Pros & cons
Mistral Vibe (Remote Agents) + Mistral Medium 3.5
Pros: Async parallel coding agents with teleportable session state; broad ecosystem integrations (GitHub/Linear/Jira/Sentry); SWE-Bench-leading model; weights open; EU-jurisdiction stack.
Cons: Vibe service closed; SWE-Bench claim is vendor self-report; no third-party reproduction yet; pricing tied to Pro/Team/Enterprise tiers; opaque memory eviction policy.
Replit Agent
Pros: Built into the Replit IDE so memory + execution + deployment are one product — agent memory is grounded in actual workspace state.
Cons: Tied to Replit's hosted environment; not usable for projects living in a normal local repo.
