4 Best VirusTotal API Alternatives & Competitors

1. GitGuardian

Anti-Malware, Security, Development Tools

GitGuardian is a developer security platform specializing in automated detection of secrets — API keys, tokens, passwords, private keys, and other sensitive credentials — that are accidentally committed to Git repositories. Every day, developers worldwide inadvertently push sensitive credentials to GitHub, GitLab, Bitbucket, and other Git hosts. Once a secret appears in a public repository, it can be discovered and exploited within seconds by automated scanners. GitGuardian addresses this risk by scanning commits in real time and alerting developers before secrets are exploited, while also enabling retrospective scanning of existing repository history to find previously leaked secrets. Nigerian development teams face this risk acutely. Nigerian fintech companies use numerous third-party payment APIs (Paystack, Flutterwave, Interswitch), banking APIs, SMS providers, and cloud services — all of which issue API keys and secrets that, if leaked, could result in fraudulent transactions, data breaches, or significant financial losses. The fast-moving pace of Nigerian startup development — where shipping speed is prioritized and security reviews may be skipped — increases the risk that a developer accidentally commits a .env file or hardcodes a secret in source code. GitGuardian integrates directly with GitHub, GitLab, and Bitbucket at the organization level. After installation, it monitors every push to every repository in the organization. When a new commit contains what appears to be a secret — matched against GitGuardian's library of over 350 secret detector patterns — an alert is immediately sent to the committing developer and the security team via email, Slack, Jira, or other configured channels. The alert includes the file, line number, commit hash, and remediation steps including instructions for revoking the leaked credential. The 350+ detector patterns cover an enormous range of secrets: AWS access keys, Google Cloud service account keys, Stripe API keys, GitHub personal access tokens, Twilio auth tokens, Sendgrid API keys, Paystack secret keys, SSH private keys, RSA private keys, database connection strings, and hundreds more. Custom patterns can be defined for organization-specific secret formats — useful for Nigerian companies with proprietary API formats. Historical scanning retroactively analyzes the entire commit history of a repository to find secrets committed in the past, even if they were later deleted from the code (deleted files still exist in Git history). Nigerian engineering teams doing security audits or preparing for ISO 27001 certification can use GitGuardian to generate a comprehensive report of all historical secret exposures in their codebase. GitGuardian is free for public and open-source repositories — Nigerian open-source projects and contributors can protect their public GitHub repositories at no cost. For private repositories and team dashboards, the Business plan at $29 per developer per month provides full coverage. The GitGuardian API (dashboard.gitguardian.com/api) allows security teams to programmatically retrieve incidents, manage alerts, and integrate with existing security workflows and SIEM systems. GitGuardian's historical scan capability can scan the full commit history of existing repositories, not just new commits — identifying secrets that were committed in the past and may still be valid or may have been forgotten. Nigerian engineering teams auditing their code security posture for the first time can run historical scans to discover legacy credential exposures that predate their adoption of GitGuardian. The remediation guidance included with each detected secret alert provides specific steps for revoking the exposed credential, rotating it, and updating the codebase to use a secure secrets management approach. This actionable guidance reduces the time from detection to remediation for Nigerian security teams who may not have deep secrets management expertise.

2. Stytch

Development Tools, Anti-Malware

Stytch is a modern authentication platform that specializes in passwordless authentication flows — magic links, OTPs (one-time passwords) via SMS, WhatsApp, email, and phone, passkeys, and OAuth social login — providing Nigerian developers with a comprehensive authentication API that covers the full range of modern login patterns without requiring teams to build authentication infrastructure from scratch. Stytch also provides session management, multi-factor authentication, and B2B authentication (SSO, SCIM) through a unified platform. Nigerian applications face a distinctive authentication challenge: the user population is highly mobile-first, WhatsApp is the dominant communication platform, SMS is near-universally accessible, and passwords are widely considered a poor user experience due to reuse, forgetting, and the inconvenience of password managers. Nigerian fintech and consumer apps benefit enormously from passwordless authentication patterns that reduce friction and improve conversion — a user who can log in with a single SMS code is far more likely to complete onboarding than one who must create and remember a password. Magic links send users a single-use authentication link to their email. When the user clicks the link, they are instantly authenticated in the app without ever entering a password. For Nigerian SaaS and e-commerce applications where users have reliable email access, magic links are the simplest and most frictionless authentication flow available. Stytch's magic link endpoint handles link generation, delivery, verification, and session creation with a few API calls. SMS OTP (one-time password) sends a 6-digit code to the user's phone number via SMS. This is the most familiar authentication pattern for Nigerian users, who regularly receive OTPs from banks, fintech apps, and telecommunications companies. Stytch's SMS OTP supports Nigerian phone numbers in E.164 format (+234...), making it straightforward to authenticate Nigerian users with their mobile numbers. WhatsApp OTP is a unique Stytch capability that delivers authentication codes via WhatsApp rather than traditional SMS. With WhatsApp used by over 80% of Nigerian smartphone users, WhatsApp OTP feels more familiar and accessible than SMS for many Nigerians — particularly for users whose SMS inbox is noisy with promotional messages. This is a significant differentiator for Nigerian consumer apps targeting the mass market. Passkeys (WebAuthn) represent the future of authentication — users authenticate using biometrics (fingerprint, face ID) stored on their device rather than any password or code. For Nigerian mobile apps where users are accustomed to fingerprint authentication in their banking apps, passkey support provides a seamlessly secure login experience. Stytch's passkey implementation handles the complex WebAuthn protocol on the server side, exposing a simple enrollment and authentication API. The free tier supports up to 25 monthly active users — sufficient for development and small-scale testing. Startup plans ($249/month) support production scale for most Nigerian applications in early growth stages. Complete SDKs for React, Next.js, React Native, iOS, and Android simplify frontend integration. Stytch's fraud prevention features include device fingerprinting, IP reputation scoring, and behavioral analysis that identify suspicious authentication activity — account takeover attempts, credential stuffing attacks, and bot-driven registration campaigns. For Nigerian fintech and e-commerce applications that face significant fraud risk, these built-in fraud signals supplement application-level fraud detection without requiring a separate fraud prevention service. The Stytch B2B authentication product extends the platform to enterprise use cases with organization-level user management, just-in-time provisioning, and SCIM directory synchronization. Nigerian B2B SaaS companies building for enterprise clients can use Stytch B2B to implement the enterprise authentication features (SSO, organization management, role-based access) that enterprise procurement teams require.

3. Safe Text Detection API

Utility Tools, Anti-Malware, Content

Safe Text Detection API provides automated content moderation and text safety analysis, enabling platforms to screen user-generated text for harmful content including profanity, hate speech, threats, toxic language, spam, and adult content. The API is designed for platforms that allow users to post text — social networks, comment sections, review systems, chat applications, forums, and marketplaces — where manual moderation is impractical at scale. The analysis engine processes input text through multiple classification models simultaneously, returning a confidence score for each category of harmful content detected. The profanity detection model identifies obscene language across multiple languages and writing styles, including creative misspellings and character substitutions commonly used to evade naive keyword filters. Hate speech detection identifies language that targets individuals or groups based on protected characteristics — race, religion, gender, ethnicity, and nationality — with particular attention to context so that academic discussion of sensitive topics is not incorrectly flagged. Toxicity scoring provides a continuous score from 0.0 to 1.0 indicating the overall harmfulness of the text, allowing platform operators to set custom thresholds for different contexts. A comment section on a general-audience news site might apply a stricter threshold than an adults-only debate forum. This configurability makes the API adaptable to diverse platform policies without requiring developers to maintain separate moderation rulesets. Spam detection identifies promotional content, repeated messages, and solicitations that violate community guidelines. For Nigerian online marketplaces and classifieds sites where spam listings are a persistent problem, the spam detection capability helps maintain listing quality and user trust. The multi-language support is critical for Nigerian platforms where users mix English, Yoruba, Hausa, Igbo, and Nigerian Pidgin in their communications — moderation limited to English only misses a significant portion of potentially harmful content. The real-time API response (typically under 100ms) makes it suitable for pre-publication checks — blocking a comment before it posts rather than requiring after-the-fact removal. Nigerian social platforms, community apps, and user-generated content sites that want to maintain a safe environment can integrate Safe Text Detection into their submission pipeline to automatically hold flagged content for human review or reject it outright based on confidence thresholds. The Safe Text Detection API provides a batch processing endpoint that analyzes multiple text strings in a single API call, reducing round-trip latency for applications that need to moderate multiple items simultaneously — such as moderating all comments on a post when it receives a flood of engagement. For Nigerian platforms that experience sudden spikes in user activity around viral content or breaking news events, batch moderation ensures the system scales to handle peak volumes without creating a moderation backlog. Configurable allow-lists let operators specify words or phrases that should not be flagged despite matching moderation patterns — useful for platforms with specific community contexts where certain terms are used differently than in general discourse. A Nigerian medical health platform might allow clinical terminology that a general content moderation rule would flag. The combination of threshold tuning, category selection, and custom allow-lists gives Nigerian platform operators fine-grained control over the moderation behavior without requiring custom model training.

4. URLhaus API

Anti-Malware, Development Tools, Security

URLhaus is a free threat intelligence API by Abuse.ch that provides access to a community-curated database of malicious URLs used for distributing malware, phishing, and exploit kits. The URLhaus API allows developers and security researchers to query URLs, payloads, and tags — checking whether a URL is flagged as malicious before allowing users to visit or download from it. Security-focused Nigerian developers building browser extensions, email security tools, link shorteners, and web application firewalls use URLhaus to add real-time URL threat intelligence. The API is completely free with no authentication required for basic queries. Supports bulk URL submission for contributing to the community database.
