The short version

  • Each has a real cost: Redis licensing changed from BSD to AGPL in 2025, impacting open-source usage; SolidJS much smaller ecosystem than React, so many problems have no off-the-shelf library
  • They diverge on capability: Redis covers In-memory data store, 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.

Redis

  • Licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • All data must fit in memory, limiting scalability to available RAM
  • No built-in support for multi-tenancy
  • Limited transaction support compared to traditional databases

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

Answered from the vendors’ own pages

Redis: Is Redis open source?

Redis was open source under the BSD license since its inception in 2009 and has remained open source. However, in 2024-2025, Redis Labs changed licensing to source-available and AGPL, prompting the creation of Valkey, a BSD-licensed open-source fork.

Source
SolidJS: Is SolidJS free?

Yes, open source under the MIT licence.

Redis: What is Redis used for?

Redis is an in-memory data structure store used primarily as a cache, database, and message broker. It provides high-speed data access for real-time applications, sessions, leaderboards, real-time analytics, and other use cases requiring fast data retrieval.

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.

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.
