Our verdict on Vertessia
Vertessia is a web-based 3D geometry toolkit for converting mesh and CAD files in a browser. It supports STL, OBJ, PLY, 3MF, GLB, glTF, and STEP, including STEP-to-mesh conversion. Its audience includes makers, reverse engineers, scanning services, developers, and enterprise users who need a focused conversion workspace rather than a full desktop modeling application. The interactive 3D preview and adjustable mesh triangulation settings make it suited to inspecting and refining conversion output before moving files into another workflow.
The free plan provides unlimited mesh conversions, instant 3D preview, and three reconstruction trials per month at launch. According to the published plans, Maker costs $19 per month and adds 30 reconstructions monthly, no watermark, and support for large files. Pro costs $79 per month with 200 reconstructions, batch upload, and a priority queue. Team costs $249 per month and includes 1,000 reconstructions, five seats, and API access. The service is in early access, and the paid tiers are listed as coming soon, with payments currently in test mode.
Vertessia’s current scope is narrower than its longer-term roadmap. Mesh conversion, STEP-to-mesh conversion, preview, and triangulation controls are available capabilities, while mesh-to-editable-STEP CAD B-rep reconstruction, additional mesh-processing algorithms, and the usage-based REST API with webhooks are planned. That makes Vertessia a sensible choice for users who want browser-based conversion across common formats and can work within an early-access product. Users who need current CAD reconstruction, production API integration, or a mature desktop tool should choose an alternative until those capabilities are available.
