Tabnine vs Vellum
Compare coding AI Tools
Tabnine is an AI development platform with code completions, IDE chat, and workflow agents, designed for organizations that want privacy controls, flexible deployment options including SaaS, VPC, on premises and air gapped, and governance for safe adoption.
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
- AI code completions: Generate single line and multi line completions to accelerate implementation in the IDE
- IDE chat support: Use AI chat inside the IDE to assist planning debugging and refactoring across the SDLC
- Workflow agents: Use agents for test cases Jira implementation and code review to automate repeatable tasks
- Deployment options: Deploy as SaaS VPC on premises or fully air gapped based on security requirements
- Zero code retention: Claims zero code retention with privacy controls to protect proprietary repositories
- SSO and access control: Support SSO integration for private deployments and easier enterprise administration
- 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
- Feature implementation: Use completions to ship routine features faster while keeping human review in code review
- Unit test creation: Generate test scaffolds and cases to improve coverage and reduce repetitive test writing
- Jira to code flow: Turn ticket context into implementation steps and code changes with an agent workflow
- Code review support: Summarize diffs and propose fixes so reviewers focus on logic and risk not boilerplate
- Secure environments: Run AI assistance in VPC on premises or air gapped networks with controlled access
- Legacy modernization: Use IDE chat to refactor legacy modules while following internal standards and patterns
- 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
