Alternatives

The best Relume alternatives, honestly compared.

Relume is superb at what it actually does: AI-generated sitemaps and wireframes that land as components in Figma and Webflow. People go looking for alternatives when the per-seat pricing bites, when they're not on the Webflow/Figma stack, or when they realise AI placeholder copy still leaves the hard part — deciding and approving the real words — completely unsolved.

Full disclosure: Blocky is our product and it’s first on this list — so every entry, ours included, says what the tool is genuinely strongest at and where it falls short. Prefer a feature-by-feature view? Blocky vs Relume.

Blocky

Sitemaps, wireframe content and client sign-off in one place — decide what the website says before anyone designs it.

Strongest for: Agencies and freelancers who lose weeks to content collection and want approval that sticks: structure, words, stages, owners and per-section client sign-off in a single tool, exported as Markdown/JSON for designers and AI.
Worth knowing: It's ours, so read this list knowing that — and it's deliberately not a diagramming suite or a visual design tool. If you need user-flow diagrams or high-fidelity mockups, pair it with one of the tools below.

Free for your first project with unlimited seats; Studio at £19/month flat (checked July 2026).

Slickplan

The veteran sitemap planner — polished diagrams, content planning, big-org features.

Strongest for: Presentation-ready sitemap diagrams, diagramming beyond websites (user flows, decision trees), and enterprise needs like SSO.
Worth knowing: Content and structure live in separate modules, and approval is lightweight feedback rather than recorded per-section sign-off.

Published plans start around $9–12/month for a single project and rise with projects and users (checked July 2026).

Blocky vs Slickplan

Octopus.do

The fastest visual sitemap builder — lo-fi wireframe blocks sketched straight onto the tree.

Strongest for: Speed. Sketching a site's shape live on a discovery call, with instant lo-fi blocks and a genuinely pleasant editor.
Worth knowing: The words are labels on blocks, not managed content — no stages, owners, or client approval; once real copy matters you've outgrown it.

Published plans run roughly $8–15/month (checked July 2026).

Miro / FigJam

Freeform whiteboards — sticky-note sitemaps and workshop energy, zero structure.

Strongest for: Live workshops. Nothing beats a whiteboard for the messy first hour of "what even is this website?" with a room full of stakeholders.
Worth knowing: A photo of sticky notes is not a plan: no tree, no content fields, no statuses, no approvals — everything must be rebuilt in a real tool afterwards.

Both have generous free tiers; paid team plans are per seat (checked July 2026).

Google Docs + a spreadsheet

The default stack: copy in Docs, sitemap in a sheet, approval in an email thread.

Strongest for: Zero cost, zero onboarding — every client already knows how to use it. Honestly fine for a five-page brochure site with one stakeholder.
Worth knowing: Nine documents, no single source of truth, and "looks great!" in an email approving a version nobody can find any more. The chaos scales with the project.

Free, in licence fees. Expensive, in chasing.

Whichever you pick, decide the words first.

The tool matters less than the sequence: structure, then words, then approval, then design. Our content-first process guide works with any of the tools above.
