20 Free AI Coding Tools: A Zero-Cost Starter Guide

On July 16, X user TheOyinbooke posted a multi-part thread compiling a "$0 to start an AI project" list of free AI coding tools, going through the free plans, trial quotas, usage limits and hidden terms of about 20 mainstream tools. The point is less about cataloguing products than helping newcomers judge which tools suit idea validation, which suit daily code completion, and which lean toward specific platforms or workflows.

Covered Tools and Quotas

The tools mentioned include Amazon Q Developer, Google AI Studio, the Google Antigravity CLI and Antigravity IDE, Windsurf Free, Cursor Hobby, GitHub Copilot Free and Grok Build. Amazon Q Developer offers 50 agentic requests per month across IDE and CLI, which the author sees as more AWS-oriented. GitHub Copilot Free provides 2,000 code completions and 50 Chat or Agent requests per month, supports Copilot CLI and multiple models, and requires no credit card; Windsurf Free has limited Agent calls but its Tab completion and inline capabilities remain usable.

The Author's Usage Advice

TheOyinbooke's core takeaway is that starting AI development at zero cost is feasible, provided you budget carefully against each tool's quota. He suggests using free allowances first for small tasks and validating ideas rather than having tools generate a full app right away, and dividing work by tool type — reserving completion quota for routine coding and the scarcer Chat or Agent requests for harder problems. On evaluation, he calls Grok Build the strongest coding agent he has tried.
