A governed AI coworker, not an early-stage toolkit.
PipesHub is an open-source enterprise knowledge platform, actively developed and earlier on the maturity curve. ZenSearch is a production-grade AI coworker: it answers with citations and takes governed action — approval-gated writes, automations on triggers — on infrastructure you own, with mature guardrails and a SOC 2-ready posture.
The Short Version
Choose ZenSearch if you need:
- A coworker that takes governed action, not just retrieval — approval-gated writes and automations
- Mature input and output guardrails (prompt injection, PII, hallucination scoring)
- CRM/ERP connectors (Salesforce, SAP, HubSpot) plus NL-to-SQL over four database engines
- A centralized Model Gateway with per-team rate limits and usage tracking
- SOC 2-ready posture with audit logging and multi-tenant isolation
Choose PipesHub if you need:
- A fully open-source codebase with community contributions
- Self-hosted deployment with complete source access and no vendor dependency
- An actively developed project focused on document and collaboration tools
- Freedom to fork and extend the core platform yourself

Where ZenSearch Stands Apart
Where the production gap shows up.
PipesHub is open-source and moving fast. These are the places where ZenSearch is built as a governed, production-grade coworker — and where that difference shows up in security review, in spend control, and in what the agent is actually allowed to do.
Governed action, not just answers
ZenSearchEach tool carries a risk tier (T0–T5). Consequential writes pause the run and route an approval to the right human — in Slack, Teams, or on the web — backed by reasoning traces and audit logs. Automations run the same governed loop on a cron, email, event, or meeting trigger.
Governed action, not just answers
PipesHubPipesHub focuses on retrieval and cited answers. Per-action risk tiers, cross-surface human approvals, and trigger-based automations are not part of the platform today.
Mature input + output guardrails
ZenSearchInput and output guardrails — prompt injection detection, PII filtering, hallucination scoring (lexical, semantic, hybrid), and toxicity filtering — with per-tenant configuration and hot-reload.
Mature input + output guardrails
PipesHubPipesHub does not include built-in guardrails for prompt injection, PII detection, or hallucination scoring.
NL-to-SQL & CRM/ERP connectors
ZenSearchQuery PostgreSQL, MySQL, ClickHouse, and SQL Server in plain English with schema discovery and read-only validation. Connect Salesforce, SAP, and HubSpot for CRM/ERP data — 18 first-party connectors in total.
NL-to-SQL & CRM/ERP connectors
PipesHubPipesHub focuses on document and collaboration tool connectors. Direct database querying and CRM/ERP integrations are not available.
Centralized Model Gateway
ZenSearchEvery model call routes through a Model Gateway with per-team rate limits, per-tenant usage tracking, cost monitoring, and zero-downtime provider switching across OpenAI, Anthropic, Cohere, Groq, Azure, Bedrock, and local models.
Centralized Model Gateway
PipesHubPipesHub calls model providers directly. Centralized usage tracking and rate limiting would need to be implemented separately.
A Closer Look
Open-source toolkit vs production-grade coworker
PipesHub gives you an open, self-hostable knowledge platform you can fork and extend. ZenSearch gives you a governed AI coworker that's ready for an enterprise security review. Here's the trade-off, side by side.
