It focuses on: – persistent state and long-running executions – retries, branching and pause/resume – observability (logs, traces, cost) – human-in-the-loop approvals Launched on DevHunt: https://devhunt.org/tool/calljmp https://devhunt.org/tool/calljmp Happy to hear feedback or questions from the HN community.
