The best Slickplan alternatives, honestly compared.

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).

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).

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

Strongest for

UX-led projects where the sitemap is one artefact among several — flows, personas and experience maps 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).

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).

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).

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.
