Cognition's autonomous software engineer that ships real pull requests
Devin plans, writes code, runs tests, and opens pull requests across complex, multi-repository codebases without waiting for line-by-line approval.
Devin provisions Windows, Mac, and Linux VMs, builds and runs the project, and tests in a real browser - even recording itself using the feature it built.
Mention @Devin in a thread to delegate a fix, or connect CI, PagerDuty, and issue trackers so it reacts to failures and alerts automatically.
Delegate a large task and Devin splits it across parallel cloud agents that keep working after you close your laptop, then reports back.
A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.
Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.
Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.

SpecialistA general autonomous agent platform executing multi-step goals and browsers, suitable for broader web and coding workflows.

Offers powerful parallel AI coding agents across an IDE and CLI, but lacks dedicated AWS ecosystem integrations.
#3
Builds and deploys full-stack apps instantly in the cloud, but lacks Kiro's local spec-driven engineering verification.

Free / Open-sourceWrite code with precision, hand bigger jobs to agents, and keep working from anywhere

Reads entire codebases to execute multi-file tasks as an IDE plugin, but offers less structured spec management.

SpecialistThe coding agent that learns your coding taste
Free / Open-sourceRuns multiple CLI coding agents in parallel using isolated Git worktrees, but requires manual setup over managed IDEs.
Delivers a fast AI-powered IDE environment for full projects, but lacks Kiro's strict architectural spec verification.

Focuses on enterprise multi-agent SDLC orchestration and deep context, but lacks Kiro's specific AWS backing and specs.
