Spline review

Spline is a 3D editor for building interactive scenes and publishing them to websites and apps. Its tools cover modeling with primitives, booleans, sculpting and 3D generation; materials and lighting; and animation and interaction through states, keyframes, events and physics. Teams can work in the same editable file, with options to comment, undo or take over, according to the product description.

Spline also supports AI agents that use MCP to read and edit scenes. That makes it more than a viewer or a way to embed a finished model: the core offer is an editable workflow from scene creation through publishing. The product description lists publishing to the web and building native apps for iOS and Android. For marketers, the fit is interactive 3D content; it is not presented as a general-purpose design or analytics suite.

Spline puts scene creation and interactive behavior in one editor. The listed tools span basic modeling through lighting, materials, animation and physics, so a team can build a scene and define how it responds without stitching together separate products for each step. Teams can also work in the same live file, with commenting and handoff options described in the product materials.

Publishing choices are another practical advantage: the product description covers web publishing and native iOS and Android apps. AI agents that speak MCP can read and edit scenes, which may suit teams already using agent workflows. The pricing page lists 20 MCP calls a day on Free, rising to 100 on Hobby, 200 on Pro and 400 on Max or Enterprise.

Hobby is the first paid plan with unlimited 3D and 2D files and watermark-free web exports. It costs $12 per seat per month with annual billing, or $15 month to month, according to the pricing page. That gives individual creators a clear paid step up from the watermarked Free exports.

Free is useful for exploring, but its limits matter if the output is going live: the plan includes limited personal files and watermarked web exports, plus 20 MCP calls a day. Removing the web-export watermark means paying at least $12 per seat per month on annual billing ($15 monthly), per the pricing page.

Team features and export options sit higher up the price ladder. Pro is $25 per seat per month annually or $30 monthly, and adds video export, unlimited folders and projects, 3,000 AI credits per seat monthly and 200 MCP calls a day. Max costs $60 annually or $70 monthly, with 10,000 AI credits, 400 MCP calls a day, five times more media generation per week and a 100MB maximum video size. Hobby and Pro cap additional AI credits at 10,000; Max caps them at 20,000. Extra credits cost $5 monthly per seat per 1,000, or $48 per year. Enterprise pricing is custom. A Reddit thread also describes leaving over a $20 monthly fee, but that anecdote does not establish current pricing.

Spline’s free plan costs $0, but includes limited personal files and watermarked web exports. Hobby starts at $12 per seat per month when billed annually, or $15 monthly. That gets you unlimited 2D and 3D files, watermark-free web exports, 2,000 AI credits and 100 MCP calls per day.

Pro is $25 per seat per month annually, or $30 monthly. The jump from Hobby is $13 per seat monthly on annual billing; Pro adds 3,000 AI credits, 200 daily MCP calls, unlimited folders and projects, and video export. Max costs $60 annually or $70 monthly, adding 10,000 AI credits, 400 daily MCP calls and a 100MB video-size limit.

Extra AI credits cost $5 per month per seat per 1,000, or $48 per year. Hobby and Pro cap at 10,000 credits; Max caps at 20,000. Enterprise pricing is custom and billed annually. Check the billing basis before budgeting: listed paid annual prices are per seat, and team costs rise with headcount.

Moving to Spline means building or recreating interactive 3D scenes in its editor; the published information does not describe an import path from other 3D tools. It supports modeling, materials, animation and physics, with publishing to web, iOS and Android. But export and portability details are limited here: web exports are watermarked on Free, while Enterprise lists self-hosted exports. The sources do not say whether editable scenes can be exported in a portable format, so check that before making Spline the only home for production files.

Leaving may also mean replacing workflows built around live collaboration or MCP-connected agents; the available information does not document how those workflows transfer. We can’t attribute reasons for leaving to Reddit because no Reddit posts or comments were included in the published material. The clearest documented reasons to reconsider are the per-seat paid plans, caps on AI credits and MCP calls, and the lack of public Enterprise pricing. Ask Spline about file portability and migration before committing a team.
