Amazon Q Developer vs Vellum
Compare coding AI Tools
Amazon Q Developer is AWS’s coding assistant that provides IDE chat, inline code suggestions, and security scanning, plus CLI autocompletions and console help, with a Free tier and a Pro tier that adds higher limits and advanced features for teams in AWS environments.
Vellum is an AI agent building platform that combines a prompt playground, evaluation tools, and hosted agent apps so teams can iterate on LLM workflows with debugging and knowledge base support, starting with a free tier and upgrading for more credits.

Key Features
- IDE chat assistant: Chat about code in supported IDEs to get explanations suggestions and guidance using project context
- Inline code suggestions: Receive code completions and generation while editing to speed implementation and reduce boilerplate
- Vulnerability scanning: Scan code for security issues inside the IDE to catch risky patterns earlier in the development lifecycle
- Code transformation agents: Perform automated upgrades and conversions that produce diffs you review before applying changes
- CLI autocompletions: Get command completion and AI chat guidance in the terminal for local workflows and Secure Shell sessions
- AWS console help: Open an Amazon Q panel in the console to ask questions and navigate AWS tasks with contextual responses
- Free and Pro plans: Pricing starts at $0 with 50 credits and Pro at $25 with 200 builder credits so solo builders can scale testing
- Prompt playground: Compare models side by side and iterate prompts systematically instead of relying on subjective testing
- Evaluations framework: Run repeatable quality tests at scale to detect regressions and track improvements across prompt versions
- Hosted agent apps: Share working agents with teammates through hosted apps for demos
- reviews
- and stakeholder feedback cycles
Use Cases
- Write AWS integrations: Ask for SDK usage examples and apply inline suggestions while building services that call AWS APIs
- Fix security issues: Use vulnerability scan findings to prioritize fixes and generate safer code patterns inside reviews
- Modernize Java apps: Run transformation workflows to upgrade language versions then review diffs before accepting changes
- Terminal efficiency: Translate intent into CLI commands with autocompletion support during local and remote development sessions
- Cloud troubleshooting: Use IDE chat to explain errors then validate by running tests and applying minimal code changes safely
- In-console guidance: Ask questions in the AWS console panel to locate services and understand configuration steps faster
- Agent prototyping: Build an agent by chatting with AI then refine logic with low code steps and controlled prompt versions
- Prompt iteration: Compare LLM outputs side by side and select prompts that improve accuracy and reduce unwanted variation
- Regression testing: Run evaluations on a saved dataset before release to catch quality drops after model or prompt changes
- RAG apps: Attach a knowledge base and test retrieval behavior with representative questions and strict document scope rules
- Stakeholder demos: Publish hosted agent apps so product and compliance reviewers can test behavior without local setup steps
- Model selection: Evaluate providers and self hosted options with the same tasks to choose the best cost and latency mix for production
