The short version

  • Docker starts at $11/mo; Proto.io prices on request.
  • Only Docker lists container runtime; only Proto.io lists event and condition system.
  • Where Docker falls short: shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation.
  • Prices and features on this page were last checked on 13 November 2026.

Proto.io

  • Running usability tests where the prototype must respond to real input rather than replay a fixed click pathnot Docker
  • Demonstrating a form-heavy or data-driven flow to stakeholders before any code existsnot Docker
  • Testing a mobile interaction on the physical device it is designed for, with correct gesture behaviournot Docker
  • Validating a concept for a client who needs to feel the product, not watch a video of itnot Docker

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

Proto.io

  • Prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given
  • Design is done elsewhere and interaction is rebuilt here, so every change to the visual design has to be reapplied by hand and the two artefacts drift apart
  • The event and condition model is layer based, so a genuinely complex flow becomes a large tree of triggers that nobody but its author can audit
  • Editor seats are priced individually and viewer access is limited on lower plans, so opening review to a wide stakeholder group pushes you up a tier for people who never edit anything
  • The market standardised on Figma, so hiring people who already know Proto.io is progressively harder and every new researcher is a training cost

Questions people ask

Is Docker or Proto.io better?
Neither clearly leads. Docker starts at Free and Proto.io at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Docker or Proto.io?
Docker has a free tier; the other does not. Paid plans start at Free for Docker and On request for Proto.io.
Does Docker or Proto.io run on more platforms?
Docker runs on Linux, macOS, Windows. Proto.io runs on Web, iOS, Android.
Can I use Docker for free?
Yes. Docker has a free tier, so you can try it without paying. Proto.io starts at On request.
What is Docker best used for?
Docker is most often used for application containerization, microservices, ci/cd pipelines, development environments. Of those, application containerization and microservices are not what Proto.io is typically brought in for.
What can Docker do that Proto.io cannot?
Docker covers Container runtime, Docker Desktop, Docker Hub, Docker Compose. Proto.io covers Event and condition system, Timeline animation, Device preview, Component library.

Answered from the vendors’ own pages

Docker: What is Docker pricing?

Docker offers a freemium model with Docker Personal free, Docker Pro at $11/user/month, Docker Team at $16/user/month, and Docker Business at $24/user/month. Each tier includes Docker Desktop, Docker Hub, and Docker Scout with different usage limits.

Source
Proto.io: Can it replace Figma?

No. It has no design system or file-handoff role. It sits alongside Figma for the prototypes Figma cannot express.

Docker: Can I use Docker in production?

Yes. Docker is used extensively in production environments. However, for container orchestration at scale, Kubernetes is typically paired with Docker to automate deployment, scaling, and management across clusters.

Source
Proto.io: What happens to prototypes if we stop paying?

They stop being accessible unless you have exported them, and offline export is restricted to higher plans, so plan archiving before you cancel.

Docker: What are the main security concerns with Docker?

Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.

Source
Proto.io: Is it worth learning now that InVision has gone?

If your work is usability research on conditional flows, yes. If you need click-through demos of static screens, Figma already does that at no extra cost.

Docker: Does Docker integrate with CI/CD systems?

Yes. Docker integrates with Jenkins, GitHub, and other CI/CD systems. The typical workflow involves GitHub repositories triggering automated builds in Jenkins, which prepare Dockerfiles and push images to Docker Hub for deployment.
