The short version

Each has a real cost: Coder premium plan pricing is not published and requires contacting sales.; Outline the Business Source Licence is not an open source licence, so anyone planning to host Outline for clients, resell it or embed it in a commercial service is prohibited until the per-release change date passes, and this is regularly discovered only at legal review.
They diverge on capability: Coder covers Self-hosted workspaces, Outline covers Structured collections.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Coder

Premium plan pricing is not published and requires contacting sales.
Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs.
High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls.

Outline

The Business Source Licence is not an open source licence, so anyone planning to host Outline for clients, resell it or embed it in a commercial service is prohibited until the per-release change date passes, and this is regularly discovered only at legal review.
There is no local password authentication, so self-hosting requires an identity provider to be in place first, which turns a small internal wiki into a project with a dependency on Google, Okta, Entra or a Keycloak instance somebody has to run.
Self-hosting needs Postgres, Redis and S3-compatible object storage together, so the operational footprint is larger than the single database most internal wikis require.
The hosted plans offer no customer-selectable hosting region, so buyers with data residency obligations are pushed to self-hosting even when they would have paid to avoid running servers.
It is built for internal knowledge rather than public documentation, with no versioned documentation sets, no static output and limited public publishing, so it will not serve as a product documentation site.
Because it is a single-vendor project rather than a foundation-governed one, a future licence or pricing change applies to new releases and the only defence is staying on an older version.

Answered from the vendors’ own pages

Coder: Is there a free plan, and what are its limits?

Yes, the Community edition is free and includes unlimited workspaces, templates, and organization members with OpenID Connect SSO, aimed at hobbyists and small teams.

Source

Outline: Is Outline open source?

No, not in the OSI sense. It is source available under the Business Source Licence, which permits internal use and self-hosting but not offering it as a service to others, with each release converting to an open source licence after its change date.

Coder: What does Premium add over Community?

Premium adds ticket-based SLA support, multi-organization access controls, resource quotas, audit logging, AI governance, workspace proxies, high availability, and custom branding.

Source

Outline: Can I run it for free?

Yes, for your own organisation. Self-hosting carries no licence fee, only the cost of running Postgres, Redis, object storage and an identity provider.

Coder: How is Coder priced?

Community is free; Premium is priced per user annually, with the exact rate available by contacting Coder.

Source

Outline: Can I choose where the hosted version stores data?

No. The hosted plans do not offer a region choice, so residency requirements mean self-hosting.

Outline: Does it work for public product documentation?

Poorly. It has no versioned documentation sets or static site output, so it is best kept for internal knowledge.
