WorthSignal

Overview

WorthSignal is a free, open-source tool for turning spreadsheet customer records into practical marketing analyses. It suits marketers who work with files rather than notebooks or statistics software, especially those who want to run analyses locally. Its deliberate reliance on classic, simple methods is a useful trade-off for accessibility, but not a fit for teams seeking predictive segmentation or advanced statistical approaches.

Key features

WorthSignal covers nine analysis areas, including RFM targeting, customer lifetime value, customer equity, acquisition and retention budgets, Markov switching ROI, contractual retention, BG/NBD, BG/BB and complaint recovery. It also supports cohort analysis, profitability metrics and a configurable forecast horizon. That breadth gives spreadsheet users a way to examine several customer-value questions in one workflow; the project’s emphasis on simple models makes it better suited to practical analysis than sophisticated statistical work.

It reads XLSX, XLS, XLSM, CSV and JSON files, suggests column mappings, and lets users correct those mappings without changing the uploaded file. Results can be downloaded as Excel or JSON. Input is file-based, with batch refresh rather than continuously updated data, so it suits periodic analysis more than live segmentation. Segments can draw on needs, preferences, values, behavior, demographics, channels, product usage, purchase behavior, engagement, price sensitivity and transaction-derived RFM variables. Predictive segments and anonymous profiles are not supported.

In local mode, analyses run in memory on the user’s computer. The app has no user accounts, advertising, product analytics, telemetry or customer-data database, and says it does not intentionally send uploaded customer data to its maintainer or a third-party API. Hosted use changes the responsibility: the chosen server processes files, and its operator must manage access controls, logs, retention and privacy obligations.

Methods are documented and cited, and the license is AGPL-3.0-or-later; commercial use is allowed subject to its conditions. The app requires Python 3.10 or newer. It can be launched on Windows or Mac, run from a terminal on any operating system, or deployed with Docker; the project also documents deployment to Streamlit Community Cloud from a GitHub repository.

Pricing

WorthSignal — free. The single open-source plan provides the customer analytics toolkit without a paid tier or free-trial clock. That makes it a straightforward option for individual marketers and teams comfortable running open-source software. The trade-off is operational rather than a lower paid tier: users need to run or host the app themselves, and hosted deployments bring server-side privacy and security responsibilities.

Security fixes are maintained on the latest main branch, with no older release branches. Vulnerability reports receive best-effort review, without a formal response-time SLA. Organizations that require guaranteed response times or maintained older versions should account for that before adopting it.

Platforms

WorthSignal supports Linux, macOS, Windows, web and self-hosted deployment. The file-based workflow and Python requirement make it more appealing to users able to launch or deploy the software than to teams looking for a managed service with ongoing data refresh.

Who it's for

Working marketers who already keep customer data in spreadsheets and want segmentation, CLV, retention or ROI analysis without moving into notebook or statistics software are the clearest fit. It is also a reasonable choice for privacy-conscious users who prefer local processing and can manage the software themselves. Teams needing predictive segments, anonymous profiles, live refresh, or formal security response commitments should look elsewhere.

Pros and cons

• Pros: Broad coverage of customer-value analyses, from RFM and CLV to retention and marketing ROI, in a file-based workflow.
• Pros: Local in-memory analysis, no telemetry or customer-data database, and unchanged source files support a privacy-conscious workflow.
• Pros: Free, open-source access with Excel and JSON exports avoids a paid-plan or trial decision.
• Cons: Classic, deliberately simple methods are not advanced statistical approaches.
• Cons: Batch refresh and the absence of predictive segments limit use for continuously updated audience targeting.
• Cons: Self-hosting requires Python 3.10 or newer, and hosted operators must handle data safeguards.
• Cons: Security support has no formal response-time SLA and fixes target only the latest main branch.

Verdict

WorthSignal is a strong fit for spreadsheet-oriented marketers who want free, locally runnable customer segmentation, lifetime value, retention and ROI analyses using documented classic methods. Its main reason to choose it is the combination of broad analysis coverage and local-first handling without a paid plan. Look elsewhere if your work depends on predictive segments, live refresh, advanced statistics or a formal security response commitment.
