Baseline Labs Schema Generator

Overview

Baseline Labs Schema Generator turns a live page into schema.org JSON-LD, making it a fit for site owners and developers who need structured data across varied page types. Its breadth and scheduled regeneration are useful strengths, but the service’s current offline notice makes availability a real caveat.

The generator supports more than 20 schema types, including Article, Product, FAQPage, HowTo, LocalBusiness and SoftwareApplication. Its standard output is a snapshot of a page at generation time, so changes to the page do not automatically update that markup. Users can paste the resulting script tag into a page’s head; the markup needs no server changes or extra libraries.

Schema validation, bulk generation, WordPress support and markup monitoring are also listed capabilities. Baseline Labs was founded by Chris Mortimer in 2025 and is based in Galway, Ireland. Support is available by email or contact form.

Key features

One-time generation and rolling updates

A one-time snapshot is sufficient for a page that changes infrequently, but it can become stale as content evolves. Rolling Schema addresses that trade-off by re-crawling pages and regenerating markup on a schedule, as often as every 30 minutes. Free covers one domain and five pages; Standard adds auto-injection, while Power adds priority queue access.

API and integrations

The API generates JSON-LD for a URL and uses an X-API-Key header. API access starts with Power, which includes up to 1,000 requests per day; requests can encounter insufficient-credit and rate-limit errors. Users can connect Google Search Console and optionally Google Analytics with read-only access to selected properties. Those data are used to display measurements in Baseline Labs, not sold, used for advertising or used to train AI models.

Privacy and security

Baseline Labs describes HTTPS/TLS encryption in transit, hashed passwords, access controls and network isolation between services. Its core application and database are hosted in the European Union, though GPU inference and globally distributed object storage may involve processing outside the EEA. That distinction matters to organizations with strict data-location requirements.

The generator page currently says the schema generation service is temporarily offline and submitted pages have been queued. That is a material limitation for users who need output immediately.

Pricing

The Free plan costs nothing. It includes the schema generator and Rolling Schema for one domain and five pages; single-page generation requires no account or card. It is the sensible starting point for individual use, but its rolling coverage is narrow and it has no stated monthly credit allowance.

Standard costs €79 a month, billed €79 / month. It covers one domain, 2,500 credits per month and Rolling Schema auto-injection, with a 7-day free trial for new subscribers. It suits a single-domain operation that wants automatic markup insertion, but has no API access.

Power costs €249 a month, billed €249 / month. It raises coverage to 10 domains and 20,000 credits per month, adds Rolling Schema priority queue access and API access for 1,000 requests per day, and includes a 7-day free trial for new subscribers. It is the more appropriate tier for multi-domain workflows or API use, though its daily request ceiling remains relevant.

Ultimate costs €749 a month, billed €749+ / month. It includes unlimited domains, dedicated GPU capacity, white-label reporting, an MCP endpoint, and custom deployment and SLA. It targets organizations needing dedicated capacity or deployment terms beyond the lower plans; the published price has a plus sign, so the monthly cost may exceed €749.

Platforms

The product is offered on web and through an API. WordPress support is also among its capabilities, which may suit publishers using that platform, while API access is reserved for Power and above.

Who it's for

Baseline Labs is best suited to site owners managing several schema types, especially those whose pages benefit from scheduled recrawling rather than a static snapshot. Free is a low-commitment way to try single-page generation and limited rolling coverage. Teams needing API access or multiple domains will need Power, while buyers requiring immediate service should wait until generation is available again or choose another tool.

Pros and cons

Pros

• Broad schema coverage: More than 20 types accommodate varied pages, from products and articles to local businesses and software.
• Scheduled regeneration: Rolling Schema can refresh markup as often as every 30 minutes, reducing the upkeep of changing pages.
• Static output is straightforward to deploy: A script tag can be placed in the page head without server changes or extra libraries.
• Free single-page entry: Generation needs no account or card, and the free tier includes limited Rolling Schema.

Cons

• Generation is temporarily offline: Queued submissions do not help users who need working output now.
• Snapshots can age: One-time markup does not refresh when source pages change unless Rolling Schema is used.
• API access requires a higher tier: Standard excludes it, and Power still caps usage at 1,000 requests per day.
• Processing may extend beyond the EEA: GPU inference and object storage may involve data processing outside the region.

Alternatives

Schema Markup Tools is a directory for comparing schema markup options. Consider JSON Schema App SaaS Schema if a free web tool limited to Product, Service and Articles is enough: its Basic Plan covers up to 50 URLs and includes a checker and LLMs.txt generator. Rolling Schema is a focused alternative for scheduled markup, with a free tier covering one domain, 500 credits per month and five rolling-schema pages, but no API access.

SchemaValid suits readers seeking a free, browser-based option with no account or installation. StructuredValidator is another free web tool with no signup stated. Schema Markup Info is a free web alternative.

For WordPress users, Schema & Structured Data for WP & AMP offers a self-hosted option; its PERSONAL license costs $99 a year and renews after one year. JSON-LD Generator is a free web tool with 17 schema types and no signup stated. Schema offers freemium passes for different site counts and extension bundles, with custom pricing.

Verdict

Choose Baseline Labs Schema Generator if you need varied schema types and want markup to refresh on a schedule, with a free tier for a small initial workload and higher plans for API or multi-domain use. Its main appeal is the combination of broad generation and Rolling Schema; its main reason to look elsewhere is the current service outage, compounded by the fact that one-time output can become stale.
