Cronicle vs Nebula
A side-by-side editorial comparison of Cronicle and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
Cronicle vs Nebula: at a glance
What is Cronicle?
Cronicle closes three permission holes in two days, including API key exposure.
After weeks of single-dependency bumps, Cronicle shipped two security fixes. 0.9.141 restricts run_event overrides so a plugin cannot be swapped, and 0.9.142 blocks restricted accounts from chain reactions and stops API keys leaking into objects and audit metadata. Earlier October releases bumped pixl-tools, pixl-mail and sanitize-html.
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.

Cronicle
5.0INFRA · APIS
Cronicle closes three permission holes in two days, including API key exposure.
◆ Current state
After weeks of single-dependency bumps, Cronicle shipped two security fixes. 0.9.141 restricts run_event overrides so a plugin cannot be swapped, and 0.9.142 blocks restricted accounts from chain reactions and stops API keys leaking into objects and audit metadata. Earlier October releases bumped pixl-tools, pixl-mail and sanitize-html.
◆ Where it's heading
The 0.9.x line is in maintenance, but the focus has moved from upstream vulnerabilities to Cronicle's own permission model. Releases arrive every few days.
◆ Prediction
Expect more permission and privilege fixes in the next 0.9.x builds; no feature work is visible.
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.
