Hopper vs Respan Gateway (2026)
A side-by-side comparison of Hopper and Respan Gateway on pricing, features, and fit, so you can decide which is right for you.
Quick answer
Hopper and Respan Gateway are both strong choices, but they fit different needs. Choose Hopper if you mainly need understanding and documenting undocumented cobol programs — its edge is first agentic ai environment purpose-built for cobol and mainframe development. 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. Hopper starts at Contact for pricing details; Respan Gateway starts at around $49/month based on usage volume.
Features compared
- Agentic AI reasoning over COBOL and mainframe codebases
- Automated code understanding, documentation generation, and refactoring suggestions
- Legacy-to-modern migration assistance with step-by-step guidance
- Integrated development environment tailored for mainframe 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
- First agentic AI environment purpose-built for COBOL and mainframe development
- Reduces dependency on scarce COBOL expertise within organizations
- Accelerates modernization projects without requiring a full system rewrite
- Highly niche focus limits utility for teams not working with mainframe or COBOL
- Pricing and enterprise availability details are not fully transparent publicly
- 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
