Read this page as one judge. Each weighs the same scores by what they care about.

The Skeptic

Weighted verdict

Assumes the marketing is lying until the evidence says otherwise. Hunts lock-in, dark patterns, hidden cost and dead changelogs. Exists to keep the rest of the panel honest.

Same scores as the panel view — this lens weights them the way this judge cares.

Scored by The Skeptic

Collaboration depth

How this is scored

How much real multi-person project work the tool carries: shared planning, assignments, dependencies, workload, comments, guest access.

0 — A personal task list; a second user has no defined place in it.

3 — Tasks can be shared and assigned, but planning stays per-person — no shared timeline, workload or dependency view.

5 — Solid shared projects with assignments, comments and at least one team-level planning view; gaps appear in cross-project or capacity planning.

8 — Team-level planning is first-class: cross-project views, workload/capacity, dependencies, guest or client access with sane permissions.

10 — Handles the full span from two freelancers to a structured department in one model — planning, capacity, permissions and client involvement all without workarounds.

Report an error

The Skeptic

Assignments, comments, four dependency types with automatic planning and a critical path, plus cross-project portfolios from Premium are all documented, and the External role comes free from Premium with permission boundaries spelled out (local links do not extend access). We found no public information on a workload or capacity view — the member perspective only counts tasks by status — so I stop short of the top. 6 7 8 9 15

Reporting

How this is scored

Whether the tool can answer questions about the work: progress, time, budgets, utilization — and export the answer.

0 — No reporting beyond looking at the board.

3 — Fixed per-project status views only; nothing aggregates across projects and nothing exports cleanly.

5 — Useful standard reports (progress, tracked time) with basic filters and CSV export, but limited customization and no budget/utilization depth.

8 — Configurable cross-project reporting incl. time, budgets and utilization, with dashboards and reliable exports.

10 — Reporting is a product in itself: custom report builder, scheduled delivery, API access to every metric the UI shows.

Report an error

The Skeptic

Reports exist, group by status, custom fields and rooms, are printable and exportable, and the dashboard aggregates task counts per member with cross-project portfolios to monitor multiple projects. We found no public information on time tracking, budgets or utilization, and no export format is ever named, which keeps this below the configurable-reporting standard. 3 7 8 9

Integrations

How this is scored

How well the tool connects to the rest of the stack: native integrations, calendar/comms hooks, API and webhooks, import/export paths.

0 — A closed box — no API, no integrations, CSV out if anything.

3 — A handful of marquee integrations, no public API or an API that covers a fraction of the product.

5 — The common set (calendar, Slack/Teams, file storage) plus a documented public API; automation platforms partially covered.

8 — Broad native catalogue, well-documented API and webhooks, first-class automation-platform support and real import paths from competitors.

10 — Ecosystem-grade: everything in 8 plus the tool is itself extensible (apps/plugins, AI/MCP surfaces) and exit via API export is complete.

Report an error

The Skeptic

There is a documented API with JWT-secured incoming webhooks across several content types, and a video shows importing boards from other tools via Excel. But we found no public information on native calendar, Slack/Teams or file-storage integrations, the API is capped at one request per second, excludes end-to-end encrypted rooms, gates task operations behind Premium and pushes user/room management to Enterprise — Zapier and IFTTT only appear reachable through hand-rolled webhooks. 10 11 13

Onboarding effort

How this is scored

Time and friction from signup to first real value for a small team, without paid services.

0 — No self-serve path — onboarding starts with a sales call and an implementation project.

3 — Self-serve exists but the first project requires configuration a newcomer cannot judge yet (workflows, custom fields, permissions) before anything works.

5 — A team gets a first project running within a day; trial requires payment details or key steps live behind docs.

8 — Signup to working project inside an hour: guided setup, sensible defaults, templates, trial without payment details.

10 — Minutes to value even for non-tool-people, importers pull existing work in, and the tool teaches its own advanced features as the team grows into them.

Report an error

The Skeptic

Self-serve signup with a 14-day trial, "No credit card required" and "No minimum contract period" is published, and video tutorials cover an Excel import for pulling existing boards in. We found no public information on guided setup or templates, so I cannot credit the fast lane to the top. 2 12 13 14

European sovereignty

How this is scored

Where the company and the data actually sit: legal entity, ownership control, data residency, and subprocessor exposure to non-EU jurisdictions.

0 — Non-European vendor, data on US infrastructure under US law, no DPA worth the name.

3 — DPA and GDPR language present, but hosting defaults to the US or ownership sits outside Europe — compliance paperwork over substance.

5 — EU data residency is available and contractually fixed, but the vendor or its controlling owner is non-European, or core subprocessors put data within CLOUD Act reach.

8 — European company under European control with EU-resident data and a public DPA; remaining exposure is limited to identifiable subprocessors (e.g. a US hyperscaler's EU region) and is documented.

10 — European company, European control, EU-only data residency on European infrastructure, subprocessor list free of extraterritorial reach — verifiable, not asserted.

Report an error

The Skeptic

A Munich GmbH under exclusive German and EU jurisdiction, EU-resident data with a click-through DPA, a named data protection officer, BSI C5 and ISO 27001 claims, and a published subprocessor list of German and Estonian firms make the core substance real. The privacy policy nonetheless concedes processing in countries the EU deems safe and, under the Data Privacy Framework, in the USA — and the administrator-activated Giphy integration sits in New York — while we found no public information establishing who ultimately controls the company. 3 4 5

Support & documentation

How this is scored

Whether a stuck user gets unstuck: docs quality, support channels and their availability per plan, and the health of the learning surface.

0 — No docs beyond marketing pages; support is a contact form that may answer.

3 — Docs exist but are thin or stale; support on entry plans is effectively email-only with slow turnaround.

5 — Searchable help center covering the core product; chat or email support on all plans with reasonable response times.

8 — Deep, current docs incl. onboarding guides and templates; fast chat support not gated to top tiers; visible changelog.

10 — Docs, academy, community and support so good they are a reason to buy; SLAs published, support quality independent of plan.

Report an error

The Skeptic

Live chat, a support channel, email and phone are published, screen-sharing sessions are offered over Stackfield, TeamViewer or Webex, and the help center runs deep across Gantt, email integration, the dashboard and the developer API. We found no public information on a visible changelog, published support response times, or which plans get which channel — the service level agreement on offer covers platform availability, not support. 3 10 14

Pricing transparency

How this is scored

Can a buyer determine the real, payable cost of the tool for their team before talking to anyone?

0 — No public pricing at all — every number sits behind "contact sales".

3 — Some tiers are public, but a deciding factor (seat minimums, mandatory add-ons, billing-period surcharge, tax treatment) only surfaces at checkout or in fine print.

5 — Self-serve tiers are publicly priced and the billing-period difference is stated, but the headline number still needs qualifying — e.g. annual-only headline, taxes excluded without saying so, or an opaque enterprise tier doing real work.

8 — Every self-serve tier is fully priced with billing periods and tax treatment plain on the page; only genuinely custom enterprise work lacks a number.

10 — Every tier including enterprise has a public price or published price formula, and the headline number is the number on the invoice.

Report an error

The Skeptic

Every tier carries an exact figure — "€ 9", "€ 14", "€ 18", "€ 28 per User and Month (when paid yearly)" — with priced add-ons (AI at "€ 3,90", OFFICE at "€ 2,40"), VAT treatment stated as quoted net and exclusive of VAT, and Starter's room and user caps shown up front. But every headline number is the yearly-billed one: a monthly option is implied by "Yearly (SAVE 17 %)" without its price being published, and the on-premise offering appears with no number at all. 2
