from the board itself.

Location

City name, or a postal code resolved to the delivery area across about forty countries, or the browser's own position if you would rather ask it. Saved locations become one-click chips. Your choice drives the clock's timezone, weather, air quality, sun times, quake distances and the local news desk.

Feeds

Add, rename and delete desks. Put any number of RSS or Atom URLs under each. Point local news at your own sources instead of the automatic ones. Pick which public CORS relay fetches them, or supply your own URL template.

The details

Fahrenheit or Celsius. mph, km/h, m/s or knots. inHg or hPa. Miles or kilometres. Twelve or twenty four hour clock. Refresh anywhere from five minutes to three hours. Export the lot to a JSON file and import it on another machine.

Customization

The same page, wearing something else.

The Point

No ads. No tracking. Not ever.

Every other start page is an advertising surface wearing a clock. This one is a file.

No ads. Not now, not later, not "tasteful" ones, not after some funding round. There is no ad slot in the markup and there will not be one.
No sponsored posts. The wire shows the feeds you listed, in the order they were published. Nobody can buy a spot in it because there is nobody to pay.
No analytics. No Google Analytics, no Plausible, no pixel, no beacon, no error reporter, no heatmap, no session recorder.
No account. Nothing to sign up for, nothing to log into, no email address to hand over, no password to have breached.
No cookies. MiCasa sets none. There is no consent banner because there is nothing to consent to.
No server. This is the part that matters. There is no backend anywhere. Even if we wanted your data there is no machine on our side that ever sees it.
No record of anything you do. What you search, what you read, what you click, where you are: none of it is stored anywhere except your own browser, and none of it is transmitted to us, because there is no us to transmit it to.

What actually leaves your browser

Being straight about it, since "no tracking" is a claim anyone can print. MiCasa makes exactly the requests you would make yourself:

Your coordinates go to Open-Meteo, because that is how you ask for weather at a place.
Your feed URLs go to a public CORS relay, because RSS publishers send no CORS headers and a page with no server cannot fetch them any other way. Which relay is your choice, including your own.
Your search query goes to the engine you picked, at the moment you press Enter. That is the handoff doing its job.
Keystrokes go to Google's public autocomplete endpoint while suggestions are on. One switch turns that off for good.

That is the entire list. Settings and cached responses sit in localStorage on your machine under micasa.prefs.v1. The file is 150 KB of readable HTML with one inline script and no dependencies, so none of this has to be taken on trust. Read it.

Setup

Make it your home page.

Paste this address wherever your browser asks for one.

https://www.lockewerks.com/micasa/app

Chrome and Edge

Settings, then On startup, then Open a specific page or set of pages, then Add a new page. Paste the address. To put it on the home button too, turn on Show home button under Appearance and paste it there as well. Chrome does not let a website claim the New Tab page on its own, so that one needs an extension.

Firefox

Settings, then Home. Set Homepage and new windows to Custom URLs and paste the address. Set New tabs to Custom URLs and paste it again, and Firefox will use it for every new tab.

Safari

Settings, then General. Paste the address into Homepage, then set both New windows open with and New tabs open with to Homepage.

Phone or tablet

Open it, then Add to Home Screen from the share menu. It launches full screen with no browser chrome, and the layout collapses to a single column on its own.

As your search engine

MiCasa answers a query handed to it in the URL, so your address bar can land here first. Add https://www.lockewerks.com/micasa/app#q=%s as a custom search engine under Settings, Search engine, Manage search engines in Chrome or Edge, or as a keyword bookmark in Firefox. Append &scope=nerd to send everything straight to Nerd Search.

Your own copy

Download micasa.html and open it from your desktop, or drop it on any static host. It runs from file:// with no web server at all. Settings are keyed to the exact path, so pick a home for it and leave it there. Rename it to index.html if you are serving it from a directory root.

At phone width the board collapses to one column on its own. Nothing is hidden and nothing needs a separate mobile build.

Every one of these is free, needs no API key, and is contacted by your browser directly.
