Hopper, from YC S24 startup Hypercubic, is the first agentic development environment purpose-built for mainframe systems. It lets AI agents navigate TN3270 terminals autonomously, write and submit JCL jobs, monitor JES output, debug failed jobs by analyzing spool data, query VSAM datasets, compile and run COBOL code, and manage CICS transactions—all via natural language prompts. Tasks that traditionally took mainframe specialists hours of manual TN3270 navigation can now be expressed as a single instruction. The technical challenge here is real: mainframes don't have nice REST APIs or modern dev tooling. They run on green-screen terminal protocols from the 1970s, and the humans who know how to operate them are retiring faster than they can be replaced. Hopper essentially wraps the entire mainframe interaction surface in an agent-friendly interface, translating intent into the arcane sequences of keystrokes and JCL that mainframes actually require. The product is free for individual developers (all core features, macOS/Windows/Linux) with Enterprise pricing for SSO, on-prem deployment, and SOC 2 reports. Hypercubic's team includes alumni from Cognition, Apple, and Windsurf. Given that mainframes still process an estimated $3 trillion in daily commerce and the COBOL developer shortage is acute, Hopper is targeting a genuinely underserved market with unusual urgency.

Latitude is an observability platform specifically tuned for Claude Code usage. It captures every turn an agent runs — the prompts, tool calls, bash output, files touched, system prompt, and the tool schemas Claude Code composes at runtime — then surfaces it as cost breakdowns per prompt, per session, and per workspace. The platform routes Claude Code traffic through Latitude's instrumentation layer, giving engineering teams real visibility into what their AI coding agent is actually doing versus what they expect it to do. Teams can trace expensive tool-call chains, spot runaway loops, identify which slash-commands are budget-efficient, and attribute costs to specific tasks or repos without wading through raw OpenTelemetry traces. In a world where Claude Code rate limits and API costs are a real engineering budget concern, Latitude fills a genuine observability gap. It launched on Product Hunt today with 150 votes and complements Claude Code's native OpenTelemetry support by adding a human-readable interface and cost attribution dashboard that raw traces simply don't give you.
Reviewer scorecard
“This solves a real crisis. I've watched financial institutions pay six-figure consultant fees for tasks that Hopper demos suggest could be automated in minutes. If it's reliable on diverse JCL and CICS environments, this is immediately commercial.”
“Been waiting for exactly this. The per-session token breakdown finally shows which commands are bankrupting my API budget and which are model-efficient. The system prompt inspector — showing what Claude Code actually sends as context — is worth the signup alone.”
“Mainframe environments at major banks are extraordinarily heterogeneous—custom RACF configurations, vendor-specific CICS extensions, and decades of undocumented JCL conventions. An agent that confidently submits the wrong job in a production batch environment could be catastrophic.”
“You can get 80% of this from Claude Code's built-in OpenTelemetry output piped into a free Grafana dashboard. Latitude is betting that most teams won't DIY it — that's a fair bet — but the freemium paywall likely arrives before you're convinced to hand over a credit card.”
“The $3 trillion in daily mainframe commerce has been a black box to AI modernization. Hopper is the Rosetta Stone moment—once there's an agent-friendly interface to legacy systems, every other AI tool in the stack becomes accessible to that infrastructure.”
“As AI coding agents become the primary way software gets built, observability for agent behaviour becomes as mission-critical as APM was for microservices. Latitude is staking out the right territory at the right moment — this category will be worth billions.”
“There's something poetic about AI agents handling COBOL—the language written by Grace Hopper, now managed by a tool named after her. For teams modernizing legacy fintech systems, this is the missing piece.”
“Knowing the exact cost of each creative brief I throw at Claude Code would change how I scope projects. Understanding where the token budget disappears makes it easier to write better prompts and structure tasks more efficiently.”
