LibreSpeed vs Nebula
A side-by-side editorial comparison of LibreSpeed and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
LibreSpeed vs Nebula: at a glance
What is LibreSpeed?
LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.
LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.
What is Nebula?
Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.
Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.

LibreSpeed
2.5INFRA · APIS
LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.
◆ Current state
LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.
◆ Where it's heading
With the design migration done, releases focus on measurement accuracy and easier Docker deployment. Minor versions arrive every month or two.
◆ Prediction
Expect further accuracy and deployment fixes in 6.3.x; no larger feature is signalled.
Nebula
2.5INFRA · APIS
Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.
◆ Current state
Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.
◆ Where it's heading
The IPv6 work has moved from security fixes to per-platform correctness, and 1.12 turns to throughput. Offloading starting as opt-in, with a stated plan to make it default, sets up the next release cycle.
◆ Prediction
Expect 1.12.x patches for offloading edge cases, and a later release that turns offloading on by default as announced.
