Tailscale has the clearer adoption lead as of August 2026, ranking #108 overall compared with OpenVPN at #209. OpenVPN is closing the gap: it climbed 19 positions, while Tailscale dropped 9 positions. By spend, Tailscale ranks higher (#197 versus #244), which shows where more of the measured software budget currently sits. The switching signal adds useful context: after leaving OpenVPN, some companies adopted GitHub or Atlassian. The practical takeaway is to separate market position from product fit: the rankings show which tool is more established and where buying momentum is moving, but they do not measure features, price, or quality. Use those signals to build a shortlist, then decide against your own workflows and requirements.
