Is Relinka really free?

Yes. The WordPress.org plugin is free and fully functional — link analysis, health score, orphan and broken-link finders, and reason-based suggestions — with no account and no API key. An optional Pro add-on adds AI and automation, but it is never required.

Is Relinka as good as Link Whisper?

It depends on what you need. Link Whisper is more established, has a larger install base, and offers AI-assisted suggestions even in its free tier. Relinka wins on a fully-featured free tier (broken-link finder included, no caps), a deterministic on-server engine (no AI, nothing sent off-site), explainability (a reason for every link), and safety (one-click undo with a snapshot). Pick the one whose trade-offs fit you.

Does my content leave my site with Relinka?

No. The free plugin runs entirely on your own server and does not phone home. Nothing is sent off-site. Pro's optional AI uses your own Google Gemini key when you enable it.

Does Relinka need an account or API key?

No. The free plugin works with no account and no API key. Everything runs locally on your server.

Link Whisper Alternative — Relinka, the free internal linking plugin

Why people look for a Link Whisper alternative

Three reasons come up again and again. Relinka was built around all three.

Price & caps

Link Whisper's free version is limited — bulk linking, auto-linking, broken-link reporting and full reports need the paid Premium. Relinka's whole toolkit, including the broken-link finder, is free with no caps.

Private & predictable

Relinka's free tier uses no AI — suggestions are built from your own text, on your own server, and nothing is sent off-site. Predictable results, and nothing to sign up for.

Control

Every suggestion comes with a one-sentence reason, the anchor is taken word-for-word from your text, and any change reverts in one click with a before/after snapshot.

Relinka vs Link Whisper — an honest side-by-side

We won't claim to be better at everything. Here's where each one leads, so you can pick on the trade-offs that matter to you.

	Link Whisper	Relinka (free)	Relinka Pro
Price to start	Free (limited) or paid Premium	Free, fully functional	from $59 / yr
Broken-link finder	Premium only	Included free	Included
A reason for each suggested link	Rarely shown	One plain-English sentence	Yes
Anchor text	Auto-generated	Verbatim from your content	Verbatim from your content
Undo a change	Manual	One-click revert + snapshot	One-click revert + snapshot
Placement guards	Limited	Won't split a list/lead-in or a CTA	Same
Health score & cluster graph	Partial	Built in, free	Built in
Suggestion engine	AI-assisted	Deterministic, on your server	Semantic AI (your own key)
Bulk apply & auto-link on publish	Premium	—	Included
Maturity & install base	Established, large	Newer	Newer

Choose Link Whisper if a large install base, maturity, and AI suggestions in the free tier matter most. Choose Relinka for a fully free, on-server, explainable workflow — broken-link finder included, undo in one click — and add Pro only if you want semantic AI and automation later.

Where Link Whisper is genuinely ahead

An honest alternative page should say it plainly.

It's more mature, with years of releases and a large user base.
Its free tier already includes AI-assisted suggestions; Relinka's free tier is deterministic (no AI), with AI in the optional Pro add-on.
It has a big library of tutorials and reviews built up over time.

If those are your deciding factors, it's a solid choice. Relinka's bet is different: do the core job for free, keep it private and reversible, and explain every link. When you're ready to automate internal linking safely, Pro adds auto-linking on top of the same reversible workflow.

What Relinka gives you — free

Internal link analysis & a link graph — inbound/outbound counts and a keyword cluster view.
An internal-link health score (0–100) with one-click orphan fixes.
Orphan-page and broken-link finders in a single list.
Relevant link suggestions with a reason, anchors taken from your own text.
One-click apply and undo — every change is a revertable snapshot.
