The short version

  • Each has a real cost: Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations; SolidJS much smaller ecosystem than React, so many problems have no off-the-shelf library
  • They diverge on capability: Deno Deploy covers Edge Functions, SolidJS covers No virtual DOM.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

SolidJS

  • Much smaller ecosystem than React, so many problems have no off-the-shelf library
  • The React-like syntax is misleading: components run once, and React habits produce subtle bugs
  • Smaller hiring pool and fewer learning resources than the mainstream frameworks

Yes, open source under the MIT licence.

Deno 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.

Source
SolidJS: Is SolidJS just React without the virtual DOM?

The syntax is similar but the model is not. Solid components run once and reactivity is fine-grained, so patterns that are correct in React can be wrong in Solid.

Deno 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.

Source
SolidJS: Why is SolidJS fast?

It compiles away much of the framework and updates individual DOM nodes directly, rather than re-rendering components and diffing a virtual DOM.

Deno 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.

Source
Deno Deploy: What security features does Deno Deploy provide?

Deno Deploy features an opt-in permission system to mitigate supply chain attacks. Permissions can be explicitly granted for file, network, and environment access, running code securely by default.
