Changelog

What changed in the product, the headlark CLI and the Netlify plugin. Newest first.

Product

2026-10-21

• Default share image: set one per site in the dashboard, and pages without an og:image get it in their link previews. Your own og:image is never replaced, and adding or changing the default uses no rewrites. Build step and WordPress; Webflow's API can't set images.
• Free tools: a site checker (up to 50 pages from your sitemap), an llms.txt generator and a structured data checker.
• Pages served compressed (gzip, deflate, Brotli) even when asked not to are read correctly by the free tools and deploy hooks.
• The free tools check pages as crawlers see them, including SEO Headlark wrote. JSON-LD written as an array or with @graph is no longer flagged as missing @context.

2026-10-20

• Dashboard: the next invoice, extra rewrites in your plan's currency, and recent activity per site.
• A page that's already waiting in a batch isn't queued, or counted, a second time.
• Webflow: the built-in 404 and password pages are skipped. The SEO we write back into a Webflow page no longer counts as a content change, so it doesn't use a rewrite.
• The CLI stops with an upgrade message when the API needs a newer version.
• Terms, privacy policy, data processing agreement and cookie statement published.
• Sign-in emails have a plain reply address and an HTML version.

2026-10-19

• Launch: pricing, these docs, and the headlark CLI and netlify-plugin-headlark on npm.
• Customer dashboard at /app: sites, secret keys, usage and billing.
• Export your data or delete your account from the dashboard. Webflow tokens are stored encrypted.
• Functions and data storage moved to EU regions (Frankfurt and Stockholm); some providers are US companies, listed in the DPA.
• Rebuilds stay free through incidental changes: timestamps, counters, tokens and asset hashes don't count as new content.
• Deploy hooks read your whole sitemap.
• Rate limits and security headers on every endpoint; daily backups and hourly uptime checks.

2026-10-18

• Nothing runs when someone views your page: the snippet reads SEO published at deploy time from a cached file.
• SEO for pages found by a deploy or publish webhook is written in a batch at half the cost.

headlark CLI

0.1.3 2026-10-20

Fixed

• --site-url keeps its path, so sites under a base path (GitHub Pages project sites, Vite base, Next.js basePath) get correct canonicals.
• Files that aren't UTF-8 are left untouched.

Changed

• Without --strict the CLI never fails your build: a missing key, output folder or --site-url is reported and every page stays as built.
• Error pages, redirect pages and verification files are skipped byte for byte; an unknown key or a URL outside your site stops the run with a clear message.
• Retries rate-limited or dropped requests, and keeps your own tags when a generated value is empty.

0.1.2 2026-10-20

Added

• The CLI stops with an upgrade message when the API needs a newer CLI (x-headlark-min-cli response header).
• This changelog ships in the package.

Changed

• No repository link in the package metadata.

0.1.1 2026-10-20

Changed

• Published from GitHub Actions through npm trusted publishing (no provenance: the source repository is private).

0.1.0 2026-10-19

Added

• First release: headlark <output dir> --site-url <url> writes AI-generated SEO tags into every built .html file.

astro-headlark

0.1.0 2026-10-21

Added

• Astro integration: runs Headlark on the build output after astro build, using site and base from astro.config. Skips without HEADLARK_KEY or site; fails the build only with strict: true. Docs.

netlify-plugin-headlark

0.1.3 2026-10-20

Changed

• Runs on production deploys only, so deploy previews and branch deploys don't use your plan.
• Never fails a deploy unless strict = true, and works when installed from the Netlify UI.

0.1.2 2026-10-20

Added

• This changelog ships in the package.

Changed

• No repository link in the package metadata.

0.1.1 2026-10-20

Changed
