ProcessOn

ProcessOn is an online diagramming tool for creating flowcharts, mind maps, and other visual diagrams. Its listed formats include swimlane diagrams, BPMN, UML, network topology diagrams, ER diagrams, and organizational charts. ProcessOn AI adds tools for mind maps, flowcharts, Mermaid, Markdown, and equations. Users can collaborate online and share diagrams through links. Flowchart files save to cloud storage in real time, synchronize across devices, and retain traceable version histories. The service imports Visio, XMind, Markdown, Mermaid, Excel, and POS files, and lists exports including PNG, PDF, PPT, SVG, Excel, and Word. The free plan is free forever and allows 9 personal files and up to 3 collaborators; it has partial download formats. The Personal Edition lists unlimited personal files, collaborators, and download formats, with a 7-day trial shown, while the Lifetime Edition lists those allowances and lifetime ownership without renewal. Prices for both paid editions are not shown. ProcessOn is available on Android, iOS, and web, with no desktop app listed. The site states compliance with ISO/IEC 27001 and GDPR, SOC 2 Type II-audited cloud infrastructure, and SSL/TLS encryption for data transmission.

ProcessOn combines diagram creation with cloud synchronization and collaboration across web and mobile platforms. The free tier has file, collaborator, and download-format limits; paid-edition prices are not shown.

It suits people creating diagrams who want cloud saving, version history, and online collaboration. Teams needing more than 9 personal files or 3 collaborators can review the paid editions, though prices are not shown.

ProcessOn is a cloud diagramming workspace for flowcharts, mind maps, process models, and technical schematics, with web, Android, and iOS access. It suits individuals and teams that need shared editing and broad file interchange more than a desktop-native application. Its free tier is useful for light work, while serious multi-file collaboration requires a paid edition or a willingness to work within tight caps.

Overview

ProcessOn brings many diagram families into one online editor: flowcharts, swimlane diagrams, BPMN, UML, network topologies, entity-relationship diagrams, organizational charts, and mind maps. Real-time multi-person editing and link sharing make it practical for distributed reviews and workshops. Files save continuously to cloud storage, synchronize between devices, and retain traceable historical versions, so recovering an earlier iteration is part of the workflow rather than a separate backup task.

Its security position is geared toward organizational use. ProcessOn states ISO/IEC 27001 and GDPR compliance, cloud infrastructure meeting SOC 2 Type II audit requirements, and SSL/TLS encryption for data in transit. API integrations with office software and third-party applications, including DingTalk and Enterprise WeChat, can connect diagrams with communication workflows.

Key features

AI and diagram coverage

ProcessOn AI provides AI mind maps, AI flowcharts, Mermaid, Markdown, and equation tools. Those options are most relevant when a team starts from structured text or needs a quick visual outline rather than drawing every element manually.

Import, export, and history

Imports cover Visio, XMind, Markdown, Mermaid, Excel, and POS. Exports include PNG, PDF, PPT, SVG, Excel, Word, JPG, POS, XMind, FreeMind, and Visio. That breadth helps when diagrams must move into presentations, office documents, or other modeling tools. Version history and synchronized cloud files support iterative work, although the free tier limits how many personal files you can keep.

Pricing

ProcessOn uses a freemium model with a 7-day trial. The Free Version costs free, billed free forever. It allows 9 personal files and up to 3 collaborators, partial file-download formats, one custom mind-map theme, and nine custom flowchart shapes. This is adequate for occasional diagrams, but the file and collaboration ceilings arrive quickly in an active project or small team.

The Personal Edition has custom pricing; a monthly option and a 7-day trial are shown. It provides unlimited personal files, collaborators, and download formats, making it the logical upgrade for ongoing individual or team work. The Lifetime Edition also has custom pricing, is offered as a lifetime option, and includes the same unlimited files, collaborators, and download formats with ownership that requires no renewal. Membership fees are nonrefundable once the virtual product takes effect; support is handled at [email protected].

Platforms

ProcessOn runs on the web and has Android and iOS apps. There is no desktop app, so users who require a dedicated Windows, macOS, or Linux client should look elsewhere. Cloud synchronization is the advantage of its browser-and-mobile approach, particularly for people moving between devices.

Who it's for

Choose ProcessOn for collaborative process mapping, software and network diagrams, organizational planning, or mind mapping when broad import/export support matters. The free plan fits short-lived personal projects and small reviews. Teams with more than three collaborators, or anyone maintaining more than nine personal files, should budget for an edition with unlimited allowances. It is a weaker fit for desktop-first workflows or buyers who need a clearly published subscription price before committing.

Pros and cons

• Pro: Extensive diagram-type coverage serves business, software, and planning use cases in one workspace.
• Pro: Real-time collaboration, link sharing, synchronized cloud storage, and historical versions support distributed teams.
• Pro: Visio, XMind, Markdown, Mermaid, Excel, and POS imports plus numerous export formats reduce conversion friction.
• Con: The free plan caps personal files at 9 and collaborators at 3, limiting sustained team use.
• Con: Free users receive only partial download formats and small customization allowances.
• Con: Personal and Lifetime pricing is custom rather than stated, and effective membership fees are nonrefundable.
• Con: No desktop app is offered.

Alternatives

For a genuinely free, open-source option with no sign-up requirement, choose draw.io; it runs across web, Windows, macOS, Linux, iOS, and Android. EdrawMax is worth considering if its freemium plan, 500 AI tokens, 100M cloud storage, and broader desktop platform coverage match your needs.

Lucidchart suits readers who prefer a freemium collaboration tool with a free allowance of three editable documents, 60 shapes per document, and 100 basic templates. Grapholite is an alternative for buyers seeking a perpetual personal license at $49.99 once, with one user, two PCs, and a three-year upgrade guarantee.

OmniGraffle is a paid, Apple-focused choice for macOS and iOS. Cacoo offers a free plan with unlimited users, six sheets, PNG exports, real-time editing, and in-app video chat. Sparx Enterprise Architect is an alternative UML modeling environment. Structurizr is another option for architecture-focused teams.

Verdict

ProcessOn is a strong choice for users who want one synchronized workspace for many diagram types, collaborative editing, version history, and extensive import and export formats. Look elsewhere if you need a desktop application, a permanently free plan without file and collaborator caps, or transparent paid pricing before purchase.
