driftless vs Kiro
Kiro is AWS's agentic IDE built around spec-driven development. driftless is the delivery platform built around the whole cycle: paired PRDs and tech specs, spec gates the platform enforces, and persistent agents that ship the work. Every competitor fact on this page was verified against kiro.dev on September 24, 2026.
Feature comparison
Kiro turns prompts into executable specs and checks them in the editor. driftless runs the same discipline as platform workflow: shaping, gating, shipping, and verification with bidirectional traceability.
| Capability | driftless | Kiro |
|---|---|---|
| Spec artifacts | Paired PRD and tech spec with bidirectional section-to-task traceability | Requirements, architectural designs, and sequenced task lists generated from prompts |
| Requirements checks | Spec gates run structural and semantic validation on every task | Automated reasoning checks requirements for contradictions and gaps before code is written |
| Gate enforcement | Enforced by the platform workflow: a failed gate stops the work in place | Checks run as analysis inside the IDE |
| Requirements shaping | BA Agent converts conviction into structured, testable, sequenced work | Specs are generated from prompts in the IDE |
| Agent execution | Persistent BA and coding agents orchestrated across the delivery cycle | Parallel agents in Kiro IDE, CLI, web, and cloud sessions |
| Verification | Automated acceptance-criteria validation in the Verify phase | Property-based tests assert rules that must hold across all inputs |
| Spec-to-task traceability | Bidirectional: every requirement traces to a task, every task to a requirement | Not documented on kiro.dev as of September 24, 2026 |
Pricing comparison
driftless prices per seat with no usage metering on the platform. Kiro prices per user with a monthly credit allowance, and model choice changes how fast credits burn.
| Pricing | driftless | Kiro |
|---|---|---|
| Pricing model | Per seat, flat monthly price | Per user, credit-metered |
| Free tier | $0: 1 user, 2 agents (BA + Coding), BYOK inference | $0: 50 credits, open-weight models and Claude Sonnet 4.5 |
| Entry paid tier | Pro: $100/seat/mo for the first 100 seats, $70/seat after | Pro: $20/user/mo with 1,000 credits |
| Higher tiers | Enterprise: custom, per seat, fully managed | Pro+ $40 (2,000 credits), Pro Max $100 (5,000), Power $200 (10,000) per user/mo |
| Overage and limits | BYOK lets inference run on your provider keys | Add-on credits $0.04 each; unused monthly credits do not roll over |
| Model cost | Billed by your provider under BYOK | Credit multipliers per model: Claude Sonnet 5 costs 1.3x the credits of Auto |
| Teams | Org-scoped agents; SSO and SCIM at the Enterprise tier | Each developer needs their own subscription; plans cover teams up to 500, with Kiro for enterprise above that |
FAQ
- How is driftless different from Kiro? Kiro is an agentic IDE: it turns prompts into requirements, designs, and sequenced tasks, checks requirements for contradictions and gaps with automated reasoning, and implements with parallel agents. driftless is a delivery platform: a BA agent shapes paired PRDs and tech specs, spec gates run as part of the platform workflow, and persistent agents execute tasks with automated acceptance-criteria validation. Choose driftless when you want the delivery cycle itself managed and enforced. Choose Kiro when the work you need is inside an editor.
- How does pricing differ between driftless and Kiro? driftless Pro is $100 per seat per month for the first 100 seats and $70 per seat after, with no credit metering; BYOK lets inference run on your provider keys. Kiro prices per user by credits: Pro is $20 per user per month with 1,000 credits, higher tiers run to Power at $200 per user per month with 10,000 credits, add-on credits cost $0.04 each, and unused monthly credits do not roll over. Model choice changes the rate: Claude Sonnet 5 consumes 1.3x the credits of Auto.
- Do Kiro's requirement checks enforce spec gates? Kiro checks your requirements for contradictions and gaps using automated reasoning before code is written. Those checks are analysis inside the IDE. driftless spec gates are enforced by the platform workflow, so a failed gate stops the work in place.
