mrbayes vs OpenCTI
A side-by-side editorial comparison of mrbayes and OpenCTI — release velocity, themes, recent moves, and the top alternatives to consider.
mrbayes vs OpenCTI: at a glance
What is mrbayes?
mrbayes spent 2026 auditing its own Bayesian MR estimators for coding errors.
mrbayes wraps Stan and JAGS implementations of Bayesian Mendelian randomization estimators — IVW, MR-Egger, radial Egger, and their multivariable forms. Most of the visible history is packaging work: dependency trimming, conditional examples so the package installs where JAGS will not compile, a maintainer handover. The 0.5.3 release in July 2026 breaks that pattern with a dense list of fixes inside the model code itself.
What is OpenCTI?
OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
The mainline is working through the consequences of the connector catalog redesign, with each release closing gaps around it: filters and saved searches became shareable, dashboards can reuse them, and background tasks can now edit relationship start and stop times in bulk. Alongside that, an LTS branch is being maintained in parallel — 7.260309.0-lts.7 backports the security fixes and dependency updates from the recent mainline releases without any of the feature work.

◆ Current state
mrbayes wraps Stan and JAGS implementations of Bayesian Mendelian randomization estimators — IVW, MR-Egger, radial Egger, and their multivariable forms. Most of the visible history is packaging work: dependency trimming, conditional examples so the package installs where JAGS will not compile, a maintainer handover. The 0.5.3 release in July 2026 breaks that pattern with a dense list of fixes inside the model code itself.
◆ Where it's heading
The package has moved from packaging upkeep into a correctness-audit phase. 0.5.3 fixes a hardcoded three-exposure loop in MVMR-Egger reporting, a broken joint-prior branch, a sigma parameterization error in radial Egger, and several prior specifications — the profile of a maintainer reading their own model files closely rather than responding to bug reports. Platform work continues underneath: an R 4.3.0 floor inherited through a transitive dependency chain, and segfault fixes on macOS ARM.
◆ Prediction
Expect further audit-driven patches to the remaining rjags and Stan model files rather than new estimators; the fixes in 0.5.3 cluster in the Egger variants, which suggests that is where the reading is still in progress.

OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
◆ Current state
The mainline is working through the consequences of the connector catalog redesign, with each release closing gaps around it: filters and saved searches became shareable, dashboards can reuse them, and background tasks can now edit relationship start and stop times in bulk. Alongside that, an LTS branch is being maintained in parallel — 7.260309.0-lts.7 backports the security fixes and dependency updates from the recent mainline releases without any of the feature work.
◆ Where it's heading
Two things are running at once. The product arc is about making the platform's own surfaces composable — a faceted connector marketplace, reusable filters, workflow approval and draft metadata — rather than adding threat-intel primitives. The engineering arc is a maintained LTS channel that gets security parity and nothing else, which is how a project behaves once it has deployments it cannot ask to track weekly releases.
◆ Prediction
Expect the mainline to keep landing XTM Hub integration and workflow-governance work at roughly a weekly cadence, with a matching lts.8 backport following whenever the next batch of security fixes accumulates.
