Features

Everything your architecture docs need to stay current

Revision is one C4 model behind every view. Model it once, explore it, change it in Drafts, keep it trustworthy and share it with everyone who needs it.

Model

Model once. Every view updates.

Create each element once and place it in as many views as you need. Rename a container and every view updates.

Walk through a request, step by step

A flow tells one story through a view. Each step lights up on the diagram, so a new team member can follow a checkout from the shopper to the warehouse.

Search 580+ technologies across curated packs, choose the packs your workspace uses and add your own.

Explore

Answer impact questions before you change anything

See what depends on a system, who consumes its APIs and which relationships pass through it.

  • Dependency explorer

    Incoming and outgoing relationships for any element or API.

  • APIs and Via

    Systems, containers and components own APIs, with protocol and transport on every relationship.

  • Model maps

    Group the model by team, technology, deployment or your own attributes, and save filtered maps.

Model maps group every object by the question you are asking. Filter them and save the ones you come back to.

Design

Propose the next version. Merge it when it is ready.

Your first change to Current starts a Draft. By default everyone can read the Draft and its change list, and merging creates a new version.

Govern

Keep the model trustworthy as it grows

Give every element an owner team and a lifecycle, add the attributes your standards need, and let diagram checks show what is missing.

An owner and a lifecycle on every object

See who owns each system and whether it is planned, active, deprecated or retired, then filter and edit in bulk.

Share

Share with everyone. Readers are free.

Send a live link, embed a view in your docs portal or publish an image that updates with the model.

Discuss the architecture on the diagram

Every diagram has its own discussion. Mention people with @, reference objects with # and turn a row into a to-do.

Automate

Let agents and tools work on the model

AI agents read the model through MCP and propose changes in a Draft. Your tools keep component metadata current through the REST API.

Because the structure is built in, our documentation stays consistent without extra work. It’s faster to write, review, and understand.

Common questions

Comparing tools? See how Revision differs, side by side.

Is every feature on the Free plan?

Yes. The Free plan includes every cloud feature for one editor. Pro adds editors at €39 per editor per month, excluding VAT.

Do readers need a seat?

No. Readers and stakeholders are always free. Only editors need a seat.

Can AI agents change Current directly?

No. Agents connected through MCP propose their changes in a Draft, which your team reads before it is merged into Current.

Can we run Revision on our own servers?

Yes. Self-hosted Revision runs on your own infrastructure and works offline.
