Frequently Asked Questions
What is Treblle and what does it do?
Treblle is an API observability and governance platform founded in 2020 by Vedran Cindrić and Darko Blaževic in Zagreb, Croatia, backed by $8.42M in funding from Nauta Capital. It integrates with your API via a lightweight SDK or API gateway connector and captures 50+ data points for every request, providing real-time monitoring, 13 automated security checks per request, live auto-generated documentation, compliance scanning (GDPR, PCI DSS, CCPA, HIPAA), and API governance scoring across design, performance, security, and AI readiness dimensions.
How much does Treblle cost?
Treblle's free plan includes 250,000 API requests per month with no credit card required. Beyond the free tier, Treblle offers Starter (for small professional teams), Team (for business-critical APIs), and Enterprise plans, with specific pricing for paid tiers not publicly listed. You can use the full platform for free up to 250,000 monthly requests, and Treblle only asks for payment information when you exceed that threshold. Contact Treblle's sales team for current paid tier pricing.
What are the main features of Treblle?
Treblle's core features include real-time API monitoring with 50+ data points per request, 13 automated security checks (SQL injection, DDoS detection, threat scoring), live auto-generated OpenAPI documentation from actual traffic, API governance scoring across AI readiness, design, performance, and security, compliance monitoring for GDPR, PCI DSS, CCPA, and HIPAA, and Alfred AI assistant for governance remediation guidance. All features activate from a single SDK integration in your existing API code.
Is Treblle free to use?
Yes, Treblle has a free plan that includes 250,000 API requests per month with no credit card required. The free plan provides access to the full monitoring, security scanning, documentation generation, and governance scoring features. For most early-stage startups and small APIs, 250,000 requests per month is sufficient without requiring a paid upgrade. Treblle only requests payment information once usage exceeds the free tier limit.
What are the best alternatives to Treblle?
The main alternatives are Postman (preferred when API testing and team collaboration on request collections is the primary need), Moesif (preferred for B2B API analytics and customer-facing usage metering), ReadMe (preferred for developer portal creation with manual API documentation), and Stoplight (preferred for design-first API development with visual OpenAPI spec editing). Treblle differentiates itself with auto-generated documentation from live traffic and multi-dimensional governance scoring that none of these alternatives provide in a single tool.
Who is Treblle best for?
Treblle is best for backend engineering teams at API-first companies who need real-time production visibility without building custom logging infrastructure, and for platform engineers managing multiple internal APIs who need centralized governance and compliance monitoring. It is particularly strong for companies with GDPR or PCI DSS obligations where automatic sensitive data detection in API traffic is required. It is not well-suited for teams working with GraphQL subscriptions, gRPC, or WebSocket APIs, which Treblle does not currently support.
Does Treblle have an API?
Treblle integrates into your existing API via SDKs available for 20+ frameworks including Node.js (Express, NestJS, Fastify), Python (Django, Flask, FastAPI), PHP (Laravel, Symfony), Java (Spring Boot), .NET Core, Go, and Ruby on Rails. API gateway integrations are available for AWS API Gateway, Azure API Management, Kong, MuleSoft, Traefik, and Cloudflare. Documentation is available at docs.treblle.com with framework-specific quickstart guides for each integration method.
