A Stack Overflow for Teams alternative

You can a bit think of Talkyard as StackOverflow for Teams (, but open source.

Talkyard is for Q&A, just like Stack Overflow, but also intended for ideation & bigger open-ended discussions. And works for creating public communities (not only company internal) around your products (or hybrid partly-public-partly-internal).

Stack Overflow is primarily for Q&A, although you can use it for open-ended discussions too. It has more integrations and better support and uptime guarantees, content and users analytics, and compliance related enterprise features. It's a bigger company, less risky.

Both Stack Overflow and Talkyard are threaded. Stack Overflow limits the threading depth to two (answers and flat comments), which can make Stack Overflow simpler to understand and use, but can also be a small hinderance to larger discussions.

Talkyard has partly implemented anti-cognitive biases features that deal with things like group think, appeal-to-authority (these features are optional), anchoring bias.

Below, €3 means that the feature on that row, is included in Talkyard's €3 price plan (that is, €3 per active employee and month). And $0 in Stack Overflow's column, means that the feature is free at Stack Overflow, for up to 50 employees. means the feature is missing.

Probably there's some error in the table below, or will be, as time goes by. (This was last updated in October 2023.)
