The browser as creative runtime
Plate brings WebGPU motion design to the browser. Pencil's agents now build tools, not just designs. Cavalry is free. Midjourney V8.1 gets meaningfully faster.
WebGPU has unlocked something. The browser can now access GPU compute in a way it couldn't before, and a tool called Plate showed up this week to make use of it — a motion design application, v0↗.1 Alpha, Chrome only, running entirely in the browser with nothing to install.
Motion design has sat on the desktop for thirty years. After Effects. Cinema 4D. Cavalry↗. Professional motion work has always demanded real hardware and real software. Plate is a bet that WebGPU changes that calculus — that the browser can become the place where the work gets made, not just where it gets delivered. The bet is worth taking seriously even at this early stage. Browser-native creative tools tend to arrive rough, then quietly surpass their desktop counterparts in reach and collaboration. Figma↗ didn't arrive fully formed either. Plate was built by Marco van der Vlag and is available now at app.plate.video.
Pencil↗'s Code on Canvas takes a structurally different approach to the AI question. The idea isn't agents producing design — it's agents building the tools that produce design. Drop a Script node on the canvas, point it at a .js file, and Claude or Codex↗ generates a custom instrument on the fly: generative pattern brushes, live data components, color tools that don't exist yet. The canvas becomes extensible in real time, shaped by the task at hand.
Tom Krcha announced it on April 15. Pencil↗ already reached 100,000 users on SWARM mode — parallel agents designing in concert. Code on Canvas is the layer above that: agents aren't just working inside the tools, they're building them.
Cavalry↗ is free. After Canva's acquisition in February, the Manchester-built motion tool dropped its price to zero for individuals — full feature access, commercial use included, just a free Canva account required. If you do data-driven motion or generative animation, Cavalry↗ is now the most capable free tool in that space by a significant margin. Studios and teams still need a paid Canva license.
Midjourney↗ V8.1 landed at the end of April: HD mode is now 3x faster and 3x cheaper, standard resolution runs roughly 4x faster than V8, and the aesthetic reads closer to V7 — better prompt retention, more consistent style references. A quiet but meaningful improvement over V8's rougher edges.
