Free Tier, Full Automation? What Every $0 Website Builder Cuts Off First

You've seen the listicles. "Best free website builders 2025!" Ten tools, a feature table, a verdict that always lands on "generous free tier." Those posts are written for someone dragging and dropping a bakery site over the weekend.

This post is written for a different person: the one whose site was generated by an LLM, who doesn't want to open a dashboard every time a blog post gets written, and who just read about building an MCP pipeline that blogs on a schedule and is now asking the only question that matters before picking a host.

What does the free tier let me automate — and what does it cut off first?

Because here's the pattern almost every $0 tier follows, across nearly every builder and host: the thing they take away isn't storage or bandwidth. It's programmatic access. The APIs, the deploy hooks, the scheduled builds, the headless publishing endpoints. Those are precisely the levers an LLM-driven workflow needs, and they're the first thing behind the paywall.

The three features that decide everything

Forget the feature tables. For an automated publishing pipeline, a free tier lives or dies on three things:

1. Git-based deploys

This is the big one, and it's good news: it's the one feature most free tiers don't gate. If your host deploys automatically when you push to a repository, you already have your automation surface. Your LLM doesn't need the host's API at all — it needs to commit a file and push. The host's dashboard becomes irrelevant; the repo is the interface.

This is why the advice in getting a ChatGPT-built site off the chat and onto a real domain keeps pointing toward static hosts with git integration rather than all-in-one builders. A builder whose free tier says "edits happen through our web editor" is a builder whose free tier says "edits happen manually."

2. Build hooks and deploy triggers

The next tier up: a URL you can hit (from a cron job, an MCP server, a script) to trigger a rebuild. Useful when your pipeline generates content that isn't just committed files — say, content pulled from a CMS or assembled at build time. Some hosts offer these on free plans, some reserve them for paid. If your pipeline idea involves "publish on a schedule, not on a push," check this before you commit to a host. If it's missing, the workaround is usually simple: commit and push on a schedule instead, and let the git-based deploy do the triggering.

3. CMS and form APIs at $0

The sneakiest cutoff. Headless CMSes love to advertise free tiers, and the free tier is often fine for reading content but restrictive around writing it programmatically — rate limits, write caps, or API access moved to paid plans. If your pipeline is "LLM drafts post → posts it to the CMS → site rebuilds," a write-restricted free CMS breaks link number two in that chain. The workaround that always works: keep content as markdown files in the repo. Files have no API limits.

Where the all-in-one builders fall down

The classic free tiers — the Wix-style, Durable-style, Lovable-style products — restrict almost everything an automation wants. Their model is the web editor. Editing through the editor is the product; API access to edit your own site is typically not part of free (and on some platforms, not really part of paid either, or gated behind enterprise tiers).

This is the same ownership question from the AI web creator versus direct prompt decision framework, viewed from the automation angle: a platform where the only interface is a drag-and-drop editor is a platform your scripts can't touch. If you chose the raw-code route, you already won this fight. If you chose a builder and now want automation, the honest answer is usually "rebuild it as files" — which, thanks to your LLM, is less work than it sounds, as covered in the guide to developing a one-file AI landing page into a real multi-page site.

The free-tier trap nobody warns you about: preview URLs

Every $0 tier gives you a branded subdomain — yoursite.platform.com. That part's fine for testing. The trap is building your automation's assumptions on top of it: hard-coded absolute URLs in generated content, RSS feed links pointing at the preview domain, sitemaps generated against it. When you move to your real domain later, your pipeline happily keeps publishing links to the wrong hostname. Set the canonical domain as a config value from day one, and have the LLM read it from there. The DNS and domain setup walkthrough covers the pointing-a-domain part; this is the pipeline-side discipline that pairs with it.

The ranking that actually matters

So here's the compressed version, no feature table:

1. Static host with free git-based deploys — best free-tier automation surface, period. Your LLM works in files and pushes; deploys happen. Deploy hooks, if present, are a bonus, not a requirement.
2. Static host + file-based content — same as above, but with your content in the repo as markdown. Nothing to rate-limit, nothing to paywall. This is the setup the monthly maintenance routine assumes.
3. Static host + headless CMS free tier — workable, but verify write access is included at $0 before building your pipeline around it. Read-only free tiers are common and quietly fatal to this architecture.
4. All-in-one AI builders — fine for a manual site, effectively incompatible with an automated one at $0. The editor is the interface, and the editor is yours to click, not your script's.

The one-sentence test

Before you pick a $0 tier, ask it one question: "Can a script, with no human at a dashboard, get new content onto my live site?"

If the answer is "push a file to a repo" — you're golden. If the answer is "log in and click Publish" — the free tier isn't actually free for the workflow you're building. You'd be paying in manual labor every single month, which is exactly the tax you started this whole automation project to avoid.
