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

The Team Lead

Weighted verdict

Runs a distributed team and needs the tool people actually open. Wants threads that stay readable, search that finds last spring's decision, and channels that can be tidied without losing history. Unmoved by feature lists that do not survive a busy Tuesday.

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

Scored by The Team Lead

Channels, threads & search

How this is scored

The daily surface: channel model, threading, mentions, files, and whether search can find a decision made eighteen months ago.

0 — Flat group chats with no threads; search covers recent messages only, and history is capped.

3 — Channels and direct messages with basic search, but threading is awkward or absent and file handling is a plain attachment list.

5 — Public and private channels, real threads, mentions and reactions, file sharing with previews, and full-text search across the whole history.

8 — Cross-organisation or guest channels with clear boundaries, message editing history, pinned and saved items, search with filters by channel, person and date, and a documented history limit or none at all.

10 — The archive is a working knowledge base: search that ranks well across years, threads that stay readable, channel lifecycle management (archive, rename, merge) without losing history, and export of a conversation in a form a human can read.

Report an error

The Team Lead

Real threads, reactions, polls, attachments and explicitly unlimited history are confirmed, and federation gives cross-organisation rooms — but the evidence is completely silent on search, message-edit history, pins and channel lifecycle. The anchor-5 requirement of full-text search across the whole history is unevidenced, and my team lives on finding last spring's decision, so I interpolate between 3 and 5. 1 2

Encryption & access control

How this is scored

What is encrypted and against whom, plus who can reach which room. Judged on documented mechanism, since "encrypted" in this category usually means the vendor holds the keys.

0 — Transport encryption only, undocumented; no role model beyond admin, guests indistinguishable from members.

3 — TLS and encryption at rest with vendor-held keys, basic roles, and guest access that mostly works.

5 — The above plus configurable roles per channel, SSO, guest accounts with scoped visibility, and a clear statement of what the vendor can read.

8 — Optional end-to-end encryption for direct messages or private rooms with the trade-offs named, device verification, session management an admin can revoke, and documented key handling.

10 — End-to-end encryption as a first-class mode — documented or open cryptography, cross-device key management that ordinary users survive, identity verification, and the vendor stating plainly what it cannot decrypt.

Report an error

The Team Lead

The entire platform is end-to-end encrypted by default with non-encrypted rooms as the configurable exception, device verification via QR code or emoji string that ordinary users survive, and open-source Matrix underpinnings. The vendor states plainly that E2EE content is never accessed by its teams or shared externally — this is the anchor-10 package, not a bolt-on. 2 3

Report an error

Retention, discovery & co-determination

How this is scored

The archive as a legal object: retention policies, export for discovery, audit, and the monitoring features a works council will ask to have switched off.

0 — No retention policy, no export beyond a manual copy, no audit log, and presence or activity analytics that cannot be disabled.

3 — Manual export of some data and a global history limit, but no per-channel retention, no audit log and no admin control over analytics.

5 — Configurable retention per channel or workspace, admin export in a documented format, an audit log of administrative actions, and status or presence that a user can control.

8 — Legal-hold and eDiscovery export including edits and deletions, retention executed per policy and evidenced, full admin audit trail, and activity analytics switchable off organisation-wide.

10 — Built to pass a works agreement and a subpoena on the same day: granular retention with documented deletion, discovery export a lawyer can use, complete audit, and no individual-level productivity scoring anywhere in the product.

Report an error

The Team Lead

Rules-based retention for messages and media and in-room auditing capturing an official record for compliance are evidenced, and no user profiling plus opt-in internal Matomo analytics is genuinely good. But there's no legal hold, no eDiscovery export format, and the audit covers room discussion rather than administrative actions, so it sits between the 5 and 8 anchors. 2 3

Report an error

Deployment & data custody

How this is scored

Whether the customer can hold their own archive: self-hosting, private cloud, open source, federation, and what an exit actually looks like.

0 — Cloud-only, proprietary, with export limited to a partial archive.

3 — Cloud-only, but with a documented full export in an open-ish format.

5 — A private-cloud or dedicated-instance option, or a self-hosted edition that lags the cloud significantly; full export documented.

8 — A genuine self-hosted edition close to feature parity, or open-source core with a documented upgrade path, plus complete export including files and metadata.

10 — Custody is the customer's: open-source or source-available server, self-hosting supported as a first-class deployment, open protocol or federation, and a migration path in and out that the vendor documents rather than resists.

Report an error

The Team Lead

AGPL community edition, official helm charts for Kubernetes, S3 media repository, custom push gateway, and air-gapped deployment with no internet needed, on an open federated protocol with export explicitly positioned against vendor lock-in — custody is effectively the customer's. Docked one point because the free community homeserver is explicitly 'not for use in production environments', making the production-grade self-host path the paid edition. 1 2

Report an error

Integrations & extensibility

How this is scored

Bots, webhooks, app framework, identity — whether the chat becomes the place work is noticed, and whether that is buildable without a partner agreement.

0 — No API, no webhooks, no bots.

3 — Incoming webhooks and a handful of native integrations; no bot framework, no documented limits.

5 — Documented REST API, incoming and outgoing webhooks, slash commands, a bot account model, and SSO.

8 — A proper app framework with interactive components, event subscriptions with retries, SCIM provisioning, documented rate limits and a sandbox.

10 — A platform: versioned API with a deprecation policy, an app directory or plugin system with permissions a customer can audit, and integrations the vendor maintains rather than lists.

Report an error

The Team Lead

Named widgets (NeoBoard, OpenProject, Jira), LDAP/SCIM provisioning and OIDC SSO are real, and SCIM is an anchor-8 item. But the evidence evidences no documented REST API, webhooks, bot framework, rate limits or sandbox — my team can't build on what isn't documented. 1 2

European sovereignty

How this is scored

Where the archive and its metadata live, who the contracting entity is, which subprocessors touch it. Independently sourced by the sovereignty pipeline; scored here as this buyer weighs it.

0 — Non-EU vendor and contracting entity, hosting unstated or non-EU, subprocessors unnamed.

3 — EU data residency offered for message content while metadata, search indexes or support tooling remain non-EU, or the contracting entity sits outside the EU.

5 — EU hosting as standard and an EU contracting entity, but parts of the chain — notifications, AI features, analytics — are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, full subprocessor list published, any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting and every subprocessor European, certification published, and a self-hosted option that removes the question.

Report an error

The Team Lead

Hosting is named EU infrastructure (AWS Amsterdam/Stockholm, with customer region choice) and the subprocessor list is published — but the contracting entity is Element Creations Ltd in London under the UK ICO, outside the EU, and named subprocessors like Cloudflare, Twilio and Salesforce come with no stated jurisdiction or legal basis. Self-hosting and air-gap options let me remove the question entirely, which keeps this at 5 rather than the UK-entity baseline of 3. 2 3

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the annual invoice for their headcount — including the retention, compliance and guest features they actually need — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A per-user headline exists, but the tier where retention control, SSO or compliance export begins is unstated.

5 — Per-user prices public with billing period stated, but at least one commonly needed capability (unlimited history, SSO, eDiscovery) sits in an unpriced enterprise tier.

8 — Every tier priced publicly with per-user maths, history and storage limits, feature boundaries, minimum term and VAT treatment stated; self-hosted licensing priced too where offered.

10 — Complete price computability: annual invoice derivable for a given headcount and deployment choice, including guest users, storage and any per-instance licence.

Report an error

The Team Lead

The only public number is zero: the AGPL Community edition is free, but Element Server Suite Pro is 'Priced per seat/month' with no figure and a 'Talk to an expert' prompt, and even the server-limit terms reference unspecified 'price minimums'. No annual invoice is computable from these pages, which lands just above the all-sales-conversation anchor. 2
