Key Features
- 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
- 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
Use Cases
- 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
- 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
