Baseline Labs Schema Generator

Overview

Baseline Labs Schema Generator turns a live page into schema.org JSON-LD, making it a fit for teams that need structured data without adding libraries or changing server code. Its broad type coverage and scheduled refresh option are useful, but the generator is currently offline, and API access starts only with Power.

Key features

Generation and installation

The tool identifies a page type and generates JSON-LD for more than 20 schema.org types, including Article, Product, FAQPage, HowTo, LocalBusiness and SoftwareApplication. You can paste the resulting script tag into a page’s head; the static markup needs no server changes or extra libraries. That makes it practical for straightforward implementation, though the one-time output reflects the page only as it appeared when generated.

Scheduled refreshes

Rolling Schema re-crawls pages and regenerates markup on a schedule, as often as every 30 minutes. That is the more relevant option for pages whose content changes regularly; the basic snapshot alone will not keep markup current. Free covers one domain and five pages, while Standard adds auto-injection and Power puts Rolling Schema jobs in a priority queue.

API, validation and integrations

The API generates schema.org JSON-LD for a URL and uses an X-API-Key header. Power includes up to 1,000 requests per day; insufficient credits and rate limiting are among the API’s error responses, so API users need to account for both quota and request limits. Schema validation, bulk generation, WordPress support and markup monitoring broaden its usefulness beyond one-off output.

Users can connect Google Search Console and optionally Google Analytics with read-only access to selected properties. Baseline Labs says connected data is used to display measurements in its service, not sold, used for advertising or used to train AI models. Its stated safeguards include HTTPS/TLS encryption in transit, hashed passwords, access controls and network isolation between services. The core application and database are hosted in the EU; GPU inference and globally distributed object storage may involve processing outside the EEA.

Pricing

The freemium structure ranges from an account-free single-page generator to custom deployment and SLA options. The plans suit distinct workloads, but the cheaper tiers make meaningful trade-offs in page capacity and API access.

Free is a low-commitment way to generate a single page or maintain a small five-page set, but it is not a route to API access. Standard fits a single-domain workflow that values auto-injection and can work within 2,500 monthly credits; its 7-day trial lets new subscribers evaluate the paid tier. Teams needing multiple domains or programmatic generation must move to Power. Ultimate targets deployments that need dedicated capacity, white-label reporting or custom terms; its price is 749.00 EUR per month, with the plan price shown as €749+ / month.

Platforms

Baseline Labs supports web and API use. The web tool is the accessible path for single-page generation, while the API is gated to Power and above. The company, founded by Chris Mortimer in 2025, is based in Galway, Ireland; support is offered by email or contact form.

Who it's for

This is best suited to site owners and SEO teams who need several schema types, want static JSON-LD they can place directly in a page, or need scheduled refreshes across a managed set of pages. Free is suitable for small-scale use, and Standard for one-domain refresh workflows. It is a weaker fit for teams that require API access at a lower tier, or immediate generation while the service remains offline.

Pros and cons

• Pros: More than 20 schema types cover common content and product pages, reducing the need to switch tools for different markup needs.
• Pros: Static output can be added without server changes or extra libraries, which keeps implementation simple for teams controlling their page markup.
• Pros: Rolling Schema can refresh as often as every 30 minutes, with auto-injection on Standard and priority queue access on Power.
• Cons: The generator is temporarily offline and submitted pages are queued, a direct obstacle for anyone needing output now.
• Cons: Standard has no API access; teams automating generation must pay for Power, which starts at 249.00 EUR per month.
• Cons: Free Rolling Schema is limited to one domain and five pages, so it is suited to small coverage rather than a broad site.

Alternatives

Schema Markup Tools is a directory of schema markup options for readers comparing tools across the category.

• Rolling Schema is the closer fit when scheduled schema maintenance is the primary need: its Free plan includes one domain and five rolling-schema pages, but no API access.
• JSON Schema App SaaS Schema is worth considering for a web-based free starting point capped at 50 URLs, with Product, Service and Article schema types and a schema checker.
• SchemaValid suits readers who want a free browser-based tool with no account or installation.
• StructuredValidator is another free web option with no signup stated.
• Schema & Structured Data for WP & AMP is the alternative to consider for a self-hosted WordPress-oriented setup.
• Schema Markup Info is a free web-based alternative.
• Schema App is a paid alternative with custom scope and complexity pricing, a one-time strategy and setup fee that varies by scope, and a 12-month minimum subscription.
• Schema offers a freemium alternative with Personal, Business and Extended passes; plan prices are custom pricing.

Verdict

Choose Baseline Labs Schema Generator if you want broad schema coverage, simple static installation and the option to keep markup refreshed as pages change. Its Free tier is a sensible starting point, while Power is the relevant plan for API-led or multi-domain work. Look elsewhere if generation must be available immediately or if API access is required below Power.
