The short list (Sep 2026)
- Best under-$20 default: GitHub Copilot (multi-IDE + GitHub-native)
- Best if you live in VS Code: Cursor free/entry (stay inside limits)
- Best free-ish starter: Gemini Code Assist (confirm current free tier)
- Best open / BYO-key: Continue.dev (+ your own model budget)
- Graduate off this list: Cursor Pro + Claude Code — see full coding assistants guide
What “under $20” still means
An indie budget is real. ~$20/mo is where “is this worth it?” becomes “which one?” We’re holding tools that can run today on Mac/Linux/Windows and plug into VS Code and/or JetBrains without an enterprise contract. We’re not pretending Claude Code or heavy agent seats usually fit this band — those belong on the full guide.
Capability comparison
| Tool | ~Budget fit | Best at | Watch-outs |
|---|---|---|---|
| GitHub Copilot | Pro ~$10/mo (Pro+ $39 / Max $100 graduate) | Any-IDE autocomplete + GitHub agents | AI Credits do not roll over; Pro+ / Max exceed $20 |
| Cursor (free/entry) | Free tier / entry plans | Composer + tab in VS Code fork | Limits; Pro may exceed $20 |
| Gemini Code Assist | Free / cheap individual | Starter assist in supported IDEs | Confirm live free quotas |
| Continue.dev | Free client; you pay models | Local/BYO-key control | Model spend can blow the $20 cap |
| Codeium / Windsurf free lanes | Free tiers vary | Autocomplete experiments | Product names and limits churn — recheck |
The verdicts
GitHub Copilot — safest under-$20 default
Still the pick when you bounce across IDEs or your work already lives on GitHub. Use it when you want the least-friction “just help me code” seat under the budget line. As of September 2026, stay on Pro ($10/mo) for this lane — Pro+ ($39) and Max ($100) are graduate seats once AI Credits / premium models become the bottleneck. Copilot Pro includes 1,500 GitHub AI Credits a month (1,000 base + 500 flex), and unused credits do not carry over to the next month (sources: docs.github.com Copilot plans and usage-based billing for individuals).
Cursor free/entry — best VS Code–native feel under the cap
If most of your day is VS Code-shaped multi-file work, Cursor’s free/entry experience beats Copilot’s plugin feel — until you hit limits. Don’t assume Pro still counts as “under $20”; check the current plan page.
Gemini Code Assist — best free-ish on-ramp
Start here if you’re not ready to pay. Graduate when autocomplete quality or agent depth becomes the bottleneck.
Continue.dev — best if you already have API keys
Great control; easy to accidentally spend more than $20 on model tokens. Budget the keys, not just the IDE plugin.
What I would actually pick by stack
- Multi-IDE / GitHub shop: Copilot
- VS Code daily driver, tight budget: Cursor free/entry → Pro when limits hurt
- $0 month: Gemini Code Assist or Continue + a cheap/free model
- Ready to spend for agents: leave this page → Cursor + Claude Code stack
Buyer’s framework
- Count IDEs you actually use weekly.
- If it’s “mostly VS Code,” try Cursor free before paying Copilot.
- If it’s “many IDEs / GitHub Enterprise gravity,” pay Copilot.
- If you need terminal repo agents, you’re graduating — budget Claude Code separately.
FAQ
Is GPT-4 the thing to buy?
No — GPT-4 is a model name, not a coding-assistant product. You’re buying an assistant product (Copilot, Cursor, Gemini…) that may route to current frontier models behind the scenes.
Should indie shops skip straight to Claude Code?
Only if repo-level agents are the daily job and you can fund the plan. Otherwise exhaust the under-$20 lane first.

Once the under-$20 assistant is paying for itself, the next quality unlock is usually review — not another autocomplete seat. Compare the best AI code review tools 2026 when PR comments, security scans, or style gates start eating more time than writing the first draft.
