Private and open-source alternatives to IntelliJ IDEA
9 code editors rated against the same public privacy criteria as IntelliJ IDEA (JetBrains), with our picks first.
Why look for an alternative?
- Open source: partial. The core platform is Apache 2.0 and available as open-source builds, but the standard IntelliJ IDEA distribution includes proprietary features.
- No trackers or telemetry: no. The website loads Google Tag Manager and shares data with third-party advertising partners. In the IDE, anonymous usage statistics are opt-in.
- No ads or data sales: partial. Funded by paid subscriptions, with no ads in the IDE. The privacy policy allows sharing website data with advertising partners to market JetBrains products.
- Independent audit: no. No independent audit is published.
