International Conference on Software and Systems Reuse, Product Lines, and Configuration (VARIABILITY 2026): First Call for Demos and Tools

[George Angelos Papadopoulos]

*** First Call for Demos and Tools ***

International Conference on Software and Systems Reuse, Product Lines,

and Configuration (VARIABILITY 2026)

29 September - 2 October 2026, 5* St. Raphael Resort and Marina

Limassol, Cyprus

https://conf.researchr.org/home/variability-2026

VARIABILITY is a new conference that has been merged of three prominent conferences

focussing on software and systems variability, configuration and reuse: SPLC (the 

International Systems and Software Product Line Conference, 29 successful editions, 

ranked as a top conference), VaMoS (the International Working Conference on Variability

Modelling of Software-Intensive Systems, 19 successful editions), and ICSR (the 

International Conference on Systems and Software Reuse, 22 successful editions). 

The Demos and Tools Track at VARIABILITY 2026 invites compelling live presentations

and submissions of innovative tools, practical demonstrations, and curated datasets that 

support research and practice in software and systems product line engineering, reuse,

and configuration.

This track provides a forum for researchers and practitioners to showcase academic or 

commercial tools, demonstrations of novel techniques, and datasets that contribute to the

advancement of software and systems reuse, software product lines and configurable 

systems. Accepted contributions will be featured both during the main conference (via oral 

presentations) and in interactive exhibition spaces (e.g., demo booths or poster/demo 

sessions during breaks).

This track provides an opportunity to illustrate the practical impact of new ideas and to 

foster interaction between researchers and practitioners that address real-world variability 

challenges.

Topics of Interest

We welcome submissions on all topics related to tool support and datasets for product 

lines and variable/configurable software systems, including (but not limited to):

Core Product Line Engineering Techniques

• Feature modeling

• Variability management

• Product Line Architecture

• Validation and verification

• Product derivation and generation, including build systems and CI

• Product-line testing and further analyses

• Optimization and measurement of non-functional properties

• Language product lines

Application Domains and Contexts

• Software-intensive and cyber-physical systems

• Web and cloud-based systems, including microservices

• Internet of Things

• Automotive and industrial automation

• Consumer electronics

• Software ecosystems and multi-product lines

Submission Guidelines

Submissions must describe either (1) a new tool or prototype; (2) a novel extension to an

existing tool; (3) a practical demonstration of an approach; (4) a new or curated dataset 

relevant to variability and reuse; (5) a significant update to a previously published tool or 

dataset (include a clear description of new contributions).

Each submission must include:

• A paper of up to 4 pages, including references and figures.

• An optional appendix of up to 2 pages (not included in the proceedings), describing the

planned live demonstration or dataset usage scenario.

• A link to a short video (max. 5 minutes) illustrating the tool, demonstration, or dataset

in action.

Papers should briefly describe the theoretical foundation, with a focus on practical aspects

such as software architecture, implementation decisions, usage methodology, and 

validation through case studies or benchmarks.

Public availability of tools and datasets (preferably under open-source/open-data licenses)

is strongly encouraged. Where availability is not possible, submissions should explain the 

reasons.

All submissions must adhere to the LNCS (Springer) format. Please refer to the official LNCS

template at https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines . 

Submissions must be in PDF format and submitted via EasyChair:

https://easychair.org/my/conference?conf=variability2026 (select “Demonstrations and

Tools Track”).

Evaluation Criteria

Each submission will be reviewed by at least three members of the Program Committee. 

Reviewers will evaluate:

• Relevance to the VARIABILITY community

• Technical soundness and artifact maturity

• Novelty of the contribution

• Quality of the written description and video demonstration

• Clarity in the presentation of implementation details, usage, or dataset structure

• Positioning with respect to existing tools/datasets/practices

This track follows a single-blind review process.

Presentation and Publication

Accepted papers will appear in the VARIABILITY 2026 Companion Proceedings, published

in the Springer Lecture Notes in Computer Science (LNCS) series.

At least one author of each accepted paper must:

• Register for the full conference, and

• Present the contribution at the event.

• Notification of Acceptance: 21 June 2026

• Camera-Ready Submission: 15 July 2026

• Author Registration: 15 July 2026
