ggdemetra vs OpenObserve

ggdemetra vs OpenObserve: at a glance
What is ggdemetra?
A ggplot2 layer for seasonal adjustment output, filling in one plot type at a time.
ggdemetra is a thin, focused bridge: it puts RJDemetra's seasonal adjustment results — TRAMO-SEATS and X-13 models — into ggplot2 geoms and autoplot methods. Development runs in short bursts separated by long quiet stretches, and the most recent work has been correcting SI ratio handling rather than adding surface. The API is small enough that a single function rename counts as the notable change in a release.
What is OpenObserve?
After its largest release, OpenObserve is patching the seams.
v0.92.0 landed on 7 August with 836 commits and three new product surfaces - synthetic monitoring, Workflows v1, and an expanded AI observability set - after a long RC series. The two releases since are small: v0.92.1 fixed alert HAVING clause typing and put the MCP server setup page on the OSS build, and v0.92.2 adds a compactor delay setting and backports an MCP 404 fix for deployments running under a base URI. The 0.91 line is still receiving its own backports.

◆ Current state
ggdemetra is a thin, focused bridge: it puts RJDemetra's seasonal adjustment results — TRAMO-SEATS and X-13 models — into ggplot2 geoms and autoplot methods. Development runs in short bursts separated by long quiet stretches, and the most recent work has been correcting SI ratio handling rather than adding surface. The API is small enough that a single function rename counts as the notable change in a release.
◆ Where it's heading
The package has been steadily completing its coverage of the seasonal adjustment output surface: component extractors and autoplot methods in 0.2.3, SI ratio plotting in 0.2.5, then two releases of corrections to make SI ratios behave under TRAMO-SEATS jSA models and when no seasonal component is exported. Alongside that, the naming is being tidied — y_forecast() became raw(), and init_ggplot() shortened the setup boilerplate. This reads as a package approaching the edge of its intended scope and spending its effort on correctness.
◆ Prediction
Two consecutive releases fixing SI ratios under TRAMO-SEATS suggest that code path is the least settled part of the package, so further corrections there are the most likely next move. The entries give no indication of new model families or plot types being planned.
OpenObserve
6.3ANALYTICS
After its largest release, OpenObserve is patching the seams.
◆ Current state
v0.92.0 landed on 7 August with 836 commits and three new product surfaces - synthetic monitoring, Workflows v1, and an expanded AI observability set - after a long RC series. The two releases since are small: v0.92.1 fixed alert HAVING clause typing and put the MCP server setup page on the OSS build, and v0.92.2 adds a compactor delay setting and backports an MCP 404 fix for deployments running under a base URI. The 0.91 line is still receiving its own backports.
◆ Where it's heading
OpenObserve is trying to become the whole monitoring stack rather than the storage layer under one. Synthetic checks, incident workflows, and SLO measurement each replace a separate tool, and incident ingestion from external alert sources hedges the migration path for teams that cannot switch all at once. The MCP work running alongside - open sourced, then given a setup page in the OSS build, then fixed for base-URI deployments - shows the same data being aimed at agent clients rather than dashboards.
◆ Prediction
The post-GA patches are still landing on the new surfaces, so expect another 0.92.x before feature work resumes - most likely hardening synthetic monitoring and Workflows, which are the two least-exercised additions.
