KLINK vs OpenCTI
A side-by-side editorial comparison of KLINK and OpenCTI — release velocity, themes, recent moves, and the top alternatives to consider.
KLINK vs OpenCTI: at a glance
What is KLINK?
Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.
KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.
What is OpenCTI?
OpenCTI spends a release unblocking queues and hardening upserts
7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.

KLINK
2.5ANALYTICS
Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.
◆ Current state
KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.
◆ Where it's heading
The direction is from fixed panel toward general instrument. Hard-coded linkage pairs gave way to dynamic pairing, the built-in map grew from 18 to 50 markers, the map itself was then moved out to the norSTR package, and the app now accepts custom maps in several file formats and decimal conventions. Method capability tracks the upstream pedsuite rather than KLINK itself: special lumping in pedprobr and pedmut is what allowed complex mutation models in common pedigrees, and the newest release pins pedtools 2.11.0 and pedprobr 1.1.0 for faster likelihoods and better handling of looped pedigrees. Much of the remaining work is unglamorous casework ergonomics, replacing stray Norwegian text in Excel output, controlling table heights, fixing karyogram colours.
◆ Prediction
With the map externalised and custom maps loading from multiple formats, the likeliest next step is broader marker-panel coverage through norSTR rather than changes in KLINK itself. Method gains should continue to arrive as pedprobr and pedmut version bumps.

OpenCTI spends a release unblocking queues and hardening upserts
◆ Current state
7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.
◆ Where it's heading
The platform's feature energy went into the connector catalog and integrations rework in July, and the releases since have been consolidating: mass operations on relation times, shareable saved searches, and now a pass over ingestion robustness. Adding score to more entity types continues the slow enrichment of the data model that runs underneath the feature work.
◆ Prediction
Given score arriving on three entity types in one release, expect it to keep spreading across the data model, and the queue-blocking class of bug to draw more worker-side hardening.
