Firebase provides real-time database, authentication, hosting, cloud functions, and analytics. The original BaaS platform. Still popular despite Supabase's rise.

E2B provides sandboxed cloud environments for AI-generated code execution. Micro-VMs that spin up in 150ms for safe code execution by AI agents.
Reviewer scorecard
“Authentication, Firestore, and Cloud Functions get you from zero to production fast. The free tier is generous.”
“150ms cold starts for sandboxed code execution. Essential for AI agents that need to run untrusted code safely.”
“Firestore's limitations become painful at scale. Supabase with Postgres is the modern alternative.”
“AI agents running code need sandboxing. E2B's micro-VMs are purpose-built for this use case.”
“Firebase defined BaaS but Supabase's open-source, Postgres-based approach is the future.”
“Safe code execution for AI agents is critical infrastructure. E2B is building the sandbox layer that every agent needs.”
