Open-Source AI vs SaaS: What I Saved by Self-Hosting
July 10, 2026 · 12 min read
The Status Quo
Before switching to open-source, I was paying for multiple AI subscriptions. Here's what a typical month looked like:
- ChatGPT Pro — $200/month (unlimited GPT-4, DALL-E, advanced voice)
- Claude Pro — $20/month (for long-form writing and analysis)
- GitHub Copilot — $10/month (AI coding assistant)
- Midjourney — $30/month (image generation)
- Various API credits — ~$50/month (OpenAI, Anthropic, Replicate)
Total: ~$310/month
The Open-Source Alternative
By self-hosting with 9Router and free AI providers, here's what I saved:
| SaaS | Cost | Free Alternative |
|---|---|---|
| ChatGPT Pro | $200 | Groq Llama 3.3 70B (free tier) |
| Claude Pro | $20 | Gemini 2.5 Pro (free tier via API) |
| GitHub Copilot | $10 | GitHub Copilot Free tier |
| Midjourney | $30 | Cloudflare Workers AI (Free: 10k req/day) |
| API credits | $50 | OpenRouter free models + free tier APIs |
How It Works
The key is 9Router — an open-source AI provider router that gives you one API endpoint to access 18+ providers. Many of them offer generous free tiers:
- Groq — Free Llama 3.3 70B inference (fast)
- Cloudflare AI — 10,000 requests/day free (Qwen, Llama)
- GitHub Copilot — Free tier for VS Code
- Gemini API — Free tier with rate limits
- OpenRouter — Free models with limited requests
My Monthly Savings
After switching to self-hosted open-source:
- AI subscriptions: $0/month (all free tiers + open-source)
- Hosting: $6/month on a cheap VPS (optional, you can run on Android)
- Domain: ~$10/year (zes.codes via Namecheap)
- Total: ~$6/month + domain
Savings: ~$300/month — money that stays in my pocket.
The Trade-Offs
Self-hosting isn't for everyone. Here's what you give up:
- Setup time — Takes a few hours to configure everything
- Technical knowledge — Basic terminal comfort required
- Downtime — If your server goes down, so does your AI
- Model consistency — Free tiers have rate limits and can change
But if you're comfortable with a terminal and want to save hundreds per month, it's absolutely worth it.
Get Started
