Can I use these numbers in an article or a client alert?

Yes. The dataset is licensed CC BY 4.0. Cite the line on this page and link to it. If you need a cut that is not here, such as a single county or a single firm over several years, email hello@suitcast.com.

Why do your numbers differ from another tracker's?

Different inclusion rules. Suitcast counts only cases verified as website cases and excludes physical-access ADA suits, criminal wiretap matters and appellate dockets; other trackers may count every ADA Title III filing or include state courts more fully. The methodology page lists the rules so the difference can be reconciled.

How do I report an error?

Email support@suitcast.com with the case link. A wrong industry, a wrong state or a case that is not a website case is corrected in the next daily rebuild, and the change is noted in the changelog if it affects published totals.

The JSON file on this page is the public interface: every aggregate, refreshed hourly, cacheable, no key required. Per-case data is on the state, firm and tracker pages, with a link to each court record.

The short answer

Suitcast publishes daily counts of US website lawsuits: Americans with Disabilities Act, ADA, cases about websites and California Invasion of Privacy Act, CIPA, cases about website tracking. Suitcast verifies each case itself, from CourtListener's federal court records and from sourced state filings. The dataset holds 834 accessibility filings in the last 12 months and 420 tracking filings in the last 12 months, grouped by state, industry, plaintiff firm and tracking script. It is free to use with attribution.

Filings on record, 12 months

01What is counted

Two kinds of civil filing in US federal district courts, plus curated state-court filings that have a public source. Accessibility cases are ADA Title III suits that concern a website, verified by the plaintiff firm, the plaintiff, or the complaint text. Tracking cases are CIPA suits that concern tracking scripts on a website, identified by the statute sections and tracking terms in the record.

Criminal wiretap and pen-register matters, appellate dockets and physical-access ADA suits are excluded. The methodology page states every rule.

02How counts are attributed

State
Rule
Accessibility: the court's state, or the defendant's state when the complaint names it. Tracking: the defendant's state, because about three in four are filed in California courts against companies located anywhere.
Industry
Rule
From the defendant's name and, when available, the complaint, mapped to one of twenty groups. Unclassified cases count in totals but not on industry pages.
Plaintiff firm
Rule
The firm listed for the plaintiff on the docket, normalized so spelling variants merge. Known defense firms are never counted as plaintiff firms.
Tracking script
Rule
A case is linked to a script when the complaint text names it. Complaints not yet in the public record are not linked, so tracker counts are a floor.
Window
Rule
By filing date: last 30 days, last 90 days, last 12 months, all in UTC. Where records for a theory start inside a window, pages say since when.

03Limitations

Federal coverage depends on what PACER feeds publish to CourtListener. Attorney and firm fields can arrive days after filing and are refreshed for two weeks.
State-court coverage is partial: only filings with a public source Suitcast reads are included, so California state CIPA cases in particular are undercounted.
Verification favors precision over recall. A website case whose docket text lacks web terms, and whose firm is not yet on the list, waits in a review queue and is not counted until reviewed.
Counts describe filings, not outcomes. Nothing here says a claim succeeded.
CourtListener, run by the Free Law Project, supplies the federal court records. The counts, the verification and the classification are Suitcast's own work and are not produced, reviewed or endorsed by the Free Law Project.
Illinois accessibility filings fall sharply after June 2026. The largest filer there, Equal Access Law Group, has filed no website case since June 3, 2026 in any court it used before, while other firms kept filing in the Northern District of Illinois. The drop reflects that firm stopping, not missing records.

Counts include federal filings from CourtListener and curated state filings with sources. State-court coverage is partial.

04Update cadence

Federal records are pulled every morning at 06:00 UTC, complaint texts through the day, and the public pages rebuild daily. This page and the JSON refresh hourly. Methodology changes are dated in the changelog.

05Changelog

September 14, 2026: Twelve months of federal accessibility filings added, so every window now covers its full period. A complaint is linked to an accessibility issue only when it alleges that barrier against the defendant, not when it describes accessibility barriers in general.
September 13, 2026: Count windows now say since when a theory's records start, where that is inside the window, instead of a window the data does not yet cover.
September 12, 2026: Dataset launched with 12 months of federal tracking filings. Criminal pen-register dockets and appellate courts excluded from the tracking query. Defense firms excluded from firm rankings.
