When does building MSP IT Documentation make sense?

Self-hosted Hudu covers vault and wiki functions cheaply for small MSPs with manageable client counts willing to maintain documentation manually. The limit is the auto-discovery connector breadth — that's not replicable internally.

When does buying MSP IT Documentation make sense?

Buying earns its keep for MSPs with multi-RMM, multi-PSA, and cloud clients where documentation accuracy depends on automatic discovery. Static docs that lag behind client reality degrade incident response and tech onboarding quality.

What are the main MSP IT Documentation vendors?

Representative vendors include Liongard, Hudu (with integrations), Auvik (documentation layer), IT Glue (with automation connectors). B4 Pro scores the full set.

Should you build or buy IT Documentation & Knowledge for MSPs (Automated Discovery-Driven)?

IT Documentation & Knowledge for MSPs (Automated Discovery-Driven) combines a structured wiki and credential vault with auto-discovery connectors that continuously pull live configuration data from RMMs, PSAs, cloud APIs, and network devices across a managed client fleet. Rather than relying on technicians to document manually, the platform keeps client environments, network diagrams, and runbooks current automatically as infrastructure changes.

The build-vs-buy decision for MSP IT Documentation turns on how much of the value comes from the auto-discovery connector breadth versus the documentation and vault functions alone; the specifics decide it — and for MSPs, the connector network is almost always the deciding factor.

Build it, buy it, or bridge?

	Build it	Buy it	Bridge (buy, then extend)
Cost shape	Self-hosted Hudu covers vault and wiki cheaply; auto-discovery connector breadth cannot be replicated	Per-user per-month at MSP scale; justified by documentation staying current without manual effort	Hudu self-hosted for vault and docs; vendor discovery connectors layered on top
Time to value	Days for a static wiki; months to approximate auto-discovery depth	Weeks to connect RMM, PSA, and cloud platforms; documentation self-populates	Static docs active quickly; discovery integration extended as budget allows
Differentiation captured	Documentation quality and accuracy directly affect MSP incident response speed	Auto-updated documentation improves tech onboarding and client handoff quality	Vault and standard runbooks in-house; auto-discovery feeds the hardest-to-maintain sections
AI feasibility today	Static wiki tools are trivially buildable; 100+ discovery connectors are not replicable	AI-generated runbooks and client summaries emerging as connector-fed features	Self-hosted docs plus vendor discovery layer feeding AI runbook generation
Who it fits	MSPs with a small, homogeneous client fleet willing to maintain docs manually	MSPs with multi-RMM, multi-PSA, and cloud clients needing always-current documentation	MSPs with cost pressure who can phase in connector depth over time

When building IT Documentation & Knowledge for MSPs (Automated Discovery-Driven) makes sense

The build case is mostly about cost tolerance and scale. Hudu self-hosted covers the vault and wiki functions at low cost, and for a small MSP with a manageable client count and relatively homogeneous tech stacks, manually maintained documentation is a workable approach. Static wiki tools are trivially buildable, and password vaulting is a solved problem. The floor of what self-built covers is legitimate: technicians who know their clients well can keep documentation reasonably current if the client count is small enough. The ceiling is the auto-discovery connector network — building integrations to 100-plus RMMs, PSAs, and cloud APIs is years of connector development that no MSP should attempt to replicate internally.

When buying IT Documentation & Knowledge for MSPs (Automated Discovery-Driven) makes sense

Liongard and IT Glue with automation connectors earn their keep because the auto-discovery connector network is where this category's value lives. An MSP that tries to approximate auto-discovery with a static wiki or Hudu without integrations ends up with documentation that's always behind reality, which defeats the purpose for incident response, new tech onboarding, and client handoffs. The connector breadth takes years and significant capital to build — it's the moat that commercial vendors have, and it's not something an MSP engineering team can replicate. AI is raising the stakes further: auto-generated runbooks and client-specific network summaries are becoming realistic as connected discovery data feeds those models, which makes the connector layer more valuable over time rather than less.

The auto-discovery connector network is where this category lives or dies. Tools like Liongard and IT Glue with automation connectors pull live configuration data from RMMs, PSAs, cloud APIs, and network devices across a client fleet, and that breadth takes years and significant capital to build. An MSP that tries to approximate this with a static wiki or Hudu without integrations ends up with documentation that's always behind reality, which defeats the purpose.

Buying earns its keep when your tech stack spans multiple RMMs, PSAs, and cloud platforms and you need documentation that stays current without manual effort. The build case is mostly about cost tolerance: Hudu self-hosted covers the vault and wiki functions cheaply, but you're trading automation depth for price. AI is making auto-generated runbooks and client-specific network summaries more realistic, which raises the stakes on having a connected discovery layer to feed those workflows.
