BlastRadar vs Respan Gateway (2026)
A side-by-side comparison of BlastRadar and Respan Gateway on pricing, features, and fit, so you can decide which is right for you.
Quick answer
BlastRadar and Respan Gateway are both strong choices, but they fit different needs. Choose BlastRadar if you mainly need assessing the risk of refactoring legacy code before making changes — its edge is reduces regression risk by surfacing hidden dependencies before deployment. Choose Respan Gateway if you need managing multi-provider llm traffic for production ai applications — its edge is combines routing, observability, and evals in a single platform reducing tool sprawl. BlastRadar starts at Contact for pricing; Respan Gateway starts at around $49/month based on usage volume.
Features compared
- Blast radius mapping for code changes across an entire codebase
- Dependency graph visualization showing upstream and downstream impact
- Automated change impact analysis to flag high-risk modifications
- Integration support for code review and CI/CD workflows
- Unified LLM routing across multiple AI providers with a single API endpoint
- Built-in observability including request tracing, latency monitoring, and logging
- Automated evaluations to benchmark and compare model outputs at scale
- Fallback and retry logic to handle provider outages and reduce downtime
Pros & cons
- Reduces regression risk by surfacing hidden dependencies before deployment
- Saves time compared to manually tracing impact across large codebases
- Helps engineering teams make more confident and informed code review decisions
- Pricing is not publicly available, making it harder to evaluate cost upfront
- May require setup and integration effort before delivering value in existing workflows
- Combines routing, observability, and evals in a single platform reducing tool sprawl
- Provider-agnostic design makes it easy to swap or mix LLM providers
- Saves engineering time by replacing custom middleware with ready-built infrastructure
- Relatively new platform so documentation and community resources are still maturing
- Advanced evaluation customization may require technical setup not suited for non-developers
