FAQ
What is CacheSphere, in one sentence?
CacheSphere is a language intelligence layer for technical decisions: it helps humans and AI compare real tradeoffs, pressure-test default recommendations, and fall back to a curated catalogue when they need evidence.
Is it free?
The core site and MIT-licensed data are free to use and self-host. Hosted packaging, support, and paid access are still early-stage; see Pricing & access for the current state.
Is it a course or tutorial site?
No. It is for decision support and orientation: compare languages, inspect tradeoffs, and get grounded quickly before you commit to a tool, stack, or extra subsystem.
Does it replace official docs?
No. CacheSphere is the layer you use before or alongside official docs when you are deciding what to use, what to keep simple, or whether another language is worth the complexity.
Can I use the JSON in my product?
Yes, under the MIT licence. Preserve licence notices and attribute CacheSphere when you quote or closely summarise the data in user-visible output. See llms.txt for agent-oriented guidance.
Will the API work on the public website?
/api/languages.json is static and usually available anywhere the site is hosted. /v1/… routes need
the Node server or equivalent deployment. Details are in Troubleshooting.
How fresh is the data?
The catalogue improves over time. Treat code and ecosystem notes as grounded starting points, not final authority, especially for fast-moving tools and runtimes.
Who is it for?
Solo developers, small teams, and AI tools that need a better answer than “use the default.” It is especially useful when you are deciding whether to stay in one language, add another one for a bottleneck, or justify a recommendation.
Who runs it?
CacheSphere is built by Idaluna Labs. Contact: [email protected].
