Reviewer scorecard
“The per-request pricing model is perfect for side projects — you literally pay nothing until you have traffic. Redis commands at $0.2/100K is incredibly cheap.”
“150ms cold starts for sandboxed code execution. Essential for AI agents that need to run untrusted code safely.”
“At high scale, per-request pricing can get expensive vs a fixed Redis instance. Know your traffic patterns. For most indie hackers and startups, it's a no-brainer.”
“AI agents running code need sandboxing. E2B's micro-VMs are purpose-built for this use case.”
“Upstash is doing for Redis what Neon did for Postgres — making it serverless-native. The QStash message queue is an underrated piece of the puzzle.”
“Safe code execution for AI agents is critical infrastructure. E2B is building the sandbox layer that every agent needs.”
