Linkagent vs LinkTiller

Linkagent crawls websites to identify missing internal links and add links after users approve them. Links can be delivered through a script, WordPress plugin, or JSON API. Its analysis reads a sitemap and maps topics, clusters, orphan pages, click depth, and the in-text link graph. Suggested anchor phrases come from existing page copy, and optional AI review checks them against their original sentence. Crawling, clustering, scoring, and anchor selection work without an AI key; a Claude API key enables additional review. Users approve or reject suggestions, and those decisions persist across re-crawls. Suggestions are balanced at roughly one new link per 250 words, with limits on new inbound links and repeated anchor use. The asynchronous embed script is about 2 KB and wraps existing text without adding or moving page content. Linkagent supports WordPress, Next.js, Shopify, Webflow, and other CMSs. Self-hosting keeps content, link graphs, and review decisions in the user's own Postgres database. Self-hosting costs nothing and requires your infrastructure; hosted plans start at $29 a month.

LinkTiller is a free, self-hosted WordPress plugin that finds posts and pages without incoming internal links and proposes contextual links for review. Its scan is read-only, mapping incoming links and ranking eligible source pages locally before sending a shortlist to the OpenAI-compatible endpoint and model configured by the site administrator. Suggestions show the source sentence, an exact two-to-six-word anchor already in that source, the target page, rationale, and safeguards. Scanning and requesting suggestions never edit content; every insertion requires an administrator’s explicit approval. LinkTiller verifies both pages again and refuses insertion if either changed after review. Each approved link receives a receipt, while Undo restores unchanged prior content or removes only the tagged link while preserving later edits. Requests go directly from WordPress to the chosen endpoint, which may charge separately. No usage telemetry is sent by default. A free v0.2.1 download is listed for WordPress 6.0+ and PHP 7.4+.
