Shares Figma's exact problem: a vector canvas that renders smoothly and precisely is specialist rendering-engine work, not a weekend feature. Sketch just wraps it in a native Mac app instead of a browser tab.
VIBE SCORE 57/100
A moderate score here just means the individual parts are buildable — it isn't a build/buy recommendation on its own. Read "why CanICodeThis says Just pay" below for the actual reason this one's still JUST PAY.
The parts this build actually needs, each rated on its own — the average is the Vibe Score above.
| Landing page | 99 |
| Custom canvas/rendering engine | 15 |
Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $86–$172 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
Sketch costs $10/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 18 months.

Just pay. Shares Figma's exact problem: a vector canvas that renders smoothly and precisely is specialist rendering-engine work, not a weekend feature. Sketch just wraps it in a native Mac app instead of a browser tab.
Sketch costs $10/mo (about $120/yr) as of 2026-08. That's what a working rebuild would save you.
A performant native vector renderer with precise pen-tool bezier editing is the same order of engineering as Figma's canvas — this is exactly why that component exists in the database Their plugin ecosystem represents years of third-party developer investment Design system and component libraries with shared styles across a team are real, deep collaboration features
Yes — Inkscape are open-source options worth trying before you build your own. Details are in the standard parts section on this page.
