Kiro vs GitHub Copilot (AI Code Editors & IDEs). Agent test scores: Kiro 9.7/10, GitHub Copilot 8/10. Kiro scored 1.7 higher overall in our separate rubric v0.1 tests (editions and tasks can differ — see Edition tested and the notes below). Pricing: Kiro — Free $0 (50 credits/mo); Pro $20/user/mo (1,000 credits); Pro+ $40 (2,000); Pro Max $100 (5,000); Power $200 (10,000); add-on credits $0.04 each; GitHub Copilot — Free $0; Pro $10/mo (1,500 GitHub AI Credits/mo incl. flex); Pro+ $39/mo (7,000); Max $100/mo (20,000); Business $19/seat; Enterprise $39/seat. These scores are not a head-to-head. Kiro 9.7 is three Free CLI T3 bug-fix runs on 2026-11-02 (kiro-cli, AWS Builder ID, Auto, self-ran node --test). GitHub Copilot 8.0 is one 2026-10-16 VS Code desktop run on Copilot Free that built a T1 todo app after the first chat failed three times.

What our tests found
Kiro
Three Free CLI T3 runs on 2026-11-02: each fixed the seeded cart.js discount bug so node --test passed 4/4 in 17–18s, leaving cart.test.js untouched and self-running the tests. Used about 0.80 of 50 monthly Free credits total ($0 spent) after Builder ID device-flow login; no API key.Free CLI / AWS Builder ID
- 3/3 Free CLI T3 runs fixed the bug in 17–18s with 4/4 tests passing
- Agent edited cart.js and ran node --test itself
- Used only about 0.80 of 50 monthly Free credits for three runs ($0)
- Free Builder ID session supports headless chat without an API key
- Free is 50 credits/mo and excludes Claude Opus, Sonnet 5.5, and GPT-5.6
- Official API keys / documented headless KIRO_API_KEY path need Pro or higher
- First login still needs interactive browser or device flow
- Headless Free runs need --trust-all-tools and --trust-workspace
Who it’s for: Developers who want a spec-driven agentic IDE/CLI from AWS, with a usable free tier for small tasks — and paid tiers that put several flagship models on one credit pool.
GitHub Copilot
Our first chat (Auto routed to GPT-5 mini) failed 3 times with 'Sorry, no response was returned'. A new chat in Copilot mode, where Auto picked gpt-6-luna, built the T1 todo app in 1m50s over 14 steps and tested it itself with Playwright. We verified it in headless Chrome: add, complete, delete, filters, reload persistence and a 375px mobile layout all passed, and the only console error was a missing favicon. Single run.desktop app, free plan
- Every T1 check passed in our own headless browser test, including mobile
- Tested its own work with Playwright in VS Code's built-in browser
- Built into VS Code; Copilot Free needs no payment
- Our build used 0% of the free monthly credits
- The first chat failed 3 times with 'Sorry, no response was returned' and needed a restart
- Needed two approvals to open a browser page and run Playwright
- Free plan is limited to 2,000 completions a month, a small AI Credits allowance and Auto model only
Who it’s for: Developers already in VS Code and GitHub who want a built-in agent with a free starter tier.
Verdict
Rubric v0.1, separate sessions, different tasks and editions. Do not read 9.7 versus 8.0 as one paired test. Choose Kiro for the tested Free CLI bug-fix path: three 2026-11-02 T3 runs on kiro-cli with AWS Builder ID and Auto, about 17–18s each, with the agent running node --test, about 0.80 credits for the three runs. Choose GitHub Copilot for the tested VS Code Free path: one 2026-10-16 T1 todo build on Linux (Auto routed to gpt-6-luna) that passed our checks after the first chat failed three times and needed a new chat. Copilot is a desktop editor test; Kiro’s published 9.7 is the CLI bug-fix edition, not that earlier IDE todo.
