ENDOPHIN PROTOCOL™ - THE SYSTEM FOR CITIES THAT RUN TOGETHER
I built a live, global running protocol that turns solitary runs into a synchronized world movement.
What it is:
Endorphin Protocol is not an event, it's a system. Every weekend, cities run the same 5K at the same moment - FRI 19:00 + SAT 08:00, Global Sync FRI 06:00 GMT+6. Free. No fee. Every pace. The entire site runs on a live protocol database - the same record that reserves a spot, counts a city, and holds a moment. Nothing decorative. Live right now: 2,169 runners in the protocol (all time)Leading city: BERLIN (312) - live ticker City chapters: Lagos (98), Mexico (87), Sydney (76), Dubai (65), Chittagong (54), Dhaka (48)Open source runs, every weekend.
Why I built it:
Running apps charge you. Events are local. Endorphins should be free. I wanted a system where Mumbai, Berlin, Dhaka all feel like one team, running together, with real telemetry: NETWORK TELEMETRY, 5D 20H countdown, joined this week synced every 5s.Built with Base44:
Fully built on Base44 - live database, real-time counts, responsive desktop + mobile views, one-tap JOIN MUMBAI flow. No external paywalls.
The chemical is free. The system is global. #base44challenge @Base44

Northbound🚀: Studio Autopilot
An AI-powered client pipeline for creative studios, wrapped in a hand-built 3D world. A brief comes in, gets scored and routed, becomes a priced proposal, is accepted online and turns into a running project, with no one chasing emails.
Every studio knows the feeling: a new brief lands and the clock starts. Then come hours of reading, qualifying, writing proposals, chasing replies and setting up the project. Northbound turns that whole journey into one automated flow, so a small studio can respond like a big one.
The problem: Creative studios lose their best hours to admin. Strong leads wait days for a proposal, weak ones eat the same time as good ones, and follow-ups slip through the cracks. The work that wins clients is the work nobody has time for.
The solution:
- AI brief scoring and routing. Every brief is read for budget, timeline, goals and fit, then routed one of three ways: fast track, a quick human review, or an honest, helpful decline with pointers.
- Tailored proposals in about a minute. Strong fits get a scoped proposal with workstreams, a realistic timeline and three priced packages.
- Online acceptance and kickoff booking. Clients pick a package, accept online and book their kickoff call on the spot.
- A project that runs itself. Milestones are planned on acceptance, and follow-ups and reminders go out automatically.
- A morning digest. Every day at 08:00 the studio owner gets a summary of new briefs, proposals awaiting review, clients who haven’t replied, and what’s due.
- An owner dashboard showing pipeline, win rate and hours saved, plus a review queue to approve held proposals in one click.
- A live demo console where anyone can send a sample brief through the real pipeline and watch each step happen.
The morning digest is my favorite part here. When inquiries, proposals and deadlines are all in one place, you don't have to start the day searching through conversations. I'd just put the items that need an owner's decision today at the top.
Mega Submission!
Sector 7 Raceway is the site for a motorcycle circuit and track-day club, built to feel like an agency-made motorsport brand: a pitch-black bento-grid home, live track status and weather in the nav, and an interactive corner-by-corner track map.
I started with the photography, generating a consistent cast of riders and paddock scenes with a single photographic style lock, then wrote one detailed master prompt in Base44 covering the design system, every page, and the data model.
The pitch-black bento layout with the race photography is proper motorsport brand energy. Locking the photographic style first is a smart move, inconsistent imagery would have killed it. Did the interactive track map come from a Base44 data model, or did you hand-build that part?
Dear Guest, Entry 2: the same little Roman house, one week of work later.
I build booking websites for short-term rental hosts in Rome, and they all answer the same questions for every guest. Dear Guest turns those answers into five postcards the host writes once. Each guest gets a house of their own: every window is a postcard behind shutters until its day, the intercom ("Ask the house") answers from the host's own manual, and the shop next door sells the extras.
What's new since Entry 1, after an outside audit:
- The guest's essentials (door code, wifi, directions and a button to call the host) sit on an enamel sign on the roof. Each follows its postcard's rule: the code only appears on arrival day. After dark, a spotlight lights each compartment.
- The postcards got the most care: brighter colours, white icons, a perforated stamp, and a terracotta window box under each one that flowers once the guest has arrived.
- The front door has its number above the arch, a travertine step and a lantern that lights up at night.
- A real person is one tap away: call or WhatsApp the host, separate from the AI.
- When the house can't answer, the host replies to that guest on their own page; adding the answer to the manual for everyone is a separate choice.
- On wide screens the extras live in the bottega next door, a lit shop window with the extras on display.
- The host's post office opens on what needs them, and every figure says exactly what it counts.
- The street came alive (paper clouds, a cat on the roof, neighbours), and all of it can be paused.
What runs by itself: bookings sync every hour from Airbnb, Booking.com and Vrbo calendars; every morning a postman delivers the postcards that are due; "Ask the house" answers with AI from the manual only and never gives away the door code; every night the public demo moves to fresh dates.
Built on Base44: entities with row-level security per host, backend functions for the guest page, calendar sync, postman, AI answers and the public demo, 3 scheduled workflows, and a React front end designed around one idea: the page is the house.

The postcards are such a lovely mechanic. The terracotta window box that flowers once the guest has arrived is the kind of detail that turns a utility into something people remember. The fallback design is really well thought out too, a real person one tap away while adding an...
