## Overview

Comprehensive reference of free-tier SaaS, PaaS, and IaaS services for developers. Covers cloud providers, CI/CD, code quality, monitoring, auth, CMS, hosting, databases, email, CDN, testing, and security tools. Sourced from the free-for-dev list (https://github.com/ripienaar/free-for-dev).

## Capabilities

- Recommend free-tier cloud providers and compute options
- Compare CI/CD free plans across major platforms
- Suggest free code quality and monitoring tools
- Identify free auth, CMS, hosting, and database providers
- Evaluate free email, CDN, testing, and security services
- Match service selection to project requirements and scale

## When to Use

**Trigger phrases:**
- "free dev resources"
- "Starting a side project or MVP with zero budget"
- "Comparing free tiers before committing to a provider"
- "Recommending tools for bootstrapped startups"


- Starting a side project or MVP with zero budget
- Comparing free tiers before committing to a provider
- Recommending tools for bootstrapped startups
- Optimizing costs for hobby or educational projects
- Setting up dev/staging environments without paid plans
- Building a developer toolkit from scratch

## When NOT to Use

- Task is about deployment, not development (use deploy skills)
- Task is about code review, not writing (use review skills)
- You need to understand existing code first (use research skills)
- Task is about testing only (use test skills)
- Requirements are unclear (clarify first)
- Task is trivially simple (single line fix)


## Process

```python
# Example: TDD workflow
def test_user_creation():
    user = create_user(name="Alice", email="alice@example.com")
    assert user.name == "Alice"
    assert user.email == "alice@example.com"
    assert user.created_at is not None

def test_user_creation_invalid_email():
    with pytest.raises(ValidationError):
        create_user(name="Alice", email="invalid")
``` / Steps

1. **Identify requirements** -- What category of service is needed (compute, database, auth, etc.)?
2. **Check free tier limits** -- Verify request limits, storage caps, user limits, and duration (always-free vs. time-limited trial).
3. **Evaluate lock-in risk** -- Prefer services with easy migration paths and open standards.
4. **Consider scaling costs** -- What happens when the free tier is exceeded? Are paid plans reasonable?
5. **Verify current status** -- Free tiers change; confirm the service still offers what is documented.

## Verification

- [ ] Service is still offering a free tier (check URL)
- [ ] Free tier limits match the project's expected usage
- [ ] No hidden costs (bandwidth overages, per-seat charges)
- [ ] Migration path exists if the service is discontinued
- [ ] Terms of service allow the intended use case
- [ ] Service is not a time-limited trial when always-free is needed

## How to Use

1. Understand the requirement and existing codebase patterns
2. Design the solution with error handling and testability in mind
3. Implement incrementally with tests for each change
4. Verify against expected outcomes (manual and automated)
5. Document usage, edge cases, and integration points
6. Review with team before merging to shared branches

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "Tests slow me down" | Bugs slow you down 10x more. Tests are speed, not overhead. |
| "I will refactor later" | Technical debt compounds. Refactor as you go. |
| "It works on my machine" | If it is not in CI, it does not work. Ship proof, not claims. |
