ProcessOn review

ProcessOn is a browser-based tool for making diagrams and mind maps, with AI-assisted generation and real-time collaboration. It covers common business formats such as flowcharts, swimlane diagrams, ER diagrams, UML, BPMN, network maps and floor plans. For mind maps, AI can generate a starting point from a prompt, including formats such as meeting outlines, to-do lists and SWOT analyses.

It also supports Markdown and inserted LaTeX formulas, and lets users store documents in the cloud with historical versions available. For moving work between tools, ProcessOn lists Visio and Mermaid as import formats, and Visio, PDF, PNG and SVG as export formats. Templates, sharing and cloud storage round out the product. The main appeal is breadth: it combines diagramming, mind mapping and team editing in one online workspace. It is not just a flowchart maker, but the pricing tiers determine how much of its export and collaboration capacity you get.

ProcessOn’s strongest case is the range of diagrams available in one product. Teams can move between flowcharts, swimlanes, ER diagrams, UML, BPMN, network maps and floor plans rather than adopting a separate tool for each format. Mind-map generation adds a faster way to start common planning documents, with prompts for meeting outlines, task lists and SWOT analyses.

Its collaboration and file features are useful for shared work: multiple people can edit a diagram in real time, and cloud storage keeps documents and historical versions available. Markdown and LaTeX formula support give users options for adding structured text and mathematical notation.

The paid plans also remove some practical constraints. Personal Monthly costs $8.90 per user per month; Personal Yearly is $69 per user per year, equivalent to $5.75 per month. Both list unlimited files and collaborators, attachment uploads and PDF and Word exports. The Lifetime Plan is listed at a one-time $199 per user and includes full export capabilities. That gives individuals a choice between monthly billing, an annual discount and a one-time purchase.

The free plan is a limited way to assess ProcessOn for ongoing work. It includes one user seat, nine personal files and up to three collaborators. Its listed exports are standard-resolution PNG, JPG, POS and Visio; PDF and Word exports and high-resolution image downloads appear on the Personal plans instead. Users who need more than a small set of personal diagrams will likely have to pay.

Pricing is less clear for teams. The Team Plan is custom-quoted, and exact seat limits are not published. The Enterprise Plan also requires a custom quote; private deployment, SSO and custom user management are listed, but exact usage limits are not. Add-on and overage costs are not published either, which makes it harder to estimate total spend before contacting sales.

The pricing listing also advertises a seven-day Personal trial and a 14-day Lifetime trial, but does not provide further trial terms in the published details. ProcessOn covers a lot, but buyers should confirm team costs and any usage limits before switching.

According to the pricing information checked on November 7, 2026, ProcessOn has a free plan, but it is capped at 1 user, 9 personal files and 3 collaborators. Its exports are standard resolution and include PNG, JPG, POS and Visio. The Personal Monthly plan costs $8.90 per user per month. The annual option is $69 per user per year, equivalent to $5.75 per month, billed upfront. Both paid Personal plans include 1 seat, unlimited files and collaborators, attachment uploads and PDF and Word exports. That is the main price trade-off: pay monthly for flexibility, or pay annually to reduce the monthly equivalent. A Lifetime plan is listed at $199 per user as a one-time purchase, with unlimited files and collaborators and full export capabilities. Team and Enterprise prices require custom quotes; exact seat and usage limits are not published. Add-on and overage costs are also not published. The listed trial periods are 7 days for Personal and 14 days for Lifetime, so confirm eligibility and renewal terms before signing up.

ProcessOn supports importing Visio and Mermaid files, and exports to Visio, PDF, PNG and SVG. The Free plan lists standard-resolution PNG, JPG, POS and Visio exports; paid Personal plans add PDF and Word exports. Before switching, check whether the formats you need are available on your plan and test a representative file for any formatting changes. The product description says documents sync to the cloud and historical versions are available, but it does not specify retention periods or a bulk-export process. Those details are worth confirming if you are moving a large library or need an archive before leaving. ProcessOn can also make collaboration part of the switch: the free plan allows up to 3 collaborators, while paid Personal plans list unlimited collaborators. Team and Enterprise seat limits are not published. We were not given Reddit posts or comments to substantiate reasons people leave, so we can't reliably say what Reddit users report. The documented reasons to compare alternatives are clearer: the free file cap, unpublished team pricing and undisclosed add-on costs.
