We maintain head-to-head comparisons for 11 AI coding tools, re-checking every price against the vendor's own page. This pair is the odd one out: as of today, neither Amazon Q Developer nor Tabnine can actually be bought by a new individual user.
Amazon Q Developer — AWS closed new Q Developer signups on 15 May 2026. Existing subscriptions can still add seats, but a developer starting today cannot sign up at all. Support ends 30 April 2027, and AWS points new users at Kiro instead. Vendor's own announcement.
Tabnine — Acquired by Tricentis on 30 July 2026. tabnine.com now redirects to Tricentis; there's no public pricing page and no self-serve signup. Existing customers keep support, but you can't start fresh. Vendor's own announcement.
Last published prices, for the record: Amazon Q Developer Pro was $19/user/month (existing subscriptions only). Tabnine's Code Assistant and Agentic tiers were $39 and $59/user/month before the acquisition closed.
What still sets them apart, for anyone grandfathered into either:
- Codebase context — Amazon Q works at workspace scope; Tabnine claims full-project context.
- Self-hosted / on-prem — Tabnine supports it, Amazon Q doesn't.
- Works alongside any editor — Amazon Q does; Tabnine's current positioning doesn't emphasize it.
Neither entry exists to sell you anything — we're not enrolled in an affiliate program for either tool, and most tools on this list don't run one.
