What OOPSpam does
OOPSpam operates a server-side spam and fraud detection API for websites, forms, and email submissions. Its core product is an ML-powered REST API that performs context-aware spam classification, supplemented by a Domain Reputation API backed by a daily-updated database of malicious email addresses and IPs. The system is designed to run entirely on the server, requiring no client-side JavaScript, fonts, or CSS, and to maintain accuracy without storing customer data, which positions the offering as GDPR compliant and accessible (no CAPTCHAs).
The company distributes through a product-led growth model with official plugins and integrations for WordPress, WooCommerce, Bubble.io, Zapier, Make, ActiveCampaign, EmailOctopus, and several form builders including Contact Form 7, Gravity Forms, Ninja Forms, and Elementor Forms. OOPSpam LLC is a privately held, bootstrapped company founded in 2017 and headquartered in Minneapolis, Minnesota, operating with a 1-10 person team.

Revenue is generated exclusively through tiered monthly or annual subscriptions (Starter at $19.17/month annually up to Scale at $215.80/month annually for 1M checks), plus 40 free API calls as a funnel into paid tiers.

OOPSpam competitors and assessment
Company assessmentEmerging players
- SpamAssassin: Open-source Apache spam-filtering engine widely used for email spam detection. Comparable in core spam-detection mission; differs in being open-source/email-centric vs. OOPSpam's commercial form/comment API.
- Arkose Labs: Bot management and online fraud prevention platform serving enterprise customers. Overlaps with OOPSpam on spam/abuse prevention but targets larger accounts and broader fraud use cases.
- CHEQ: Go-to-market security platform that blocks fake form submissions, bots, and fraud. Comparable in targeting form-spam and lead-fraud prevention for marketing and e-commerce teams.
- BotGuard: WordPress-focused bot and spam protection plugin with subscription pricing. Direct niche competitor in the WordPress ecosystem with similar plugin-distribution GTM.
- DataDome: AI-powered bot and fraud management platform protecting websites, apps, and APIs. Comparable in using ML for real-time threat detection but broader in scope than OOPSpam's narrow spam API.
Broad incumbents
- hCaptcha: Privacy-focused CAPTCHA service used as a reCAPTCHA alternative. Broad incumbent with similar go-to-market; OOPSpam names hCaptcha as a key competitor in its comparison content.
- Google reCAPTCHA: Default free CAPTCHA service from Google used across most websites for spam/abuse prevention. The dominant incumbent OOPSpam positions against on privacy and UX grounds.
- Cloudflare Turnstile: Free, privacy-friendly CAPTCHA alternative from Cloudflare that blocks bots without puzzles. Broad incumbent bundled into Cloudflare's network; OOPSpam explicitly competes against it on UX, accessibility, and accessibility-friendly positioning.
Direct peers
- CleanTalk: Cloud-based anti-spam service for websites, comment forms, and sign-ups with subscription pricing. Direct competitor named in OOPSpam's own comparison/alternative marketing pages.
- Akismet: Automattic-owned comment and form spam filtering service widely used on WordPress. Direct competitor that OOPSpam explicitly targets via comparison/alternative pages; both sell subscription APIs for spam detection.
