Design one for a warung, restaurant or small business in the browser, then export it as a file you own. Exports to a single HTML file, a plain HTML and CSS folder, or a full React or Vue project. The two HTML formats ship no framework at all, just markup and about two kilobytes of vanilla script that keeps the open and closed badge, the today row in the hours table, and promo expiry honest. Eight templates and ten sections you can reorder or hide, live contrast ratios in the colour panel, and opening hours computed in the shop's own timezone including windows that cross midnight. Link previews and LocalBusiness JSON-LD are written into the exported HTML, because WhatsApp and Instagram never run JavaScript. No account and no backend, the draft lives in localStorage.

Nothing is uploaded, and it works offline. Your messaging app hands you a text file and a pile of numbered photos, and this turns it back into the conversation. The browser reads the dropped folder or zip straight from disk and makes no network request at runtime, not even for a font, so nothing leaves the device and nothing is kept. Installs as a PWA and still works with the wifi off. Handles iPhone and Android exports in any locale, parses 100,000 messages in about 110ms behind a virtualised list, and adds full text search, a per-participant media panel, and a replay mode that plays the conversation back message by message. - Link: https://replay.houseofky.xyz/ - Note: Live, source private - Tech: React 19, TypeScript, Tailwind v4, PWA, Web Worker, Virtualised List ### CVStudio **Type:** Web App A CV builder that runs entirely in the browser.

Five templates, drag and drop sections that work from the keyboard, and export to PDF, DOCX, plain text, or a JSON backup. No account and no backend, the document lives in localStorage and never leaves the device. English and Bahasa Indonesia. - Link: https://cvstudio.houseofky.xyz/ - Note: Live, source private - Tech: React 19, TypeScript, Tailwind v4, Zod, dnd-kit, PDF / DOCX ### Jejak **Type:** Full Stack PWA Employee attendance for businesses running more than one branch. Staff clock in from their own phone, and admins get the daily board, schedules and reports. The server checks the phone is inside the branch radius, then the staff member scans a rotating code at the counter. Admins also get weekly schedules, overtime to approve, and reports that export to CSV, Excel or PDF. White-label, so a customer's name, branches and rules are rows in a database and onboarding is a command rather than a fork. - Link: https://github.com/rbayuokt/jejak - Note: Open source, built for warungs and UMKM - Tech: React 19, NestJS, Postgres RLS, PWA, Tailwind v4, Docker ### Iris **Type:** Web Service Renders any URL in a real browser and hands back clean markdown, HTML, or structured JSON.
