Overview

Baseline Labs Schema Generator turns a live page into JSON-LD structured data by identifying the page type and producing corresponding schema.org markup. It supports more than 20 types, including Article, Product, FAQPage, HowTo, LocalBusiness and SoftwareApplication. The generated output captures the page as it appears at generation time; it is not automatically refreshed when the page changes.

To use the output, users can paste its script tag into the page’s head. The markup is static and requires neither server changes nor extra libraries. The listed capabilities also include schema validation, bulk generation, WordPress support and markup monitoring.

Availability is a current consideration: the generator page says the schema generation service is temporarily offline and submitted pages have been queued for processing. Anyone needing immediate output should take that notice into account.

Baseline Labs was founded by Chris Mortimer in 2025 and is based in Galway, Ireland. The company offers support by email or contact form, and its privacy policy lists info@baselinelabs.ai.

Key features

Static generation and Rolling Schema

The basic generator creates a one-time snapshot. For ongoing changes, the separate Rolling Schema feature re-crawls pages and regenerates their markup on a schedule, with intervals as frequent as every 30 minutes. The Free plan includes Rolling Schema for one domain and five pages; Standard includes auto-injection, while Power provides a priority queue.

API and integrations

The API generates schema.org JSON-LD for a URL. Requests use an X-API-Key header, and the API reference lists insufficient credits and rate limiting among possible errors. API access is included with Power and higher plans; Standard has no API access.

Users can connect Google Search Console and optionally Google Analytics with read-only access to selected properties. Baseline Labs says this data is used to display measurements in its product, not sold, used for advertising or used to train AI models.

Data protection and location

The privacy policy lists HTTPS/TLS encryption in transit, hashed passwords, access controls and network isolation between services as safeguards. The core application and database are hosted in the European Union. GPU inference and globally distributed object storage may involve processing outside the European Economic Area.

Pricing

Pricing is freemium, with a free plan and a seven-day trial for new subscribers to Standard and Power.

Plan	Price	Included
Free	Free	Schema generator tool; Rolling Schema for one domain and five pages. Single-page generation requires no account or card.
Standard	79.00 EUR per month	One domain, 2,500 credits per month and Rolling Schema auto-injection. No API access.
Power	249.00 EUR per month	10 domains, 20,000 credits per month, Rolling Schema priority queue and API access for 1,000 requests per day.
Ultimate	749.00 EUR per month	Unlimited domains, dedicated GPU capacity, white-label reporting, an MCP endpoint, custom deployment and SLA.

The pricing details describe Standard as billed €79 / month and Power as billed €249 / month, each with a seven-day free trial for new subscribers. Ultimate is described as billed €749+ / month.

Platforms

Baseline Labs lists web and API as supported platforms. Its output can be added to a page as a script tag, and WordPress support is also listed.

Who it's for

The one-time generator can suit site owners who want JSON-LD for an individual page without changing server configuration or adding libraries. Rolling Schema is more relevant when pages need scheduled recrawling and regeneration. Teams managing multiple domains or integrating generation into a workflow may need the higher plans, since API access starts at Power and Standard is limited to one domain.

Pros and cons

Pros: Supports more than 20 schema.org types, static script-tag output, WordPress support, validation and bulk generation.
Pros: Rolling Schema offers scheduled refreshes as often as every 30 minutes, with plan options for auto-injection and priority processing.
Cons: The ordinary generator produces a snapshot rather than updating markup as page content changes.
Cons: The generation service is currently described as temporarily offline, with submitted pages queued.
Cons: API access is not included with Standard, and the stated processing locations can extend beyond the EEA for some services.

Verdict

Baseline Labs Schema Generator covers core JSON-LD creation and offers a path from single-page output to scheduled updates, API use and multi-domain management. Its snapshot-based generator is straightforward to embed, but ongoing changes require Rolling Schema rather than the basic output. The temporary service outage is the immediate limitation: check availability before planning around generation. Pricing begins with a free option, while scheduled, API and larger-scale needs map to distinct paid tiers.
