Your visitors don't care about your tech stack
They care about what they read. A typo on your homepage, a grammar error in a product description, a misspelled word in your nav. These small mistakes erode trust regardless of whether your site runs on a CMS or a custom framework. Spling checks what your visitors actually see: your published, rendered, front-end content. Every page, every element, exactly as it appears in the browser.
Works where other tools can't
Platform-specific spell-checkers rely on plugins, app store add-ons, or editor integrations. That's fine if you're on WordPress or Wix. But if your site is built on a JavaScript framework, a headless CMS, a static site generator, or anything custom, those tools don't exist.
Spling doesn't need access to your codebase, your CMS, your hosting environment, or your deployment pipeline. It reads the live site the same way a visitor does. That means it works with any stack, any architecture, any setup.
- Headless CMS setups like Contentful, Sanity, Strapi, or Prismic
- JavaScript frameworks like Next.js, Nuxt, Gatsby, SvelteKit, or Astro
- Traditional server-side builds on Rails, Laravel, Django, or .NET
- Static site generators like Hugo, Jekyll, or Eleventy
- Hand-coded HTML/CSS sites with no CMS at all
- Any combination of the above
Where typos come from in custom builds
Custom-built sites pull content from everywhere. CMS entries, JSON files, hardcoded strings, API responses, database fields, markdown files, environment-specific config. Content passes through multiple contributors: developers, copywriters, marketers, clients. It moves between staging and production, between branches and deploys. Every handoff is a chance for errors to slip through.
And unlike visual builders where someone is at least looking at the text as they place it, content in custom builds often lives in code or data layers where nobody is reading it in context until it's already live.
Even if staging was correct, production might not be.
Last-minute copy changes, environment variable differences, CMS updates that bypass the deploy process, content editors pushing changes directly to production. What you proofread on staging isn't always what ends up on the live site. Spling checks the live version, the one your users are actually reading.
How it works
- Enter your website URL
- Spling crawls every published page on the domain
- Get a full report of spelling and grammar errors across your entire site
- Use filters to target specific directories like /blog/ or /docs/
- Schedule recurring checks and get results emailed to you
No installation. No credentials. No access to your backend. Works with any hosting provider, any framework, any CMS.
Built for sites of any size
A five-page marketing site is easy to proofread by hand. A documentation site with 500 pages, a SaaS product with dynamically generated help articles, or an e-commerce store with thousands of product listings is not. Spling scans at scale. Check an entire site in minutes and catch errors across every page, every route, every piece of published content. Ideal for dev agencies, SaaS teams, and anyone managing content-heavy sites.
