News & Updates

Nine new POLPROG web apps from the May series are now live. They cover three areas - interactive visualizations, community portals, and browser experiments - all built in-house, privacy-first, with no accounts and no third-party tracking.

This release closes the chapter teased last week and brings every project from preview to production. Each app is self-contained, free to use, and focused on a single, well-defined purpose.

Interactive visualizations

Three projects that turn invisible processes into something you can actually look at and explore.

1. FlowTrace - shows what actually happens behind a click, keypress, form submit or scroll. The visualization walks across browser, JavaScript runtime, network, server, cache, queue, database and render, so the full request lifecycle becomes obvious at a glance.
2. MusicDNA - turns any song into visual DNA. Pick a local audio file and the app analyzes rhythm, energy, spectrum, harmony, structure and dynamics, then renders interactive visualizations on top of the result.
3. PageDNA - turns any website into visual DNA. Analyzes structure, style and behavior directly in the browser, with a small Playwright backend powering URL mode for sites that would otherwise be blocked by CORS.

Community portals

Three knowledge hubs built around real passions. Each one organizes content, events and resources for a specific community.

1. AeroCraft - portal about aeromodelling in Poland. Encyclopedia of model classes, guides and knowledge base, competition calendar, clubs and shops directory, model tools and an admin panel for the editors.
2. BikeAtlas - web project around cycling, focused on routes, places and community resources. Scope, data sources and map features are verified directly against the project repository.
3. GuitarAtlas - reference and exploration project around the guitar: instruments, players, scales and gear. The content set keeps evolving, with every change tracked against the project repository.

Browser experiments

Three projects that take the web in a less obvious direction - a logic puzzle, an anonymous tab diary and a full retro time capsule.

1. Axiom - a browser merge puzzle where you combine same-colored tiles, charge them and trigger explosive chain reactions. It offers five solo modes, a shared daily challenge, a 3D board, achievements, a leaderboard and multiplayer duels.
2. MyLastTab - anonymous browser-tab diary. Users submit one short description of their last open tab. No accounts, no logins, no screenshots - just live entries, hourly stats and a 3D city built from submissions.
3. WelcomeTo1997 - interactive time capsule of the 90s web: dial-up boot sequence, retro portal, Windows 95 style desktop and mini-apps like Winamp, ICQ, Netscape, guestbook, Cool Links and a 56k download zone.

What all nine share

1. No accounts required. Open the URL, start using the app. No email, no sign-up, no login.
2. No third-party tracking. No Google Analytics, no Hotjar, no marketing pixels - only the privacy-respecting basics POLPROG already uses across the site.
3. Offline-first where it makes sense. Visualizations and tools that can run client-side do so; community portals stay reachable even when individual data sources hiccup.
4. Built and maintained in-house. Every project is part of the same POLPROG codebase, with the same release process, the same accessibility baseline and the same WCAG-aware components.

Nine apps, three themes, one release. All live today, all free to use.
