Start with the reason to change

You need a different hosted environment, repository workflow, or agent boundary and can assess the full application lifecycle instead of the first preview.

Alternative product fits

01

AI coding agent

Devin

A software-engineering agent operating in a controlled development environment fits the change set.

Verify: Repository and environment access, planning, tool actions, tests, security, review effort, and rollback.
02

AI coding editor

Cursor

An AI-oriented local editor better matches an existing repository workflow.

Verify: Context, model and agent mode, edit scope, command permissions, tests, security, and code ownership.
03

AI coding assistant

GitHub Copilot

GitHub and existing IDE continuity are material constraints.

Verify: Exact editor and repository surface, organization controls, agent permissions, tests, branch policy, and review.
04

AI coding assistant

Amazon Q Developer

AWS-facing development tasks or supported modernization workflows belong in the pilot.

Verify: IDE or command-line surface, identity, repository scope, changes, tests, deployment boundary, and controls.

Switching checklist

  1. Select representative repositories, change types, tests, and forbidden files before the pilot.
  2. Pin the editor, model or agent surface, permissions, and tool configuration for each run.
  3. Measure accepted changes, test pass rate, scope violations, security findings, and review time.
  4. Review repository access, telemetry, retention, and organization controls in current official documentation.
  5. Require human approval and a clean rollback for every evaluated change.

Latest releases

IndexNow proof-origin protocol fix

Production Bing validation exposed HTTP 500 at the external root proof because TLS termination was followed by an internal rewrite using the wrong protocol. This release corrects that rewrite boundary, but remains unverified until the external proof returns HTTP 200, the automatic submission runs, a later canary returns HTTP 200, and the idempotent rerun passes.

IndexNow root-proof request compatibility

After v4.3.3, the exact root-level {key}.txt proof returned HTTP 200, but a full request carrying keyLocation still returned HTTP 403; a minimal homepage request with the same production key and no keyLocation returned HTTP 202. This release omits that field, while the automatic full run and idempotent rerun remain deployment checks.

IndexNow key-proof compatibility

Changed IndexNow verification to the official root-level {key}.txt convention after the first production notification returned HTTP 403; revalidation remains pending, while the website, sitemaps, and Bing sitemap processing are unaffected.
