frp (Fast Reverse Proxy) is an open-source, self‑hosted solution that enables developers and IT professionals to expose local services to the internet securely. It works across Web, Windows, macOS, and Linux, providing flexible TCP, UDP, HTTP, and HTTPS tunneling. Designed for simplicity and performance, frp lets you configure proxy rules via a lightweight client‑server model, making it ideal for remote debugging, IoT device access, and internal tool exposure without complex VPN setups.
SRS (Simple Realtime Server) is a high-efficiency open-source media server for live video. It ingests and delivers streams over RTMP, WebRTC, HLS, HTTP-FLV, HTTP-TS, SRT, MPEG-DASH and GB28181, with codec support for H.264, H.265, AV1, VP9, AAC, Opus and G.711. The server is highly configurable, clusters well for large audiences, and integrates with existing workflows through its broad protocol support.

The Verdict
AI-generated from listing dataBoth tools are free, open‑source, and self‑hosted, but frp is a general‑purpose reverse‑proxy/NAT traversal solution, while SRS is a specialized real‑time video streaming server.
Key differences
- •Primary use‑case: frp proxies any TCP/UDP service; SRS handles video ingest, transcoding, and delivery.
- •Protocol support: frp offers generic TCP/UDP with TLS; SRS supports RTMP, WebRTC, HLS, SRT, GB28181, HTTP‑FLV.
- •Built‑in media features: SRS includes live transcoding, adaptive bitrate, and clustering for video; frp does not.
- •Configuration focus: frp uses simple INI files; SRS relies on more complex config for streaming pipelines.
- •Community focus: frp’s audience is developers/IT; SRS targets media professionals and streaming engineers.
Pricing & value
Both are free, open‑source with no licensing cost.
Ease of use / learning curve
frp uses simple INI‑style files and runs on all OSes; SRS config is more complex for streaming pipelines.
Features & depth
SRS provides extensive video‑specific features (transcoding, WebRTC, HLS, SRT, GB28181) not present in frp.
Integrations & ecosystem
frp’s generic proxy model integrates with any service; SRS is limited to media‑related integrations.
Scalability
SRS includes built‑in load‑balancing, clustering, and health checks for thousands of viewers; frp offers basic load‑balancing.
Support
frp lists email support plus GitHub Issues; SRS only lists GitHub Issues and community forum.
Security & privacy
frp provides built‑in TLS encryption for any proxied traffic; SRS relies on protocol‑level security (e.g., SRT) but no universal TLS.
Choose frp if…
Developers needing a simple, OS‑agnostic reverse proxy for arbitrary services.
Choose SRS if…
Media teams requiring real‑time video ingest, transcoding, and multi‑protocol streaming.
Common questions
Is there any cost to use either product?
Both frp and SRS are free and open‑source.
Can I use frp to stream live video?
frp is a generic proxy and does not provide video‑specific features like transcoding or WebRTC.
Which tool scales better for thousands of concurrent connections?
SRS includes built‑in clustering and load‑balancing designed for high‑volume video streaming; frp’s scaling is more limited.
