In two years, AI agents went from near zero to high scores on well-known tests. But tests age, leak and measure little of the real world. Here is what the evidence supports as of October 2026.
When a site grows from a few pages to hundreds of articles, the problem is no longer writing but keeping everything consistent. See how Astro solves this with typed collections.
When a site has thousands of content pages, every architectural decision is multiplied. Based on the official documentation and dated field data, see what Astro does well in this scenario and where its limits are.
Astro and Next.js both generate HTML on the server, but they start from different premises: one was born for content sites, the other for React applications. With official documentation and dated field data, see what that changes in practice.
A technical audit done once a quarter is out of date the next day. See how to split the checks into layers that run on their own with every release and fail before the problem reaches the search engine.
Eight languages are not eight copies of the blog. They are one original text, seven translations with their own status, and one simple rule: no language goes live before it is ready.
A static site has no server to answer searches. Pagefind works around this by generating an index after the build, which the browser itself queries. Here is how to set up search in an Astro project.
Cursor is a code editor with a built-in AI agent that reads the project, edits files and runs commands. Understand the workflow, the security controls and what research says about productivity and quality.
Automating deployment takes human error out of the process, but creates a new target: the pipeline has access to production. See how to build an automated deployment that only ships what passed the tests and keeps the keys safe.
A web tool that calls a language model inherits all the risks of an ordinary application and adds others. See what to protect, step by step, before putting it online.
When an AI agent edits files and makes commits, Git becomes your safety net. Based on official documentation, see how to organize branches, review and protections so nothing reaches the main version without you seeing it.
GitHub Copilot ranges from autocomplete to an agent that opens pull requests on its own. See how each part fits into the workflow, what the documentation itself says about its limits and what independent studies found.
Hreflang tells Google that two pages are the same thing in different languages. There are only a few rules, but a single reciprocity error makes the search engine ignore all of them.
All three options solve the same problem, storing and editing a website's content, but they change who can write, where the text lives and what can go wrong. Here are the differences, based on the official documentation.
With 5,000 pages, the structure has to be decided before the content. Here is a seven-step plan, based on Google and Astro documentation, to keep URLs, routes, sitemap and links under control.
A multilingual website starts with URL decisions, not translation. See how Astro organizes languages, when to use its built-in routing and when to build your own.
With Supabase, the browser talks directly to the database. That is only safe if the access rules live in the database itself. See how the three pieces fit together.
A broken link rarely announces that it broke. See how to turn link and route checking into a test that runs after every build and fails before the error reaches the reader.
TypeScript adds to JavaScript a type check that runs before the program does. See what it catches, what it misses, what the studies say and how to start without rewriting your project.
