Azure Functions vs Deno Deploy
The short version
- Each has a real cost: Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that; Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Azure Functions
- Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
- The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
- Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
- Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward
Deno Deploy
- Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
- Less mature than established serverless platforms; newer company and platform
- 1GB deployment size limit may restrict larger applications
- 512MB memory limit lower than some competitors for memory-intensive workloads
- Smaller user base and community compared to Lambda or Netlify

Answered from the vendors’ own pages
Azure Functions: Does Azure Functions have a free tier?
Yes, Azure Functions includes a monthly free grant of 1 million requests and 400,000 GB-seconds on the Consumption Plan, or 250,000 executions and 100,000 GB-seconds on Flex Consumption.
SourceDeno Deploy: What does Deno Deploy's free tier include?
Deno Deploy free tier includes 1 million requests per month, 100 GB of outbound bandwidth, 50 milliseconds of CPU time per request, 50 custom domains, 1 GiB of KV storage, and up to 5 team members.
SourceAzure Functions: What is Azure Functions' pricing model?
Azure Functions uses usage-based pricing. Consumption plans charge per second of resource consumption and per execution, measured in gigabyte-seconds and rounded to the nearest 128 MB.
SourceDeno Deploy: What are Deno Deploy's Pro plan features and pricing?
Deno Deploy Pro costs $20/month and removes request limits, increases KV storage to 5GB, and includes priority support. Additional storage beyond 5GB costs $0.75/GiB.
SourceAzure Functions: What is the minimum execution time for Azure Functions?
The minimum execution time is 100 milliseconds on Consumption plans. Premium plans charge based on core seconds and allocated memory.
SourceDeno Deploy: What are the deployment size and memory limits for Deno Deploy?
The total size of all files within a deployment (source files and static files) should not exceed 1 gigabyte. Applications have a maximum memory allocation of 512MB.
SourceDeno Deploy: Does Deno Deploy support TypeScript natively?
Yes. Deno Deploy runs TypeScript natively with zero-configuration TypeScript support. Code can be written in TypeScript or JavaScript and runs on the same V8 engine.
