a2a cloud vs Modal for deploying AI agents
Modal is excellent serverless GPU and CPU compute — arguably the best raw infrastructure for running AI workloads. But it gives you compute, not an agent. a2a cloud deploys the whole agent app and proves what it did.
Where Modal is genuinely strong — and where a2a cloud is different.
Serverless GPU compute, done right
Modal nails the hard part of infrastructure: fast cold starts, fine-grained GPU autoscale, a clean Python-first deploy experience. If you need to run heavy model inference or batch compute, Modal is a genuinely great place to run it.
The whole agent app — plus proof
a2a cloud sits at the agent layer, not the compute layer. One deploy ships managed Postgres, MCP, a frontend, and an API. Authenticated Agent API calls and public `/invoke` or standard MCP `tools/call` executions receive signed receipts under scoped grants.
a2a cloud vs Modal, dimension by dimension.
A fair comparison. Both columns are accurate as we understand the products today — the difference is what the runtime owns by default.
Pick the tool that matches the job.
Reach for Modal when
- You need best-in-class serverless GPU for model inference or batch jobs.
- Your workload is raw compute, and you already own the app, DB, and auth around it.
- You want a Python-first deploy experience for arbitrary functions.
Reach for a2a cloud when
- You're shipping an agent, not a function — and want the DB, MCP, API, and frontend included.
- You need signed execution receipts and ordered event history on governed execution paths.
- You want scoped grants instead of long-lived secrets and ambient access.
Trust the receipt.
a2a cloud deploys any agent — LangGraph, OpenAI Agents SDK, CrewAI, or custom — and ships it with a managed Postgres database, an MCP server, an API, a frontend, and an Ed25519-signed receipts on governed execution paths. Scoped grants, no ambient production access. One deploy, the whole agent app, with proof.
