No Sketch Engine logo

Welcome to NoSketch Engine, an open-source project combining Manatee and Bonito and Crystal into a powerful and free corpus management system. NoSketch Engine is a limited version of the software empowering the famous Sketch Engine service, a commercial variant offering word sketches, thesaurus, keyword computation, user-friendly corpus creation and many other excellent features.

Try Sketch Engine trial account - word sketches, thesaurus, keywords, online corpus building and space for your corpora, online availability and technical support. See overview of Sketch Engine versus NoSketch Engine.


For receiving updates about new versions and futures, please subscribe to the NoSketch Engine Google group.


You are free to use the documentation available for commercial Sketch Engine.

System requirements

NoSketch Engine packages are available for a Linux distribution CentOS 7 64 bit. The requirements: 8 GB of RAM; 20 GB of space, SSD is strongly preferred; (CPU): contemporary 64-bit Intel or AMD processor.

NoSketch Engine packages


Manatee is a corpus management and query system. License: GPLv2+.


Bonito is an API interface for the Manatee corpus management system. License: GPLv2+.


GDEX (Good Dictionary Examples) is a Bonito module for sorting concordances according to their suitability as dictionary examples. License: GPLv3.


Crystal is a web interface for Sketch Engine. License: GPLv3.

third party dependencies

You may install python-prctl and Bonito will use it to setup nice process titles for background jobs (that you will see in the output of the ps command and similar).

Bonito RPM package requires python3-prctl, you can ignore the dependency (rpm -ivh ./bonito-open-*.el7.noarch.rpm --nodeps) or you can build python3-prctl RPM package from python-prctl sources (git clone ; cd python-prctl/ ; sed -i 's|name = "python-prctl"|name = "python3-prctl"|' ; ./ bdist_rpm).


Latest stable release

You should always download the latest versions of all components.

Release notes

IMPORTANT: When updating from a version of Manatee before 2.207.2, existing corpora need to be recompiled or updated in-place by executing


for every corpus. If you don't do this, the process will be automatically started as a background job when new indices are needed, making users to wait (up to several minutes for big corpora) until it finishes.

Older releases can be downloaded from the archive.

Bonito (run.cgi) configuration

Bonito configuration file is run.cgi you may run multiple instances just by copying this file and changing the configuration. To enable authentication set _anonymous = False. If you run Crystal on a different hostname than Bonito, you may need to setup CORS headers appropriately, see the top of the run.cgi file.

Crystal (config.js) configuration

# set URL to run.cgi script of bonito
