Verified plans (read 2026-09-19): Starter $29 / month + $0.50 per CPU-hour | Team $100 / month + $0.50 per CPU-hour | Enterprise Not published (contact sales)
Strengths on file: Mage is an open-source data pipeline platform with its source code publicly available on GitHub.; Mage provides a notebook-style and chat-driven web UI for building, running, and monitoring data pipelines.; Mage can be self-hosted using Docker, Kubernetes, or local Python installation.; Mage supports both Python and SQL for defining data transformations within pipelines.
Limits on file: The AI-driven chat features are part of the freemium offering and may be limited or gated behind a paid tier beyond the free open-source core.; Mage is purpose-built for data engineering workflows rather than general-purpose application development.; The product is web-based and does not offer a native desktop or IDE plugin as part of its primary distribution.
Mage is a data engineering platform for building, running, and monitoring data pipelines through a notebook-style, chat-driven web UI.
It is open-source with its code on GitHub, can be self-hosted via Docker, Kubernetes, or a local Python install, and supports both Python and SQL for defining transformations.
It suits data engineers who want to own their infrastructure and work in Python or SQL. It is not for general app-building, and the AI chat features sit in a freemium tier that may be limited or gated behind a paid plan beyond the open-source core. There is no native desktop app or IDE plugin as the primary distribution; it is web-based.
Within pipeline tooling, Mage differs from general-purpose app builders by being purpose-built for data engineering, with self-hosting and an open core as its main draw.

## Tempo (/tools/tempo-labs)
Tagline: Visual AI builder for React apps with team workflows and component libraries.
Category: AI App Builders
Pricing model: freemium
Starts at: Not recorded
Platforms: web
Public repo: none listed
Docs: none listed
Verified plans: none on file
Strengths on file: Web-based visual editor for building React applications with AI assistance.; Supports team collaboration workflows for shared app development.; Integrates with component libraries to scaffold UI elements.; Allows AI-assisted generation of React components and pages.
Limits on file: Focused specifically on the React framework, limiting use for other stacks.
Tempo is a web-based visual AI builder for React apps, with team workflows and component libraries.
It combines a visual editor with AI: AI-assisted generation of React components and pages, integration with component libraries to scaffold UI, and collaboration workflows for teams building together.
It fits React teams that want a shared visual space with AI help. Two limits: it's web-only, with no native desktop app, and it's focused specifically on React, so it's less useful for other stacks.
It's a React-focused, team-oriented visual builder next to v0 and Lovable.
