FlowDelta
Compare n8n workflow versions, review downstream impact, and create an editable acceptance plan. Local browser processing; Markdown and PDF handoff.
About FlowDelta
FlowDelta performs static graph analysis on n8n automation files to detect differences between workflow revisions. Designed for automation consultants and platform engineers, the utility accepts two n8n JSON export files, parsing node configurations, connection pathways, and parameter blocks. By evaluating graph topology, the tool highlights added, deleted, and modified nodes alongside modified parameter settings, even when wire connections between steps remain visually identical.
Beyond raw visual diffing, the utility computes downstream dependency impacts across execution pathways. When an engineer updates an API query, webhook trigger, or data transformation script, the analysis identifies every subsequent node affected by the modification. Users can review field-level changes side by side, append custom implementation notes, and establish targeted test instructions for each altered operational component.
All graph comparisons and document rendering run entirely client-side inside the web browser without sending proprietary workflow schemas to external servers. Platform specialists can convert comparison outputs into structured client acceptance packets, exporting formatted Markdown documents or printable PDF files for stakeholder sign-off and release auditing. The project is hosted on GitHub Pages and operates with no account creation or subscription requirements.

FAQ
Does FlowDelta upload my workflow?
Workflow comparison and report generation run locally in your browser. Download the handoff before leaving; refreshing clears the workspace.
Does FlowDelta execute my tests?
FlowDelta drafts editable acceptance checks. Execute them in your n8n test environment, then record observations and select each outcome.
What export formats are supported for client documentation?
Users can export comparison summaries, downstream impact evaluations, and acceptance testing notes as standard Markdown files for version repositories or print them directly to PDF for client deliverables.
Can the tool detect changes when node wiring remains the same?
Yes. The diffing engine inspects deep node parameters, authentication profiles, webhook endpoints, and JavaScript code blocks, catching configuration modifications even when the visual flow layout between nodes has not changed.
How can users self-host FlowDelta?
Because FlowDelta is built as a static web application, users can clone the repository from GitHub and serve the static assets locally or host them on their own private web servers without complex backend infrastructure dependencies.
