Nebula vs quarto
A side-by-side editorial comparison of Nebula and quarto — release velocity, themes, recent moves, and the top alternatives to consider.
Nebula vs quarto: at a glance
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.
What is quarto?
Quarto's VS Code extension moved to MIT and now ships fixes for Positron and citations.
Quarto's VS Code extension ships roughly monthly with a focus on cell editing and Positron integration. After the MIT relicense in 1.137.0, 1.138.0 fixed how Python cells run in knitr documents in Positron, a language-server crash on bad YAML options, and Zotero failing to appear as a citation source. 1.139.0 in October raised the minimum VS Code version and fixed citation and YAML handling.

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.
quarto
2.5INFRA · APIS
Quarto's VS Code extension moved to MIT and now ships fixes for Positron and citations.
◆ Current state
Quarto's VS Code extension ships roughly monthly with a focus on cell editing and Positron integration. After the MIT relicense in 1.137.0, 1.138.0 fixed how Python cells run in knitr documents in Positron, a language-server crash on bad YAML options, and Zotero failing to appear as a citation source. 1.139.0 in October raised the minimum VS Code version and fixed citation and YAML handling.
◆ Where it's heading
Since the relicense, releases have been fixes rather than features, mostly around Positron and the visual editor's citation support. The extension increasingly defers language features to Positron when it provides them.
◆ Prediction
Expect a 1.140 release within about a month with more Positron integration fixes; no new feature area is signalled.
