AI provider fallback chain (auto-retry on rate-limit / 5xx)	❌	✅
Git-branch rollback (every inject = its own branch)	❌	✅

Free tier (always free)

scan · audit · diff · cost · frameworks · providers · explain · license

Run scans on any project, any time, no key required. This is the acquisition loop — get a real production-readiness score before deciding if inject is worth paying for.

Paid tier (license key required)

inject · recipe apply · upgrade · sync · fix-wiring · install

export SHADOW_STACK_LICENSE_KEY=solo_xxxxxxx
shadow-stack inject ./myproject --only auth payments monitoring

Tiers: solo_* ($29/mo) · team_* ($99/mo) · ent_* ($499/mo) · lifetime_* ($149)

Framework support

Framework	Detect	Inject	Modules
FastAPI	✅	✅	All 16 Python modules
Django	✅	◑	auth, monitoring, security, tests, docker, deployment
Flask	✅	◑	auth, monitoring, security, tests, docker
Express	✅	✅	v5 NEW — node_auth/security/monitoring/tests/docker
NestJS	✅	✅	v5 NEW — same Node module pack
Next.js	✅	◑	v5 NEW — node_auth, node_monitoring, node_tests
Fastify	✅	○	Detection only
React/Vite	✅	◑	node_tests
Go (Gin)	○	○	Planned v6

The scanner is framework-aware: a Next.js project no longer gets false-positive "missing password hashing" warnings just because the FastAPI checker doesn't know JS.

---

Git-branch rollback

Every inject in a git repo creates a dedicated branch:

shadow-stack/inject-auth-monitoring-20260510-153022

Review the diff, then merge or rollback:

git checkout main && git merge --no-ff <branch>   # accept
git checkout main && git branch -D <branch>       # discard

shadow-stack rollback ./myproject --cleanup 14 cleans up branches older than 14 days.

---

AI provider fallback (v5 reliability fix)

Default chain: anthropic → openai → gemini → groq → deepseek → ollama

If your primary rate-limits halfway through a 12-module inject, v5 auto-retries on the next available provider. v4 used to fail the whole run.

Set SHADOW_STACK_AI_PROVIDER=openai to pin a specific primary; the chain still applies on failure.

GitHub Action

# .github/workflows/health-score.yml
on: [pull_request]
jobs:
  scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: shadowhunter89/shadow-stack/.github/actions/scan@v5
        with:
          fail-below: 60      # fail the PR if score drops below 60
          comment-on-pr: true # post score as a PR comment

What the comment looks like

On every pull request, the action posts a comment like this:

🟡 shadow-stack score: 62/100

Framework	fastapi
Missing modules	6
Critical security issues	2

Run shadow-stack inject locally to fix the gaps. Get a license to enable inject.

Score emoji is colour-coded:

• 🟢 80+ — production-ready
• 🟡 60-79 — has gaps, but shippable
• 🔴 < 60 — needs work before launch

What you'll see in the GitHub Actions tab

The action also writes a Job Summary visible in the run page:

## shadow-stack scan

| Metric | Value |
|--------|------:|
| Health Score | 62/100 |
| Framework | fastapi |
| Missing modules | 6 |
| Critical issues | 2 |

Outputs you can use in downstream steps

- uses: shadowhunter89/shadow-stack/.github/actions/scan@v5
  id: scan
- run: echo "Health = ${{ steps.scan.outputs.health-score }}"
- run: echo "Framework = ${{ steps.scan.outputs.framework }}"
