I built a VS Code extension that generates full production APIs from plain English - and v0.6 now includes deploy simulation + infra scanning

Hey all - solo dev here. I've been working on a VS Code extension called SwiftStack AI. It started as a plain-English -> API generator, but it's turning into more of a "developer intelligence" toolkit.

The core workflow:

Describe your schema -> pick a language/framework(FastAPI, Express, Spring, Gin, Rails, etc.) -> it generates models, routes, auth, tests, and Docker config.

The new stuff is what I'm most excited about:

• Zero-Downtime Deploy Simulator

Point it at your Dockerfiles, K8s manifests, Terraform, or CI/CD configs -> get a 0-100 safety score with ranked findings.

• Fix My Infra

Scans for missing healthchecks, hardcoded secrets, no-multi-stage builds, missing probes, insecure defaults. Streams corrected files.

• Performance Bottleneck Predictor

Detects N+1 queries, missing indexes, unbounded queries, sync I/O in hot paths.

• Explain This Error

Paste any stack trace -> get root cause, fix, and prevention steps.

• Architecture Evolution Advisor

Looks at codebase metrics and suggests what architectural move to make next.

Also includes: live health score in the status bar (exportable for CI), dependency vulnerability scanning, DB schema visualization, and a PR review agent.

83 installs in 4 days. Not huge, but I'm building in public and shipping fast.

If you try it, I'd love to know:

• What's useful?

• What's missing?

• What would make you keep it installed long-term?

You can find it by searching "SwiftStack AI" in the VS Code Marketplace.
