Design systems / Design workspace
OpenDesign
Use a shared design system while iterating on working prototypes.
Understand the resource
What it is.
OpenDesign describes a collaborative workspace where coding agents create HTML prototypes, teams comment and work can be exported. Its current product includes local agents and cloud/team options, so the chosen workflow determines where project data travels.
When it is useful
You want designers and engineers to review the same interactive prototype.
A proposed application
Put it to work.
This example illustrates a possible use. The proposed workflow and expected result are separate from the bounded checks recorded below.
Try this
Build a synthetic settings flow with an approved system, gather comments, and inspect the revised HTML before handoff.
Result to aim for
A prototype plus traceable feedback and implementation files.
Before you start
What you need.
- A supported environment and an agent or cloud account; provider and sharing choices need explicit review.
The practical boundaries
What to watch for.
- Local-first does not guarantee every path stays local: model providers, cloud workspaces and share links change the data boundary.
- No installation, provider connection or export workflow was tested; inspect repository permissions and dependencies before use.
Review record
What we could establish.
- Public primary documentation reviewed. See the account-free evaluation for executed checks and remaining workflow limits.
- Current primary documentation includes cloud and team-sharing options; do not assume all processing is local.
The source-review notes describe documentation and identity. The account-free evaluation below records exactly which public interaction or local fixture was checked, what happened, and what remains untested.
Check current access, terms, licensing and data handling before using a resource with your own material.
Runtime and security evaluation
What the evaluation covers.
The Showcase opened an account-free collection of website, app, slide and graphic examples; 27 page images decoded during the visit.
Methods: Public HTTP response · Public browser sample. A completed check covers the stated sample; it is not a safety certification.
- Target
- https://open-design.ai/
- Version or capture
- Unversioned public page observed on 2026-10-19
- Integrity scope
- sha256:e23709155a662f024b0c20993b98d502e8895368f0d5878f172130261d92345f — initial HTTP 200 response body only; not whole-application integrity.
Test conditions
- Chromium 155.0.8059.82, 1365×900 desktop viewport.
- Separate fresh, ephemeral browser contexts for entry and interaction; no owner profile, credentials or stored session.
- Only GET/HEAD network requests allowed; forms, downloads, WebSockets and service workers blocked. Some analytics endpoints also blocked.
- Short bounded waits; no mobile, assistive-technology, cross-browser or performance certification.
Individual checks and observations
Public HTTP response
passPublic HTTP response: Anonymous GET with redirects followed, response-body SHA-256 and selected security-header summaries; no cookies retained.
Observed: The standalone client received 200 at https://open-design.ai/. This establishes response delivery only.
Fresh browser entry
passPublic browser sample: Open the catalog URL in a new anonymous Chromium context with read-only network guards and no inherited profile.
Observed: The document returned 200 and identified itself as “OpenDesign — Best Open Source Claude Design Alternative”. 79 image elements were present; no account was used.
Observed public sample or navigation
passPublic browser sample: Follow the observed public sample link to https://open-design.ai/showcase/.
Observed: The destination returned 200; title: “AI Design Examples: Websites, Apps, Slides & Graphics | OpenDesign”. 27 page image elements had decoded during the bounded wait. This count is not a catalog size or performance benchmark.
Security findings and boundaries
Passive inspection of the initial public document’s response headers and anonymous browser request hostnames, with read-only guards. No source exploitation, account access, dependency audit or private data.
Observed · info
Public response protections
The initial browser page used HTTPS. No HSTS response header was observed. No enforcing Content-Security-Policy response header was observed. This records the sampled response only; meta policies, backend authorization and exploit resistance were not assessed.
Observed · info
Request surface in the anonymous visit
OpenDesign attempted requests to 5 additional hosts, including us-assets.i.posthog.com, www.googletagmanager.com, api.github.com, static.cloudflareinsights.com. Host counts include requests stopped by the test guard; they do not establish what data a service retained.
Practical advice · caution
Before using this reference
The showcase is useful for comparing output styles. It does not establish which local, cloud or model-provider path produced a particular example.
Practical caveats
- The showcase is useful for comparing output styles. It does not establish which local, cloud or model-provider path produced a particular example.
- Local-first does not guarantee every path stays local: model providers, cloud workspaces and share links change the data boundary.
What remains untested
- No workspace or provider connection was created, no agent was run and no collaboration or export flow was exercised.
- Results describe the observed public pages and a bounded action, not the entire product or the referenced designs.
Security limits
- No authentication, authorization, tenant separation, data retention or backend handling was tested.
- Header presence or absence is a sampled configuration observation, not a security certification or an exploit finding.
- 9 blocked-request records were retained across entry and interaction checks. Guards may alter normal page behavior; the logs do not represent unrestricted traffic.
