What does Theia integrate with?
We have confirmed 9 integrations for Theia, including Python, Java, C++, Go, YAML, ESLint, NPM and GitHub Pull Requests, plus 1 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://theia-ide.org
Is Theia open source?

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Theia, not the verdict.
