| **16-core machine** | $1.44/hour | CI/CD, large builds |
| **Storage** | $0.07/GB/month | Charged while stopped |

### Free Tier (Personal Accounts)

- 120 core hours/month (free)
- 15 GB storage (free)
- Does **not** apply to organization accounts

### 10 Developer Cost Model

#### Scenario 1: Conservative (4 hours/day, 2-core)

```
Compute: 10 devs × 80 hrs/month × $0.18/hr = $144/month
Storage: 10 devs × 20 GB × $0.07/GB = $14/month
Total: $158/month
```

#### Scenario 2: Moderate (6 hours/day, 4-core) ⭐ **Recommended**

```
Compute: 10 devs × 120 hrs/month × $0.36/hr = $432/month
Storage: 10 devs × 32 GB × $0.07/GB = $22.40/month
Total: $454.40/month baseline

With prebuilds (reduce active time by 30%):
Compute: 10 × 84 hrs × $0.36 = $302.40/month
Prebuild overhead: ~$50/month
Storage: $22.40/month
Total: ~$375/month
```

#### Scenario 3: Heavy (8 hours/day, 4-core)

```
Compute: 10 devs × 160 hrs/month × $0.36/hr = $576/month
Storage: 10 devs × 32 GB × $0.07/GB = $22.40/month
Total: $598.40/month baseline

With prebuilds:
Compute: 10 × 112 hrs × $0.36 = $403.20/month
Prebuild overhead: ~$80/month
Storage: $22.40/month
Total: ~$505/month
```

### Annual Costs

| Scenario | Monthly | Annual |
|----------|---------|--------|
| Conservative | $158 | $1,896 |
| Moderate (no prebuilds) | $454 | $5,448 |
| Moderate (with prebuilds) | $375 | $4,500 |
| Heavy (no prebuilds) | $598 | $7,176 |
| Heavy (with prebuilds) | $505 | $6,060 |

### Hidden Costs

1. **Storage accumulation:** Charged even when workspace is stopped
2. **Forgotten workspaces:** Old workspaces continue to accrue storage costs
3. **Large builds:** Building Docker images inside Codespaces uses compute time
4. **Port forwarding:** Free (no additional cost)

### Cost Optimization Tips

1. **Enable auto-delete:** Delete workspaces after 30 days of inactivity
2. **Use prebuilds:** Can reduce active compute time by 30-40%
3. **Stop when idle:** Set default timeout to 30 minutes
4. **Monitor usage:** Use GitHub billing dashboard regularly
5. **Right-size machines:** Use 2-core for light editing, 4-core for active development

2. **Credit exhaustion:** Full-stack development exhausts credits quickly
3. **No Docker Compose optimization:** Not designed for complex orchestration
4. **Storage costs:** Large databases and dependencies

**Verdict:** ❌ Not recommended for TracerTM (better alternatives at lower cost)

---

## StackBlitz & VS Code Web

**Not Applicable for TracerTM**

Both platforms cannot run the full TracerTM stack:
- StackBlitz: Frontend only (no Go, Python, PostgreSQL)
- VS Code Web: No runtime (editing only)

**Cost:** Free (but not suitable for full-stack development)

## Break-Even Analysis

### When Does Self-Hosted (DevPod) Make Sense?

**Break-even point:** When infrastructure costs < (managed platform costs - DevOps time costs)

For 10 developers:
- **Managed platform (Gitpod):** $650/month = $7,800/year
- **Self-hosted (DevPod):** $469/month infra + $1,000/month DevOps = $17,628/year

**Conclusion:** Self-hosted **not cost-effective** at 10 developers unless:
- DevOps time is free (already on payroll)
- Using Spot instances + automation (minimal management)
- Team size > 50 developers (economies of scale)

**Recommended threshold:** Self-hosted makes sense at **50+ developers**

```
50 developers × $65/month (Gitpod) = $3,250/month
vs.
50 developers × $47/month (DevPod) + $1,000 DevOps = $3,350/month

Still slightly more expensive, but gets better at scale.
```

---

## Recommendations by Team Size

### Small Team (1-5 developers)

**Best:** GitHub Codespaces (if GitHub-heavy) or Gitpod

- **Codespaces:** $200-300/month
- **Gitpod:** $175-325/month

**Winner:** Gitpod (lower cost, faster prebuilds)

### Medium Team (10-20 developers)

**Best:** Gitpod or GitHub Codespaces

- **Codespaces:** $600-1,200/month
- **Gitpod:** $500-1,300/month

**Winner:** Gitpod (better value, no storage costs when stopped)

### Large Team (50+ developers)

**Best:** DevPod (self-hosted) or Gitpod Enterprise

- **DevPod:** $2,000-3,000/month + DevOps
- **Gitpod:** $3,000-5,000/month (enterprise pricing)

**Winner:** DevPod with automation (economies of scale)

---

## Cost Optimization Best Practices

### 1. Use Prebuilds (30-40% savings)

Reduce active compute time by pre-installing dependencies:
- **Codespaces:** GitHub Actions prebuild workflow
- **Gitpod:** .gitpod.yml init tasks

**Savings:** $150-200/month (10 devs)

### 2. Set Idle Timeouts (20-30% savings)

Auto-stop workspaces after inactivity:
- **Recommended:** 30 minutes
- **Aggressive:** 15 minutes

**Savings:** $100-150/month (10 devs)

### 3. Delete Old Workspaces (Storage savings)

Delete workspaces after 30 days:
- **Codespaces:** $0.07/GB/month accumulates
- **Gitpod:** No storage cost when stopped (less critical)

**Savings:** $50-100/month (Codespaces only)

### 4. Right-Size Machines

Use smallest machine that works:
- **Editing:** 2-core ($0.18/hr Codespaces)
- **Development:** 4-core ($0.36/hr Codespaces)
- **Builds:** 8-core ($0.72/hr Codespaces)

**Savings:** $100-200/month (10 devs)

### 5. Monitor Usage

Track actual usage vs. budgeted:
- GitHub billing dashboard
- Gitpod usage analytics
- Set spending alerts

**Savings:** Catch runaway costs early

---

## ROI Calculation

### Cost vs. Value

**Cloud IDE Costs (Gitpod, 10 devs):** $650/month = $7,800/year

**Value Delivered:**

1. **Onboarding time savings:**
   - Traditional setup: 4-8 hours/developer
   - Cloud IDE: 5-15 minutes
   - Savings: 4-8 hrs × 10 devs × $100/hr = $4,000-8,000/year

2. **Environment consistency:**
   - Eliminates "works on my machine" issues
   - Reduces debugging time: ~2 hrs/week/dev
   - Savings: 2 hrs × 52 weeks × 10 devs × $100 = $104,000/year

3. **Collaboration efficiency:**
   - Live Share, preview URLs, real-time editing
   - Saves ~1 hr/week/dev in context switching
   - Savings: 1 hr × 52 weeks × 10 devs × $100 = $52,000/year

**Total Value:** $160,000-164,000/year

**Net ROI:** ($160,000 - $7,800) / $7,800 = **1,951% ROI**

**Conclusion:** Cloud IDEs pay for themselves in onboarding alone.
