Kestra vs Nebula
A side-by-side editorial comparison of Kestra and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
Kestra vs Nebula: at a glance
What is Kestra?
Kestra's feed is design-system package releases while 2.1.0 waits past its first RC.
Kestra's recent entries are frontend package releases. Design-system v0.7.0 changed the build setup and v0.7.1 shipped with new plumage and topology packages, all licensed for npm on November 6. Kestra 2.1.0-rc1 was tagged on October 20 with no notes, and no final 2.1.0 has appeared.
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.
Kestra vs Nebula: editorial side-by-side
Kestra
5.0INFRA · APIS
Kestra's feed is design-system package releases while 2.1.0 waits past its first RC.
◆ Current state
Kestra's recent entries are frontend package releases. Design-system v0.7.0 changed the build setup and v0.7.1 shipped with new plumage and topology packages, all licensed for npm on November 6. Kestra 2.1.0-rc1 was tagged on October 20 with no notes, and no final 2.1.0 has appeared.
◆ Where it's heading
Kestra is splitting its UI into separately published npm packages, which suggests the topology and design components may be reused outside the main app. Product release notes are absent from this feed.
◆ Prediction
Unclear from these entries; a 2.1.0 release or further package versions are the likely next items.
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.
