Alternatives

The best Slickplan alternatives, honestly compared.

Slickplan is the elder statesman of sitemap tools — polished diagrams, a content module, enterprise trimmings. People usually go looking for alternatives for one of three reasons: the price climbs with projects and seats, the content module feels bolted onto the diagrams rather than central, or they need real client sign-off rather than comment-style feedback.

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 Slickplan.

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).

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).

Blocky vs Octopus.do

FlowMapp

A UX planning suite: sitemaps, user flows, personas and customer journey maps together.

Strongest for: UX-led projects where the sitemap is one artefact among several — flows, personas and journeys in the same workspace.
Worth knowing: Content planning is shallow next to dedicated tools, and there's no client sign-off workflow — it's a UX team's tool, not a content approval pipeline.

Published plans start around $9–15/month and scale with projects (checked July 2026).

Blocky vs FlowMapp

Relume

AI sitemap and wireframe generation that lands as components in Figma and Webflow.

Strongest for: Webflow/Figma teams who want AI to propose structure and produce designer-ready wireframes with a huge component library.
Worth knowing: AI-generated placeholder copy still needs deciding, writing and approving somewhere — Relume accelerates design, not content agreement. Per-seat pricing adds up for bigger teams.

Published pricing is per seat, from roughly $32–40/month per person (checked July 2026).

Blocky vs Relume

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.
