Most solo devs pay $80–200/mo for AI coding tools and use a fraction of it. This 5-minute audit shows you what each one actually costs for the way you work — and the $15–35/mo stack that does about 90% of the job.
Prices hand-verified against official pages, as of 2026-06-10 (US). No rankings — the right answer depends on how you code.
Free. Twice a month. We email you the moment a tool you use changes its price. One-click unsubscribe.
Open your AI tool's usage dashboard, read last month's actual usage (tokens / requests / hours), and compare it to your flat monthly plan. If a pay-as-you-go (metered) estimate would have cost less than your subscription, you're buying capacity you didn't use.
| Piece | Cost | Job |
|---|---|---|
| GitHub Copilot | $10/mo | always-on autocomplete |
| Cline / Continue (open source) | free | the agent / multi-file edits |
| Cheap model API (DeepSeek / Qwen) | ~$5–25 usage | powers the open agent |
≈ $15–35/mo instead of $120+ for light-to-moderate use. The frontier models still win the single hardest reasoning step — keep one, on metered.

| GitHub Copilot | Pro $10/mo · Pro+ $39/mo (usage-based credits live; new signups paused) |
