The short version

  • Only Slab has a free tier, so it costs nothing to try first.
  • Each has a real cost: HelpDocs it is a knowledge base only, so a company still needs a separate ticketing or chat tool for any support that is not fully self-service; Slab it is built for internal knowledge, so public product documentation on a custom domain with versioning is outside what the product does.
  • They diverge on capability: HelpDocs covers Editor-only seat pricing, Slab covers Topics instead of folders.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

HelpDocs

  • It is a knowledge base only, so a company still needs a separate ticketing or chat tool for any support that is not fully self-service
  • Extra editor seats above a plan's included count cost $25 each per month, which adds up quickly for a growing content team on the Harvest tier
  • AI credits are capped per plan and reset monthly, so a heavy AI-drafting workflow can exhaust the allowance before the billing period ends
  • Moving from Sprout to Bloom to add editors is a large jump in absolute price, not a smooth per-seat increment, since each tier is a fixed bundle rather than pay-per-seat
  • There is no free tier, only a 14-day trial, so a small team wanting to test long-term usage patterns has a short evaluation window
  • Being editor-priced means it does not scale cost with help centre traffic or ticket deflection value delivered, so a high-traffic help site pays the same as a low-traffic one with the same editor count

Slab

  • It is built for internal knowledge, so public product documentation on a custom domain with versioning is outside what the product does.
  • There is no docs-as-code workflow, no git synchronisation and no markdown files on disk, so engineering-owned technical documentation ends up somewhere else anyway.
  • Hierarchy is shallow by design, and organisations that genuinely need deep nested structure find topics an awkward substitute rather than an improvement.
  • There is no offline mode, so a knowledge base that includes incident runbooks is unavailable during exactly the incident where the network is the problem.
  • Pricing is per user per month, so organisations where most staff only read a handbook twice a year still pay a seat for each of them.

Answered from the vendors’ own pages

HelpDocs: Are readers of the help centre charged for?

No, HelpDocs charges only for editors who log in to write and manage content; anonymous readers are unlimited and free.

Slab: Can I publish documentation publicly with Slab?

Posts can be shared by link, but it is not a product documentation platform. There is no custom domain publishing, versioning or API reference tooling.

HelpDocs: Is there a free plan?

No, HelpDocs offers a 14-day free trial rather than a permanent free tier.

Slab: What does the free plan actually cover?

Up to ten users with unlimited posts and core integrations. It is a real free tier rather than a trial, and it is enough for a small company handbook.

HelpDocs: Does HelpDocs include ticketing or live chat?

No, it is a knowledge base and help centre product only; it integrates with tools like Zendesk and Intercom for ticketing.

Slab: How does it compare with a general workspace tool?

Slab does less on purpose. There are no databases, boards or task views, which makes it faster to write in and much harder to turn into an unmaintained sprawl.

Slab: Does search really cover other tools?

Yes, connected sources are indexed and appear in results. That integration is the main reason to choose it, so verify your specific tools are supported before committing.
