## agentcad

agentcad tackles a specific problem: AI agents write plausible-looking CAD scripts that produce bad geometry on the first try. Instead of leaving you to babysit the iteration loop, it gives the agent a tight feedback cycle so it converges on printable, valid geometry on its own. You install it with pip inside a Python 3.10–3.12 virtual environment, point your agent at it, and hand over a parametric part description.

The design decisions center on verification. Every run returns machine-readable metrics — dimensions, volume, face and edge counts, and an is_valid flag — alongside PNG renders from any angle. The agent reads both, spots its own errors, and revises before you ever see a broken part. A pre-execution validation layer catches problems before anything runs, an inspection mode produces a topology report for debugging, and version diffs track how a design evolved over iterations.

Integration is deliberately lightweight. Scripts need no boilerplate imports because build123d primitives, show_object, and agentcad edit helpers are pre-injected, so `box = Box(10, 20, 5)` followed by `show_object(box)` just works. Adding it to `.mcp.json` makes it available in Claude Code, Cursor, or Windsurf, and it can run through uvx without a prior install. `agentcad init` also writes a Claude Code skill and an AGENTS.md block into the project so the agent knows the workflow in later sessions. Examples on the site include a 234-part 1903 Wright Flyer reconstruction and single-prompt parts such as a phone stand, a chess rook, and a filleted electronics enclosure — each reporting valid geometry, face and edge counts, and volume.

**Pricing & Plans:** Free and open source. agentcad is Apache-2.0 licensed, installs via pip or uvx, requires no signup, and runs entirely on your own machine.

- **Verified geometry feedback loop:** Every run returns dimensions, volume, face/edge counts, and an is_valid flag plus PNG renders so the agent can iterate until the part is genuinely printable.
- **build123d-native, CadQuery-compatible:** Scripts are written with the build123d API and pre-injected primitives, while CadQuery-compatible workflows are supported for existing projects.
- **Multi-format export:** Produce versioned STEP files for CAD interchange and STL, GLB, or OBJ for 3D printing and web viewers.
- **Validation, inspection, and diffing:** Pre-execution checks catch errors before running, a topology report helps debug geometry issues, and version diffs track design iteration.
- **Zero-boilerplate agent setup:** Add to .mcp.json for Claude Code, Cursor, or Windsurf, run via uvx without installing, and let agentcad init write a skill plus AGENTS.md into the project.

**Strengths:** Free and open source under Apache-2.0 with no signup required; Returns metrics and renders so agents catch bad geometry before you do; Runs locally with a small, zero-boilerplate scripting surface; Works with Claude Code, Cursor, Windsurf, and any MCP-compatible agent via uvx

**Limitations:** Requires Python 3.10–3.12 and comfort with script-based parametric modeling; Best results depend on an agent that can read metrics and iterate; It complements rather than replaces a full GUI CAD application for manual edits

## Replit

Replit began as one of the most popular browser-based coding environments and has evolved into an AI-first app and website builder. You describe what you want to build, and Replit's agent plans the work, writes production-ready code across the stack, iterates on feedback, and can publish the running app for you. Because everything happens in the cloud, there is no toolchain to install and no local environment to maintain.

The platform pairs the agent with the infrastructure a real product needs: authentication, a managed database, hosting, monitoring and more than a hundred integrations such as OpenAI, Stripe and Google Workspace. Recent releases added intelligent model routing that cuts the average cost of complex builds, an infinite canvas for visual design iteration and multi-user collaboration features aimed at teams.

Replit suits a very wide audience. Founders use it to go from idea to landing page or prototype in an afternoon, product managers build interactive demos instead of static specs, designers move straight from concept to functioning UI, and engineering teams use it to spin up internal tools quickly. A generous free mode lets people create without token costs, while paid plans unlock more powerful models, more storage and commercial usage.

**Pricing & Plans:** There is a free mode with limited chat hours and projects. Replit Core is about $20/month (about $18/month billed annually), and Replit Pro is roughly $90–100/month billed annually for commercial work. Enterprise plans add SSO/SAML, SOC 2 controls and admin features.

- **Agentic app generation:** Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
- **Built-in full-stack infrastructure:** Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
- **Free mode for experimenting:** A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
- **100+ integrations:** Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
- **Team and enterprise controls:** Multi-user collaboration, SSO/SAML, SOC 2 alignment and admin controls support professional and regulated use.

**Strengths:** No local setup; everything runs and deploys in the browser; Agent handles full-stack code, infrastructure and publishing; Free mode makes experimentation accessible; Strong collaboration, integrations and enterprise security controls

**Limitations:** Complex or highly custom architectures may still need manual engineering; Agentic build costs can rise quickly on heavier projects; Less control over low-level infrastructure than managing your own stack
