Pricing
FreeAider itself is completely free and open source under the Apache 2.0 license, with no subscription, tiers, or usage limits imposed by the project. Costs come entirely from the LLM provider a developer chooses to connect: for example, Anthropic, OpenAI, or DeepSeek API usage is billed directly by that provider at its own per-token rates, or developers can run local models through Ollama at no cost at all. Because there is no Aider-specific markup or platform fee, effective cost is determined by model choice and usage volume rather than by Aider itself.
FreemiumAmazon Q Developer offers a Free Tier at $0/month, including code suggestions in the IDE and CLI, reference tracking for open-source code, 50 agentic requests per month, up to 1,000 lines of Java code transformation, and limited security scanning. The Pro Tier costs $19 per user per month and adds enterprise access management with policies, the ability to customize Q Developer to a company's private codebase for better suggestions, IP indemnification, and significantly higher usage limits across all features. As of May 29, 2026, Q Developer Pro no longer receives access to the newest coding models (including Opus 4.6 and later), which are now exclusive to Kiro, AWS's successor product. New Q Developer account and subscription signups were blocked starting May 15, 2026; only existing subscriptions can add new seats going forward.

Aider Pros & Cons
Pros
- Completely free and open source, with no platform markup on top of LLM provider API costs
- Deep git-native workflow makes every AI change individually reviewable, diffable, and reversible
- Model-agnostic support for 100+ LLM providers, including local models, avoids vendor lock-in
- Efficient repo mapping keeps large codebases manageable without dumping entire files into context
- Transparent, actively maintained public leaderboard helps developers pick the best-performing model for real coding tasks
Cons
- Terminal-only interface has a learning curve for developers used to GUI-based tools like Cursor or Copilot
- No bundled AI access; users must bring their own API keys and manage separate billing with LLM providers
- Deliberately not a fully autonomous agent, staying one step behind tools like Devin that run unsupervised for longer stretches
- No official enterprise support tier or SLA, since the project is community-maintained open source
Amazon Q Developer Pros & Cons
Pros
- Free tier includes genuinely useful code transformation and 50 agentic requests per month
- Deep, native AWS integration lets developers query live account resources directly from chat
- Automated Java and .NET version upgrades can save enterprise teams months of manual migration work
- Pro tier's flat $19/user/month price includes IP indemnification, competitive against similar enterprise tools
- AWS Console, Docs, and Slack/Teams integrations remain fully supported and unaffected by the IDE sunset
Cons
- AWS is sunsetting the product: new signups have been blocked since May 15, 2026, and the IDE plugins reach full end-of-support on April 30, 2027
- Latest coding models (including Opus 4.7 and newer) are exclusive to Kiro, AWS's replacement product, not available on Q Developer Pro
- Deepest value is tied to AWS-specific workflows; less compelling for teams not building on AWS
- No JetBrains-native experience going forward, since new investment is focused on Kiro
- Existing users face a forced migration to Kiro or a competitor within the next several months
