Try everything first. Pay when you ship.
The two libraries ship as one download, and no license is needed to use them. What you pay for, when you ship, is how it runs: a developer seat, a product you ship, a server, or a website. Students and schools pay nothing. Every license comes with support: by email at info@blitter.studio, and in a private channel on our Discord.
No license, no time limit, nothing missing
Unlicensed, every library runs in full: every reader, the mesher, the kernel, the exports. The only difference is a one-line notice printed to stderr each time a file is opened and each time a mesh or a STEP file is written. Evaluate for as long as you need; buy a license when you ship, and the notice goes away.
From the SDK checkout, python fetch.py pulls the libraries, headers and samples for your machine; wrappers for Python, C#, Go, Java, Node.js, Rust, Swift and LuaJIT are in the same repository.
For developers
A seat covers one developer: their own workstations, their internal tools, and the build and test automation of the applications they work on. The quantity at checkout is the number of seats, and volume is priced in at checkout: from 10 seats every seat is 10 % off, from 20 seats 15 %, from 50 seats 20 %.
€90 per seat, per year
The readers for seven formats, the mesher, levels of detail, and the exports to STL, glTF, OBJ and Gmsh MSH: everything to get geometry in and triangles out.
Buy Reader€170 per seat, per year
Everything in Reader, plus the exact modelling kernel: booleans, fillets, shells, sweeps, lofts and the STEP writer of the blacksmith.
Buy ProFor what you ship
An application you ship to end users with cadaclysm inside — desktop or mobile, on every platform, in every version, any number of installs — needs a product license, one per application, beside the seats of the people building it. The quantity at checkout is the number of products.
If a flat yearly fee does not fit your product — you are starting out, or your volume is uncertain — we are open to a revenue-share arrangement instead. Write to info@blitter.studio or ask on Discord.
€4,000 per product, per year
Import inside your application: the readers, the mesher, levels of detail and the exports, royalty-free.
Buy Product Reader€6,500 per product, per year
Import and the kernel inside your application: everything in Product Reader plus the blacksmith, royalty-free.
Buy Product ProFor machines that work unattended
A server is any machine that opens or processes files unattended on behalf of other users or systems: a web service or API, a conversion or ingestion pipeline, a batch job, a render or processing farm, whether physical, virtual or a container host. Each such machine needs a server license. The quantity at checkout is the number of servers.
€5,000 per server, per year
Import on a server: the readers, the mesher, levels of detail and the exports.
Buy Server Reader€8,000 per server, per year
Import and the kernel on a server: everything in Server Reader plus the blacksmith.
Buy Server ProFor the browser
The reader and the blacksmith also run as WebAssembly — the viewer and the forge on this site are them. Embedding those builds in a website that others use needs a web license per website: a domain and its subdomains. The quantity at checkout is the number of websites, and checkout asks for their domains: the license names them, and the builds hold to them. Each release carries both packages — the module with its typings, the WebGL2 viewer and an example page; how to embed them.
€3,000 per website, per year
Import in the browser: the readers, the mesher and the viewer, as WebAssembly in your page. Files never leave the visitor's machine.
Buy Web Reader€5,000 per website, per year
Import and the kernel in the browser: everything in Web Reader plus the blacksmith — what the forge runs on.
Buy Web ProFree for education
Learning, teaching or research at a school or university: a full Pro license, free, for a year at a time. It is not bought here — write to info@blitter.studio from your institutional address, say who you are and what you are working on, and we issue it by hand. For a class, one license covers the whole class.
Enterprise and source
More seats, a move from Reader to Pro, or a cancellation: the customer portal on the licenses page prorates the difference. An enterprise agreement, or access to the Rust sources: write to info@blitter.studio.
