Summary
steprs.dev parses STEP files entirely in your browser using WebAssembly. We do not upload, store, or process your CAD files on our servers.
STEP files
When you drop a file, bytes stay on your device. Parsing runs in a Web Worker with a local WASM engine. No cloud upload path exists in the production workflow.
Analytics
The public site does not load third-party analytics scripts. STEP file contents are never sent to analytics providers.
Private operator deployments may optionally enable aggregate page metrics via an environment flag. That data excludes file names, geometry, and parse output.
Hosting
The site may be hosted on a static platform. Standard web server logs (IP address, user agent, requested URL) may be retained by the host per their policies.
Open source
The Rust parser core is open source under Apache-2.0. The hosted application and editor are proprietary. See GitHub and the workbench.
