What is Grav?

Grav's 1.7 line keeps taking small patches after its security backport burst.

Grav's 1.7 branch shipped four patches between 10-31 and 11-04. 1.7.53.7 and 1.7.53.8 backported Grav 2 security fixes and web-server protection rules; 1.7.53.9 fixed :80 redirects behind HTTPS proxies; 1.7.53.10 makes cache purges report which file failed and why.

What is Rivet?

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

Grav vs Rivet: editorial side-by-side

G
Grav
DEVOPS
5.0

Grav's 1.7 line keeps taking small patches after its security backport burst.

◆ Current state

Grav's 1.7 branch shipped four patches between 10-31 and 11-04. 1.7.53.7 and 1.7.53.8 backported Grav 2 security fixes and web-server protection rules; 1.7.53.9 fixed :80 redirects behind HTTPS proxies; 1.7.53.10 makes cache purges report which file failed and why.

◆ Where it's heading

Security work lands on Grav 2 first and is then carried back to 1.7, and the pace of that carry-back jumped: one patch on 10-24, three within about four hours. The fixes moved from individual code paths to the web-server rules that sit in front of the application. Among web servers, only Apache sites get those rules on upgrade; IIS, nginx, Caddy and lighttpd sites must copy them by hand, so protection on 1.7 now depends on the host's web server.

◆ Prediction

Expect more 1.7.53.x patches mirroring 2.x security fixes, plus small follow-up fixes like the proxy redirect in 1.7.53.9. The entries don't show how long 1.7 support continues.

Rivet
DEVOPS
7.5

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

◆ Current state

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

◆ Where it's heading

Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.

◆ Prediction

Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
