WhatA cleanroom open-source geometric modeling kernel with Parasolid-compatible behavior, offered as a commercial-friendly library for CAD tool builders.
SignalA commenter directly asks whether an open-source Parasolid replacement exists, and the broader thread reveals that every open-source CAD project struggles with the same problem — the underlying geometric kernels are either proprietary, incomplete, or poorly maintained, forcing each project to reinvent the wheel.
Why NowThe explosion of browser-based and AI-powered CAD tools all need a reliable geometric kernel, but Open CASCADE is aging and notoriously hard to work with, creating demand for a modern, developer-friendly alternative.
MarketCAD software companies, robotics firms, and hardware startups building custom tools; Siemens licenses Parasolid for ~$50-200 per seat; a modern OSS kernel with commercial support could capture the long tail of smaller tool builders.
MoatExtreme technical depth — building a production-grade B-rep kernel takes years and deep computational geometry expertise, creating a massive barrier to entry that few teams can clear.
Automated Supply Chain Attack Detection for Package RegistriesP7/10A real-time monitoring service that detects compromised packages on npm, PyPI, crates.io, and other registries by analyzing behavioral anomalies like credential-bypassed publishes, injected phantom dependencies, and suspicious postinstall scripts.
Zero-Trust Dependency Firewall for Development EnvironmentsC7/10A local proxy that intercepts all package installs, enforces configurable quarantine periods, blocks postinstall scripts by default, and provides a unified policy layer across npm, pip, cargo, and Go modules.
Dependency Security Copilot for AI Coding AgentsC8/10A plugin for LLM coding agents (Cursor, Claude Code, Copilot Workspace) that intercepts dependency operations, validates packages against threat intelligence, and prevents agents from blindly installing or upgrading to compromised versions.
Managed Dependency Mirror with Built-In QuarantineC7/10A hosted private registry proxy that mirrors npm, PyPI, and crates.io with an automatic 72-hour quarantine on all new publishes, behavioral analysis scanning, and instant rollback — so teams never pull a package version less than 3 days old.
AI Code Provenance and Supply Chain AuditingP6/10A platform that scans npm packages, PyPI modules, and other registries for accidentally leaked source maps, prompts, API keys, and internal business logic — alerting maintainers before attackers find them.
AI Authorship Detection for Code ContributionsC6/10A tool that integrates with GitHub/GitLab to probabilistically flag whether a pull request or commit was written by an AI agent, giving maintainers transparency without relying on self-disclosure.
