Spline

Let's be direct: Spline has carved a niche that Blender and other heavy 3D tools ignore—web-native, real-time, collaborative 3D that designers can actually ship without waiting for a developer. The Omma AI agent is the headline: describe a scene or app idea, and it spawns code, image, and 3D generation to produce a structured experience. That's not just a demo trick; in practice, it cuts the time from concept to a workable interactive prototype dramatically. When should you pick Spline? If you're a designer or marketer who needs interactive 3D for a website, product mockup, or brand asset—and you want it done in a browser, with teammates in the file at the same time—Spline is arguably the best fit. The Hana 2D canvas adds infinite canvas, auto layout, and vector networks, plus fill-to-3D and copy-paste from Figma, so you can move from wireframe to polished 3D without switching tools. The real-time collaboration is genuinely useful; comments, invites, and shared links keep stakeholders in the loop. Where it bites: Spline is not for high-end VFX, offline rendering, or complex character rigging for games—Blender is still the tool there. It's also not a substitute for CAD or parametric modeling. The free tier is generous but watermarks exports; serious production requires a paid plan. Enterprise needs like on-premise hosting or air-gapped environments aren't supported. Compared to Blender, Spline trades depth for accessibility and speed. Blender has a steep learning curve and lacks built-in web exports and AI scene generation. For most design teams building web experiences, Spline is the pragmatic choice. If you need cinematic VFX or film-TVR rendering, stick with Blender. One caveat: the AI credits system can gate Omma's use on lower tiers. Hobby gets 2,000 monthly
