Standout Differences

Deepest AWS ecosystem integration

Amazon Q Developer is unique among the three in offering application transformation for porting .NET applications and upgrading Java versions, plus native integration with the AWS Management Console.

Amazon Q Developer

Most generous free tier, but a confusing brand history

Codeium offers unlimited basic autocomplete for free across 70+ languages, but the product has been renamed twice in under two years, from Codeium to Windsurf to Devin Desktop under new owner Cognition AI, which can make it harder to evaluate consistently across reviews.

Codeium

Built for regulated, privacy-sensitive environments

Tabnine is the only one of the three documented to offer zero data retention plus SaaS, virtual private cloud, on-premises, and fully air-gapped deployment options, at the cost of dropping its free individual tier in 2025.

Tabnine

All three now ship agentic, not just autocomplete, capabilities

Amazon Q Developer's agentic tasks, Codeium's Devin Local agent mode, and Tabnine's Agentic Platform tier all move beyond simple code completion into autonomous multi-step coding work.

Amazon Q Developer, Codeium, Tabnine

Open agent interoperability

Codeium supports the open Agent Client Protocol, letting third-party agents run inside its editor, while Tabnine connects to external tools and data sources through Model Context Protocol integrations.

Pros & Cons

Amazon Q Developer

Pros

  • Free tier available with no cost to start
  • Deep integration with AWS services and the AWS Management Console
  • Agentic capabilities go beyond autocomplete into test generation and code review
  • Supports legacy application modernization (.NET and Java transformation)

Cons

  • Deepest value is realized within the AWS ecosystem, less compelling for non-AWS shops
  • Free tier usage limits (50 agentic interactions/month) are relatively low for heavy users
  • Per-user Pro pricing can add up for larger engineering teams

Codeium

Pros

  • Generous free tier with unlimited basic autocomplete and support for 70+ languages
  • Backward-compatible rebrand meant existing Windsurf/Codeium users kept accounts, plans, and settings automatically
  • Open Agent Client Protocol support avoids locking users into a single vendor's agent
  • Backed by Cognition AI's broader Devin agent ecosystem and ongoing investment

Cons

  • Two rebrands in under two years (Codeium to Windsurf to Devin Desktop) make the product harder to track and compare across reviews
  • Cascade, the previous built-in agent, was fully retired on July 1, 2026, requiring users to adapt to Devin Local
  • Pro plan pricing has increased over time (from $15 to $20/month as of mid-2026)
  • Full agentic feature set requires the standalone desktop app rather than the lightweight plugin

Tabnine

Pros

  • Strong focus on code privacy with zero data retention
  • Flexible deployment including fully air-gapped on-premises installs
  • IP-indemnified suggestions trained on permissively licensed code
  • Broad IDE support across major development environments
  • Agentic Platform adds multi-step autonomous coding workflows

Cons

  • No free or low-cost individual plan as of 2026
  • Both core plans require annual billing commitments
  • LLM token costs can apply separately on top of subscription fees
  • Smaller review volume on sites like G2 compared to larger competitors
  • Higher price point than some general-purpose AI coding assistants

Frequently Asked Questions

Which of these three has a free plan?

Amazon Q Developer and Codeium both offer free tiers, Amazon Q Developer with 50 agentic chat interactions per month and Codeium with unlimited basic autocomplete. Tabnine dropped its free individual tier in 2025 and now starts at $39/user/month.

Which is the best choice if my team is deep in the AWS ecosystem?

Amazon Q Developer, since it integrates directly with the AWS Management Console and offers application transformation features like .NET porting and Java version upgrades that the other two do not document.

Can I run any of these fully offline or air-gapped?

Only Tabnine documents on-premises and fully air-gapped deployment options, aimed at regulated industries like finance, healthcare, and government.

Which tool lets me run other vendors' coding agents inside it?

Codeium, through its support for the open Agent Client Protocol, which lets third-party agents such as Codex, Claude Agent, and Gemini CLI run inside its editor rather than locking users to one vendor's agent.

Is Codeium still called Codeium?

Not exactly. The product launched as Codeium in 2021, was rebranded to Windsurf in 2024, and was renamed again to Devin Desktop after Cognition AI acquired it in December 2025. Existing accounts, plans, and settings carried over automatically through each rename.

Which is the most expensive on a per-seat basis?

Among listed per-seat team pricing, Tabnine's Agentic Platform tier at $59/user/month is the highest base per-seat price, compared to Amazon Q Developer's Pro tier at $19/user/month and Codeium's Teams plan at $80/month plus $40 per seat.
