What It Is

Kraken BLAST is a commercial, parallelized implementation of NCBI BLAST developed by Research and Testing Laboratory of the South Plains. It uses one Kraken BLAST master node and multiple Tentacle Servers nodes to organize clusters, high-performance computers, or ordinary workstations into a distributed computing system for running high-throughput BLAST tasks in parallel.

Core Capabilities and Developer Perspective

Functionally, it emphasizes automatic scaling based on the number of available nodes, including scaling up or down while a job is running. For large query sets and database sets, it can reportedly achieve linear or even superlinear speedups. In terms of output, it currently returns only XML blast output, but the text explicitly states that it matches standard NCBI BLAST output exactly, which is helpful for existing XML parsing workflows. Platform support is currently limited to Windows, requiring Windows XP SP3 or later. The page mentions future Tentacle support for MacOS X, Linux, and UNIX, but does not show that this has been implemented. It can be deployed on self-owned workstations, servers, clusters, or HPC environments, making it self-hosted software. The main text does not disclose an API or SDK, nor does it show an open-source repository, so it appears to be more of a closed-source commercial desktop/node-based tool.

Pricing and Purchase

Pricing appears to be based on perpetual or one-time licenses, though the main text does not specify any maintenance period. Kraken BLAST costs $500 each for 1-3 licenses, $300 each for 4-6 licenses, and $150 each for 7-9 licenses. Tentacle is charged separately: $100 each for 1-9 licenses, with lower unit prices at larger volumes. Normal distributed use also requires at least two computers running Tentacle, so the total cost cannot be judged by the Kraken main program alone. All orders are handled by email, and payment methods are not specified.

Pros and Cons

Its advantages are that it provides distributed parallel optimization for the clearly defined scientific computing use case of BLAST, runs on local computing resources, and produces results compatible with NCBI BLAST XML. The drawbacks are also clear: it currently supports only Windows and offers a single output format; separate Tentacle licensing adds budget complexity; and it lacks API, SDK, modern integration guidance, and detailed documentation. More importantly, the news section appears to stop at a 2011 Beta version, so maintenance activity and production readiness should be carefully verified before purchase.

Who It’s For and Access from China

It is best suited to laboratories and bioinformatics teams that have multiple Windows machines or local HPC resources and need to run BLAST in batches. If a team relies on Linux clusters, containerization, or automated pipelines, standard NCBI BLAST or other parallel BLAST workflows may be a safer choice. There is no basis in the main text for assessing access from China, so it should be marked as unknown. Purchasing, trials, and support all require email contact, and cross-border payment methods also need to be confirmed separately.
