GitLab acquires Gitter, which develops chat rooms for code repositories, with plans to open source the code
Jordan Novet / VentureBeat :
Context & Ripple Effects
GitLab has been assembling an open-source alternative to GitHub on venture money: a $1.5M seed round in 2015, a $4M Series A from Khosla Ventures, then a $20M Series B led by August Capital that took the company past 100 remote employees. Buying Gitter extends that playbook beyond code hosting into developer communication.
The deal matters because chat is where development teams actually coordinate, and by committing to open source Gitter's code rather than folding it into a proprietary product, GitLab is positioning the acquisition as a trust signal to the same open-source community it has been courting since its Series A.
First-order effects
- Gitter users gain the ability to inspect, self-host, and modify the chat software, since GitLab has committed to releasing the code under an open-source license.
- GitLab folds repository-adjacent chat directly into its platform, closing a gap against GitHub's ecosystem without building the feature from scratch.
Second-order effects
- Hosted chat vendors selling to engineering teams now face a free, open-source option backed by a well-funded GitHub competitor, pressuring their pricing for developer-focused plans.
- GitHub must decide whether bundled team communication becomes a differentiator worth matching, since GitLab can now pitch code hosting, review, and chat as one open-source package.
Third-order effects
- If the pattern holds, developer-tool acquisitions increasingly ship as open-sourced code used as a competitive wedge against proprietary incumbents, making license terms part of M&A strategy.
- Developer workflows consolidate toward single platforms spanning hosting, CI, and communication, raising the stakes of the GitLab-versus-GitHub contest for which stack teams standardize on.
The trend: DevOps platforms are consolidating code hosting, automation, and team communication into single open-source stacks, with acquisition-and-open-source moves as the weapon of choice for challengers.
