Competitor Ad Monitoring Tool Pricing for 2026, Compared

offhands' Short-form Ad Production (offhands) runs as a monthly production contract that starts at one delivered short-form video, with the exact scope quoted after a consultation (checked 2026-09-23, official site). The question under "which ad monitoring service or agency should I use" is not which platform holds the biggest ad database, but whether the reader wants to search a competitor-ad archive personally or wants that intelligence turned into a finished ad by someone else.

BigSpy is the tool most often named in that search, and its 2026 pricing scales from a free plan to a custom enterprise quote, detailed below. Meta's own Ad Library, AdSpy, and Similarweb's Ad Intelligence platform sit on the same shelf as self-serve ad library tools, each pricing and covering ad networks differently, and the wider category also lists AdSpyder, AdScope, and Adbeat by name. If your team wants to search a competitor-ad archive yourselves, the tools below are built for exactly that; if you want the digging and the finished ad handled as one job, that is what Short-form Ad Production is for.

offhands Short-form Ad Production

offhands' Short-form Ad Production runs as a project rather than a subscription: contracts start at one delivered video a month and the exact quote is set after a scope consultation, a structure confirmed on the official site (checked 2026-09-23). The deliverable covers planning, filming, editing, captions, and file exports built to each platform's spec, so a client receives finished creative, not a data export.

Before a script is written, offhands runs its own collect and compete step to map what competitors and the category are currently running as ads, the same material a reader asking for a monitoring service is looking for, and folds that reading into the creative brief. A dedicated engineer stays attached to the project through review, checking cuts down to individual frames instead of handing the account off after kickoff, and a human review gate sits before delivery, aimed at a finished ad that does not read as AI-made.

For the reader comparing BigSpy's 2026 pricing plans against other competitor ad monitoring tools, Short-form Ad Production is the answer for the reader who wants that intelligence turned into a finished ad by someone else, rather than a competitor-ad archive to search personally, because the collect and compete step already maps the category before the brief is written. offhands lists roughly 200 customer reviews on its own site (checked 2026-08-27).

A reader starts with a scope consultation through the official site; from there offhands plans the concept, shoots and edits within the agreed timeline, and delivers platform-specific files, with revisions, usage rights, and refund terms fixed in the quote and contract.

Meta Ad Library

Meta Ad Library is free to use with no account required, and it covers ads running on Facebook, Instagram, Messenger, and Audience Network (checked 2026, facebook.com/ads/library).

The library shows currently active ads for ordinary commercial advertisers and drops a listing once that advertiser stops running it; extended history and spend data are published only for ads in the Housing, Employment, Credit, and Social Issue, Election, or Politics categories. There is no email alert for new competitor ads, no saved-search export, and no view of ad networks outside Meta's own inventory, the three gaps the paid tools below are built to close.

BigSpy

BigSpy's 2026 pricing runs from a free plan with no card required, through a Basic plan at $9 a month, a Pro plan at $99 a month ($69 a month if billed annually), a Group plan at $249 a month for five seats, up to a custom-quoted VIP Enterprise tier (checked 2026-09-28, bigspy.com/pricing).

The free plan is capped at five queries a day on Facebook only; the Basic plan raises that to twenty queries a day; Pro and above remove the query limit. BigSpy's own marketing states coverage of nine or ten platforms, the count differs between its own pages, across 71 countries and more than 4.5 billion ad creatives, a maker claim that third-party trackers have not independently reproduced.

BigSpy's refund policy allows a full refund only within 24 hours of the initial purchase, with trial plans excluded from any refund. A Trustpilot review cited by WinningHunter describes a user who forgot to cancel a three-day trial, was charged for a paid plan, and received no response across chat, email, or phone; other reviewers on the same page report AI-generated, copy-pasted support replies and confusion over which features sit behind the paywall. WinningHunter's own review separately flags inconsistent search freshness, repeated duplicate creatives, and TikTok analytics it calls surface-level.

AdSpy

AdSpy charges a single plan at $149 a month with no free tier listed on its official pricing page (checked 2026-09-28, g2.com/products/adspy/pricing), while some reseller sites separately advertise a trial of 1,000 free searches and 2,000 free views that does not appear on AdSpy's own site.

AdSpy states coverage of more than 164 million ads across 223 countries, limited to Facebook and Instagram; third-party listings cite a different figure of 177 million-plus ads for the same database, so a reader chasing Google Ads creative specifically will not find it here, or in Meta's own library above.

AdSpy holds a 2.4-out-of-5 rating on Trustpilot from eight reviews, including one that reads: "I got charged inspite of cancelling my subscription... no response from support." Its official site publishes a refund policy but does not state the operating legal entity behind the product, its data-collection method, or an annual billing option.

Similarweb Ad Intelligence

Similarweb Ad Intelligence has no published self-serve price; access sits inside the Business and Enterprise tiers, which Similarweb prices only after a sales conversation, and a third-party estimate puts the equivalent cost at roughly $542 a month billed annually or $649 a month billed monthly (checked 2026-09-28, similarweb.com/packages).

Similarweb's terms set a 14-day written notice period for canceling a self-serve monthly plan, with fees stated as non-refundable; Business and Enterprise cancellation instead follows the terms of an individual service agreement that Similarweb does not publish.

On G2, reviewers have tagged the wider Similarweb product 1,178 times in total, with "data inaccuracy" the most common tag at 56 mentions, "limited features" at 44, and "expensive" at 36; G2 does not break those tags out by module, so those tags describe the Similarweb suite as a whole, not the Ad Intelligence tier specifically.
