Nintex Automation K2

skybow vs K2 (2026)

K2 (now Nintex Automation K2) needs developers and a six-figure budget. skybow runs inside the SharePoint you already have.

Summary

K2 (formerly K2 blackpearl / K2 Five, acquired by Nintex in 2020) is an enterprise business process platform built for deep, code-level integration across many systems. It typically needs .NET/SQL developers, runs as its own infrastructure alongside SharePoint, and carries quote-based pricing that commonly starts at $30,000–$100,000+ for a mid-size deployment plus 18–22% annual maintenance. skybow runs natively inside SharePoint with one flat per-user license and a no-code builder — typically live in days to a few weeks. Choose skybow for SharePoint-centric forms and workflow; choose K2 if you need deep orchestration across many enterprise systems and have the developers and budget for it.

Choose skybow if

  • You want business users and IT generalists to build forms and workflows — no .NET, SQL or K2 certification required.
  • You want transparent, predictable per-user licensing instead of a quote-based enterprise contract.
  • Your processes live mainly on SharePoint lists and libraries, not spread across many enterprise systems.
  • You want to go live in days to a few weeks, not a multi-month implementation.
  • You run SharePoint Server SE/2019, hybrid or Online.

Choose K2 if

  • You need deep, code-level integration across many enterprise systems — ERP, CRM, custom databases, legacy line-of-business apps.
  • You have an in-house or partner team with .NET, SQL and K2 development skills.
  • You're standardising enterprise-wide on Nintex's automation portfolio.
  • A multi-month implementation and enterprise budget aren't blockers.

Deep dive

A closer look at the differences

Do I need developers to build with K2?

In practice, usually yes. K2 markets visual, wizard-based design tools, but real-world implementations commonly need dedicated .NET, SQL and K2-certified developers — these skills routinely show up as core requirements in K2 developer job postings. skybow's forms and automation builder is designed for business users and IT generalists: no code, no SQL, no separate certification track to build and maintain solutions.

Does K2 run inside SharePoint like skybow?

No. K2 is a separate platform that integrates with SharePoint — among many other enterprise systems — rather than running natively inside it. That breadth is genuinely useful for orchestrating processes across many systems, but it means a separate environment, its own security model, and its own infrastructure to run and maintain. skybow runs entirely inside the SharePoint you already have — no separate server, database or login.

How fast can I go live compared to K2?

K2 implementations for mid-to-large deployments commonly run for months, reflecting the .NET/SQL development, infrastructure setup and integration work involved. skybow solutions are typically built and deployed in days to a few weeks, since forms, workflow logic and deployment all live inside SharePoint's existing structure — no separate platform to stand up first.

Where the alternative is strong

K2 (Nintex Automation K2) is a genuinely capable enterprise platform for organisations that need to orchestrate complex processes across many systems beyond SharePoint — ERP, CRM, custom databases, legacy line-of-business applications. If you have the development resources and budget for a multi-system integration platform, and your automation needs reach well beyond SharePoint, K2 is a serious enterprise option. For SharePoint-centric workflow and forms, it is usually more platform — and more development effort — than the job requires.

Pricing and licensing

skybow uses one transparent, flat per-user license that includes forms, automation actions and deployment — no metering per action, flow or connector. K2 uses quote-based enterprise pricing that Nintex does not publish; industry estimates put initial licensing for a mid-size deployment at $30,000–$100,000 or more, plus 18–22% annual maintenance — before the .NET/SQL development work most implementations require. For SharePoint-centric workflow and forms, skybow is typically a fraction of a comparable K2 enterprise contract.

Frequently asked questions

What is K2 (Nintex Automation K2)?

K2 was originally an independent business process automation vendor (K2 blackpearl, later K2 Five). Nintex acquired K2 in 2020, and it is now sold as Nintex Automation K2 — the enterprise, on-premises-capable path Nintex recommends for customers who cannot or do not want to move to Nintex Automation Cloud.

Do I need developers to build with K2?

In practice, usually yes. K2 markets visual, wizard-based design tools, but real-world implementations commonly need dedicated .NET, SQL and K2-certified developers — these skills routinely show up as requirements in K2 developer job postings. skybow's forms and automation builder is built for business users and IT generalists, with no code and no separate certification track.

Is K2 cheaper than skybow?

Usually not. K2 uses quote-based enterprise pricing that Nintex does not publish; mid-size deployments commonly run $30,000–$100,000 or more in initial licensing, plus 18–22% annual maintenance — before implementation costs. skybow uses one flat, transparent per-user license that includes every feature you build.

Does K2 run inside SharePoint like skybow?

No. K2 is a separate platform that integrates with SharePoint — among many other enterprise systems — rather than running natively inside it. That breadth is genuinely useful for cross-system orchestration, but it means a separate environment, its own security model, and its own infrastructure to run and maintain. skybow runs entirely inside the SharePoint you already have.

Is skybow a good K2 alternative for SharePoint?

Yes, for SharePoint-centric forms and workflow needs. skybow delivers no-code forms, automation and Dossiers directly on your SharePoint lists, with one flat per-user license and no separate infrastructure — typically live in days to a few weeks rather than the multi-month implementations common with K2.

When is K2 the better choice over skybow?

Choose K2 when your automation needs to reach deep into many enterprise systems beyond SharePoint — ERP, CRM, custom databases, legacy line-of-business applications — and you have the development resources and budget for a multi-system integration platform. For SharePoint-centric workflow and forms, it is usually more platform, more development effort, and more cost than the job requires.
