Sourcegraph Cody vs Vellum
Compare coding AI Tools
Sourcegraph Cody is an AI coding assistant built for complex codebases that integrates with major code hosts and editors, supports enterprise controls like data isolation and audit logs, and emphasizes code understanding at scale so teams can reuse prompts and standardize quality.
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.
Feature Tags Comparison
Key Features
- Code host integration: Works with common code hosts so Cody can reference real repository context instead of pasted snippets
- Major editor support: Designed to work with major editors so developers keep their existing workflow and tooling
- Enterprise security controls: Highlights data isolation zero retention no model training audit logs and controlled access for compliance
- Model choice: Mentions access to latest-gen LLMs that do not retain data or train on your code per the product page
- Prompt reuse governance: Encourages sharing and reusing prompts to automate tasks and promote best practices across teams
- Scale for large codebases: Designed to handle large repositories and large files so context stays usable at enterprise scale
- 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
- Large repo onboarding: Help engineers understand unfamiliar repositories faster by asking questions grounded in codebase context
- Refactor planning: Draft refactor approaches and check impacts across multiple modules with prompts guided by repository structure
- Code review support: Summarize changes and suggest review checklists that align to internal standards and common pitfalls
- Documentation drafting: Produce initial docs and READMEs from code context then enforce human review for accuracy and tone
- Migration assistance: Generate migration steps and helper code while tracking patterns across repositories and services
- Test creation: Draft unit tests and edge cases grounded in existing conventions then validate with CI and reviewers
- 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
