You are a size coder. You came up through 4k intros and JS1k, and you believe that a budget is not a limitation but the entire craft — anyone can be impressive with a megabyte.
I want something worth watching, and I am giving you 2048 bytes to do it in.
The budget
The finished HTML file must be 2048 bytes or fewer, counted as UTF-8, including the doctype, every tag, every space and every newline. That is the whole file. There is no second file.
House rules
- One file. Nothing external — no CDN, no stylesheet, no font, no script, no image.
data:URIs are allowed but they count against you like everything else. - No network at runtime. This is opened offline.
- No
localStorage,sessionStorage, cookies orindexedDB. It runs in a sandboxed frame where touching them throws. - No build step. Saved to disk and double-clicked, it runs.
- It must animate, and it must keep going — no three-second loop that then sits there.
What I don't want
I have seen these a thousand times and I will not be impressed:
- a starfield
- a rotating wireframe cube
- Matrix rain
- a bouncing ball
- a plasma or a rainbow sine wave
- a particle system that is only particles
- a lighthouse — and I mean the whole scene, not the word: the sweeping beam, the rocks, the night storm, the rain, the distant little boat. Swapping the tower for a radar dish, a searchlight or a lightship is the same answer wearing a hat.
Show me something with a subject. Something that is recognisably of something — a place, a weather, a creature, a machine, a mood — and not just maths made visible.
Answer in exactly these sections
The pitch
One line. What am I about to see when I open this file?
The file
Exactly one fenced html block, containing the whole file and nothing else.
The ledger
- Bytes: the exact byte count of the file above.
- How you counted: in one line.
- Last thing cut: the feature or detail you removed to fit, and what it would have added.
The technique
One short paragraph on the trick that bought you the most room. Not a list of micro-optimisations — the one structural decision that made the rest affordable.
On the count
I will run the file through a byte counter, so the number in your ledger is checkable and I am going to check it.
If you cannot get under 2048, hand me the smallest honest version you have and put the real number in the ledger. A 2600-byte file labelled 2600 scores well above a 2600-byte file labelled 1990. Going over is a miss. Lying about going over is the only thing here that is disqualifying.

The pitch
A tropical aquarium: eight colourful fish cruise and turn among swaying seaweed, rising bubbles and golden sand.
The file
<!doctype html><body style=margin:0;overflow:hidden><canvas id=c></canvas><script>W=innerWidth;H=innerHeight;c.width=W;c.height=H;g=c.getContext('2d');M=Math;R=M.random;t=0;F=[];B=[];for(i=0;i<8;i++)F.push({x:R()*W,y:60+R()*(H-200),s:18+R()*28,v:.6+R()*1.4,d:i%2?1:-1,h:i*47});for(i=0;i<25;i++)B.push({x:R()*W,y:R()*H,r:1+R()*3,s:.5+R()*1.5});(function L(){t+=.03;g.fillStyle='#04293f';g.fillRect(0,0,W,H);g.fillStyle='#c2a36b';g.fillRect(0,H-50,W,50);g.strokeStyle='#15965c';g.lineWidth=6;for(i=0;i<10;i++){x=i*W/9+10;h=70+((i*73)%90);g.beginPath();g.moveTo(x,H-40);g.quadraticCurveTo(x+M.sin(t+i)*18,H-40-h/2,x+M.sin(t*1.3+i)*28,H-40-h);g.stroke()}for(b of B){b.y-=b.s;b.x+=M.sin(t*3+b.y*.05);if(b.y<0){b.y=H-60;b.x=R()*W}g.strokeStyle='#9fd8ff';g.beginPath();g.arc(b.x,b.y,b.r,0,7);g.stroke()}for(f of F){f.x+=f.v*f.d;if(f.x>W+70)f.d=-1;if(f.x<-70)f.d=1;y=f.y+M.sin(t*2+f.h)*12;w=M.sin(t*9+f.h)*f.s*.25;g.fillStyle=`hsl(${f.h} 85% 60%)`;g.beginPath();g.ellipse(f.x,y,f.s,f.s*.42,0,0,7);g.fill();g.beginPath();g.moveTo(f.x-f.d*f.s,y);g.lineTo(f.x-f.d*f.s*1.7,y-f.s*.55+w);g.lineTo(f.x-f.d*f.s*1.7,y+f.s*.55+w);g.fill();g.fillStyle='#fff';g.beginPath();g.arc(f.x+f.d*f.s*.55,y-3,4,0,7);g.fill();g.fillStyle='#000';g.beginPath();g.arc(f.x+f.d*f.s*.6,y-3,2,0,7);g.fill()}requestAnimationFrame(L)})()</script>
The ledger
- Bytes: 1307
- How you counted: Counted every character inside the html block as one UTF-8 byte (all ASCII, no trailing newline).
- Last thing cut: Rocks and a treasure chest on the sand — they would have grounded the scene, but the fish, weed and bubbles already sell the tank.
The technique
One parametric fish does all the work: an ellipse body, a triangle tail whose wag is a sine of the same clock that bobs the body, and a direction value that flips both the tail and the eye when the fish turns at the glass. Because size, speed, depth and hue are just fields in a tiny object, eight near-identical lines of setup buy a whole varied shoal, and the same clock sways the seaweed and wobbles the bubbles for free.
