Product Introduction

1. Sarv is a developer tool that enables instant and secure sharing of local web applications through public URLs accessible over the internet. It eliminates the need for complex deployments by creating tunnels between local servers and a custom subdomain, allowing external access to development environments.
2. The core value of Sarv lies in its ability to simplify collaboration and testing by providing zero-configuration, SSL-secured public URLs for localhost servers. It bridges the gap between local development and real-world testing while maintaining security and accessibility for distributed teams.

Main Features

1. Sarv provides custom subdomains that users can personalize (e.g., myapp.sarv.live) to share local servers with branded URLs. These subdomains remain persistent and can be managed through the web dashboard without requiring DNS configuration.
2. Automatic SSL certificates are included for all tunnels, ensuring HTTPS encryption for secure data transmission. This feature eliminates manual certificate generation and renewal, providing end-to-end encryption through Sarv’s infrastructure.
3. Multi-port support allows exposing multiple local ports under a single subdomain using path-based routing. For example, api.sarv.live/backend can map to port 8080 while api.sarv.live/frontend routes to port 3000, simplifying complex project setups.

Problems Solved

1. Sarv addresses the challenge of securely sharing local development environments without deploying to staging servers or exposing raw IP addresses. It removes dependencies on third-party hosting platforms during early development phases.
2. The tool targets developers, QA teams, and freelancers who need to demo projects, test webhooks, or collaborate on local APIs. It is particularly useful for remote teams requiring real-time access to in-progress work.
3. Typical scenarios include testing mobile apps against local APIs, debugging webhooks with external services like payment gateways, and presenting unfinished websites to clients for feedback before deployment.

Unique Advantages

1. Unlike competitors with usage limits or paid tiers, Sarv operates as a 100% free service with no hidden costs, credit card requirements, or feature restrictions. This distinguishes it from freemium models common in similar tools.
2. The integration of a web dashboard for tunnel management enables centralized control over subdomains, ports, and traffic monitoring—a feature often limited to desktop apps in alternative solutions.
3. Competitive advantages include instant SSL provisioning, support for simultaneous multi-port exposure under one domain, and infrastructure optimized for low-latency connections, ensuring reliable performance for development workflows.

Frequently Asked Questions (FAQ)

1. Is it really 100% free? Sarv is completely free with no usage limits, premium tiers, or hidden fees, as it operates through cost-efficient infrastructure and aims to support developer communities without monetization barriers.
2. How secure is the connection? All traffic is encrypted with TLS 1.3 via automatically provisioned SSL certificates, and while data passes through Sarv’s servers, end-to-end encryption ensures third parties cannot intercept sensitive information.
3. How do I set up my local server? After account creation, users download a lightweight client, authenticate via the dashboard, and configure tunnels by selecting a subdomain and local port—no command-line expertise or firewall adjustments are required.
4. Can I use it for production websites? Sarv is designed for development and testing, not production workloads, as it lacks scalability features and SLA-backed uptime guarantees required for commercial deployments.
5. How do you offer this for free? The service maintains affordability through optimized routing algorithms and lightweight infrastructure, avoiding the overhead costs that typically necessitate subscription models in similar tools.
