Notis vs Base44 vs Duet

Verdict

Notis aside, Base44 has the highest support score, 76% across all 33 rows, ahead of Duet at 61%.

Their strengths differ: Base44 for operating workflows in production and Duet for combining AI agents with human checkpoints.

Base44 and Notis tie for the cheapest way in at $0, and none of those free plans does the product's main job.

None of them documents Loops and batch processing, Data mapping and transforms or Open source.

Only Base44 documents Visual workflow builder, Conditional branches and Workflow versioning.

Ranked by support score

1. Base44

No-code app builder with scheduled/triggered workflow automation and an autonomous cross-tool AI agent (Superagent)

Base44 automates backend work through scheduled or event-triggered Workflows inside an AI-built app, and through Superagent, a cross-tool autonomous agent that browses, connects to services via MCP and connectors, and runs its own workflows.

Best for: operating workflows in production

Documented strengths

Build & trigger: Visual workflow builder, Build workflows with natural language, Schedule trigger, App-event trigger, Webhook or API trigger and Email, form, or manual trigger
AI & human control: AI model steps, Autonomous agents, Knowledge bases or RAG, Browser or computer use and MCP support
Platform & governance: Ready-made app integrations, Managed cloud, SSO and role-based access, Audit logs and compliance and Shared team workspace

The catch

The gap is workflow logic, with nothing documented for Loops and batch processing, Data mapping and transforms and Reusable subflows.
