For a close answer, could u please tell about your Context and Approach? it mean if you are looking for a tool into urban design dimension, i think we need to grab a approach. such as SIA method and tools like SS in Social-behavior one.
Content analysis is a research technique used to make replicable and valid inferences by interpreting and coding textual material. By systematically evaluating texts (e.g., documents, oral communication, and graphics), qualitative data can be converted into quantitative data. https://www.terry.uga.edu/management/contentanalysis/research/

*since content analysis is relatively weak as compared to grounded theory or hermeneutic phenomenology, substantiate content analysis with thematic analysis and descriptive phenomenology
It depends on your data sources. If you are doing a content analysis of urban plans, for example, a tool like NVivo is useful or you can even do it manually fairly easy by creating a framework in Microsoft Excel to code information and statements from the documents. For my recent research I used NVivo mostly for "open coding" and Excel for more directed observations (eg. completing a checklist of what was or was not present in the document).
If you're looking instead at something like a map to understand neighbourhood change, a tool like QGIS or ArcGIS would be useful (however, I would consider this to be spatial analysis more so than content analysis).
