Kiro
AWS's spec-driven IDE that writes requirements before it writes code.
NOT REALLY
why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the dev tools job, so this one still earns its $19/mo.
- A named launch, not a vibe named, unlinked
- Free-form agents ship code fast but without a spec to check against. Anthropic, July 14, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? paid only
- 2 replacements listed, all paid.
- What the call is worth $228/yr
- $19/mo at the entry paid tier — $228 a year per seat.

The backstory
Kiro's argument against pure vibe coding is process: it turns a prompt into requirements, a design doc and tasks, then implements against them, with hooks that fire on file events. It is aimed at teams who found that unstructured agents produce a lot of code nobody can review.
