Quick answer
Yes — for the part of Semrush covered on this page, Serpdeck is a one-time-purchase alternative. It costs $99 once, while Semrush lists from $139.95/mo. Daily position history, competitor overlays and big-move alerts — BYO SerpAPI/DataForSEO key, pennies per check. It is not a 1:1 replacement for everything Semrush does — the honest limits are spelled out below.
The verdict
Switch to Serpdeck if the slice of Semrush you actually pay for is the slice Serpdeck covers — and a $99 one-time price beats from $139.95/mo for as long as you use it.
Stay with Semrush if this sounds like you — Semrush's keyword database, backlink index, content tools and PPC data are decades of aggregated crawl data. Serpdeck tracks rankings you already care about; it cannot do keyword discovery.

Where Serpdeck wins
The rank-tracking tab is where many Semrush subscriptions actually live. Serpdeck does daily position tracking with history charts, competitor overlays and big-move alerts — bring your own SerpAPI or DataForSEO key and pay pennies per check. $99 once instead of $1,679/yr.
- Price, permanently. $99 once versus from $139.95/mo for as long as you use it. There is no renewal, no seat count and no tier gate.
- Unlimited everything. Unlimited projects, keywords and competitor domains — no per-seat or per-keyword pricing tiers.
- Daily automatic checks. Per-project schedule (pick the hour), plus manual "check now" for a single keyword or a whole project.

- After 1 year: Serpdeck has cost you $99 total — Semrush has cost ~$1,679.4.
- After 3 years: Serpdeck is still $99 — the subscription is at ~$5,038.2.
- After 5 years: Serpdeck is still $99 — the subscription is at ~$8,397.
Common questions
Is it really free on GitHub?
Yes — the full source is MIT at github.com/bensblueprints/serpdeck-mvp. The $99 buys the packaged installer and updates for people who'd rather not git clone.
Why do I need my own API key? Why not just scrape Google?
Because direct scraping is a non-starter for a product: Google CAPTCHA-walls datacenter IPs within dozens of queries, it violates Google's ToS, accurate geo/device targeting needs proxy infrastructure the API providers already run at scale, and every Google markup change would break every install. SERP APIs cost fractions of a cent per keyword — a fairly active install (100 keywords daily via DataForSEO) runs $2-6/month. There is no direct-scrape mode, and there never will be.
What does tracking actually cost per month then?
DataForSEO is roughly $0.0006-$0.002 per SERP pay-as-you-go; SerpAPI is ~$75 for 5,000 searches. The $99 one-time price works precisely because the recurring metered cost is yours directly, at provider rates, not marked up into a subscription.
What does AccuRanker do better?
Plenty, honestly — it's a polished agency product with integrations, share-of-voice analytics and multi-user features Serpdeck doesn't have. Serpdeck is for solo SEOs, lean sites and agencies who want to own the infrastructure and pay API costs directly instead of renting a dashboard.
