Spline vs Cursor
Side-by-side comparison of AI visibility scores, market position, and capabilities
SF/Chile YC W21 browser-based collaborative 3D design platform at $32M total ($16M Third Point/Gradient Series A Jun 2024) and $55M valuation; no-code 3D for web/app/game competing with Rive and Blender for interactive 3D content creation.
About
Spline is a Santiago, Chile-founded (now San Francisco-based) collaborative web 3D design platform — backed by Y Combinator (W21) with $32 million in total funding including a $16 million Series A in June 2024 led by Third Point Ventures with participation from First Round Capital, Gradient Ventures (Google's AI fund), and YC — providing designers and developers with a browser-based 3D design tool for creating interactive 3D experiences, game elements, product configurators, and motion graphics without writing three.js or WebGL code. Founded in 2020 and reaching a $55 million valuation in July 2023, Spline serves the growing community of web designers who want to incorporate 3D interactive elements (spinning product models, 3D landing page heroes, animated 3D icons) into websites and apps through a no-code visual editor with real-time collaboration.
In talks to raise $2B at $50B valuation in Apr 2026 (Thrive, a16z, Nvidia). $2B+ ARR; revenue projected >$6B by EOY 2026. Used by 50%+ of Fortune 500.
About
Cursor is an AI-first code editor founded in 2022 by a small team of MIT researchers, built as a fork of Visual Studio Code with native large-language-model intelligence woven directly into the editing experience. Its mission is to make software engineers dramatically more productive by embedding AI reasoning into every layer of the IDE — from autocomplete to multi-file edits to natural-language code generation — rather than bolting AI on as an afterthought.\n\nThe platform centers on a VSCode-compatible editor that developers can adopt with zero workflow disruption, layering in features like Tab (predictive multi-line completion), Chat (context-aware in-editor assistant), and Composer (autonomous multi-file refactoring agent). Cursor reads and indexes entire codebases, allowing it to propose changes that span dozens of files coherently. It supports all major languages, integrates with existing extensions, and lets teams configure which underlying model — GPT-4o, Claude, or others — powers suggestions. Fortune 500 engineering teams adopt it alongside individual developers, and it is used by more than half of Fortune 500 companies.\n\nCursor reached $2 billion in annualized recurring revenue by early 2026 and raised at a $29.3 billion valuation, cementing its position as the dominant commercial AI coding tool. The company raised $2.3 billion in total funding and is widely regarded as the category-defining product in agentic IDE software, outpacing GitHub Copilot on developer mindshare metrics in multiple surveys.
