Short on time? Here's the quick answer
We've tested both tools. Here's who should pick what:
OpenComputer
Deploy AI agents as TypeScript functions on real Linux machines
Best for you if:
- • You want to try before committing
- • You need AI agents features specifically
- • Write an agent as a TypeScript function and deploy it live in seconds.
- • Every session runs on a real Linux machine with full egress, tools, and MCP support.
AWS Lambda
Run code without managing servers, pay only for compute time
Best for you if:
- • You need serverless features specifically
- • AWS Lambda lets you run code without provisioning servers-just upload your function and it scales automatically
- • It executes code in response to events from 200+ AWS services, charging only for compute time used

Watch out
PAYG rates kick in after credit exhausted
Strengths
- +Fast deployment: write a function, deploy in seconds
- +Secure by design: keys never enter the runtime
- +Flexible: bring your own model keys or use theirs
- +Durable sessions that hibernate and resume
- +Pay-as-you-go with free credit to start
Weaknesses

- -Usage-based pricing can be unpredictable for long-running sessions
Key features
AWS Lambda
Run code without managing servers, pay only for compute time
Lambda pioneered serverless compute and remains the default choice in the AWS ecosystem.
Watch out
Duration billing rounds up to the nearest millisecond, but memory billing is per-GB-second at allocated memory (not used memory). Allocating 1 GB but using 200 MB still bills for 1 GB, right-sizing memory is critical
Strengths
- +Industry-standard serverless platform
- +Integrates with entire AWS ecosystem
- +Scales automatically to any load
- +Pay only for compute time used
- +Supports many languages and runtimes
Weaknesses
- -Cold starts can affect latency
- -Complex pricing model
- -15-minute execution time limit
- -Debugging can be challenging
- -Vendor lock-in with AWS services
