draw.io, also known as diagrams.net, is a free, open-source diagram editor for flowcharts, network diagrams, UML, BPMN, org charts, and whiteboards. It runs in the browser with no account, as offline desktop apps, or self-hosted, and saves diagrams to storage the user chooses instead of vendor servers. It suits security-conscious teams, Confluence and Jira users, and anyone who wants a full-featured Visio-class editor without seat licenses. Its Apache 2.0 codebase has tens of thousands of stars and a public history going back to 2005-era file compatibility.[1][2]
Quick verdict
Security-conscious teams and Confluence or Jira shops will get the most from draw.io. Its free Apache 2.0 editor, offline desktop apps, user-chosen storage, and zero-egress Forge option give regulated teams real data control at no seat cost. Teams with very large diagrams or self-hosted live co-editing needs should verify those limits first, since reviewers note heavy-diagram clunkiness and the self-hosted build lacks real-time collaboration. If you need a free, precise, data-controlled diagrammer, choose draw.io; if you need whiteboard-first workshops, choose Miro or Excalidraw instead.[1][2][3]
Key features
Full editor in the browser, no account Flowcharts, org charts, floor plans, network diagrams, and whiteboards all open in a complete web editor that requires no signup, no trial, and no paywall before the first diagram.[1]
Offline desktop apps for three platforms Free desktop apps for Windows, macOS, and Linux run the same editor offline, and the desktop app is isolated from the internet so diagrams never leave the machine during editing.[1][2]
Real-time collaboration with shared cursors Hosted editing supports real-time collaboration with shared cursors on diagrams and whiteboards. Boundary: the self-hosted open-source build states it does not support real-time collaborative editing in that version, so teams choosing self-hosting should verify the current collaboration story before relying on it.[1][2]
Shape libraries for UML, BPMN, and cloud architecture Built-in libraries and templates cover UML, BPMN, AWS and Azure architecture, entity-relationship, network, and electrical diagrams, so standard notations work without hunting for third-party stencils.[1]
Diagrams live in storage you choose Saves go to Google Drive, OneDrive, SharePoint, GitHub, GitLab, Notion, Dropbox, or local files at the user's choice; the vendor states diagram data stays out of its own servers.[1]
SVG, PNG, and PDF export plus embeds Diagrams export to SVG, PNG, and PDF, and interactive diagrams can be embedded in any web page, which keeps published docs live without re-exporting screenshots.[1]
Native Confluence and Jira apps First-party Confluence and Jira integrations, including a zero-egress Forge option built with Atlassian, let regulated teams diagram inside their existing wiki and tracker with no diagram data leaving the host.[1][2]
No-tracking security posture The site uses no tracking, the desktop app runs internet-isolated, and only PDF or raster export conversion briefly processes diagram data before deleting it, which is the concrete basis for its regulated-environment claims.[1]
Who will love it
Because the core editor, desktop apps, and self-hosted builds are free under Apache 2.0 with no seats or trials, cost approval never gates adoption. A team can standardize on it for every contributor, including contractors, without license true-ups.[1][2]
Native Confluence and Jira apps plus Drive, OneDrive, SharePoint, and GitHub storage mean diagrams live where the team's docs and code already are. Documentation stays beside the system it describes instead of in a separate tool account.[1][2]
Reviewers ranging from teachers to network engineers report productive use with no prior design experience, and the offline desktop app covers air-gapped or travel work. Teams that need a real editor rather than a sketchpad, with data control, get both at once.[1][2]
Who should avoid it
A verified reviewer reported that draw.io can feel clunky with large diagrams and that the interface looks dated, while still getting the job done. Teams maintaining very large or dense diagrams should trial their heaviest real file before committing, rather than assuming infinite-canvas smoothness.[1]
The self-hosted open-source build explicitly states it does not support real-time collaborative editing in that version. Distributed teams that need live co-editing on their own infrastructure should treat this as a current limitation and verify the latest release notes.[1]
The Confluence and Jira integrations are separate Marketplace apps outside the free core, so Atlassian-centered teams face a second procurement with its own per-user tiers. Budget the integration, not just the editor, when costing a Confluence rollout.[1][2]
What the reports suggest
Inspected sample of original user reports: verified G2 reviews for draw.io (5.0 aggregate shown on-page from a small reviewer count), with both 5-star ease-of-use reports and a 4-star report noting heavy-diagram friction.
1 cited community source. Small inspected sample: one community review page with a handful of visible verified reviews, all from 2023 or undated in the excerpt shown. No Reddit originals were accessible in this run, so forum sentiment is a documented gap rather than a finding.
The inspected reports converge on ease of entry: multiple verified reviewers describe draw.io as simple to start with and easy to use with no design background, and praise goal-achievement over feature breadth.[1]
The one dissenting note concerns scale rather than learnability: heavy diagrams, not beginners, are where friction appears. That pattern suggests piloting with the team's largest real diagram is more informative than piloting with a new user.[1][2]
Alternatives and compatibility
Migration paths are documented, not just marketing: the editor imports .vsdx, Gliffy, and Lucidchart files, and the vendor publishes a Gliffy migration guide. Teams leaving a paid incumbent can bring existing diagram libraries rather than redrawing them.[1]
Against Excalidraw, choose draw.io when the job needs structured notations, offline desktop use, or Confluence depth; choose Excalidraw when the job is fast hand-drawn-style whiteboarding with minimal learning curve.[1][2]
Against Miro, choose draw.io when diagrams must live in team-controlled storage with no per-seat cost; choose Miro when the priority is facilitated multi-user workshops with managed onboarding rather than precise technical diagrams.[1][2]

Questions worth asking
What is the best draw.io alternative for non-technical users?
A whiteboard-first tool such as Miro, one of draw.io's listed alternatives, is the safer pick for a purely non-technical team that wants guided onboarding and informal sketching. draw.io suits non-technical users only when someone comfortable with structured shape palettes sets up the templates first; reviewers call it easy to use, but its power lies in deliberate diagram construction, not freeform drawing.[1][2]
Is draw.io really no-code?
Mostly yes for diagram work: the editor is visual, needs no account, and reviewers report using it with no prior design experience. Code or admin skill enters only at the edges, such as self-hosting the app, wiring Confluence or Jira integrations, or embedding diagrams programmatically.[1]
How much does draw.io cost per month?
The core product costs nothing per month: the web editor, offline desktop apps, and self-hosted builds are free under Apache 2.0 with no account or seat tiers. The Confluence and Jira apps are licensed separately through the Atlassian Marketplace rather than bundled with the free core; current per-user tiers were not verifiable on the official pages in this run, so check the Marketplace listing before budgeting. Prices checked October 9, 2026.[1][2][3]
Can you self-host draw.io?
Yes. The editor ships as offline desktop apps and as a self-hostable build under Apache 2.0, runnable locally with a single docker command, and diagram data stays in storage the operator chooses rather than on vendor servers. Regulated teams can additionally use the zero-egress Forge option for Confluence and Jira so no diagram data leaves the host.[1][2]
