HTTP/2, HTTP/3 and QUIC implementation
We enable and configure modern transfer protocols: HTTP/2 (multiplexing) and HTTP/3 on QUIC (faster on unstable and mobile networks). So resources load in parallel and with lower latency. Honestly upfront: this gives a real latency win, but requires server/CDN support, and the size of the effect depends on the user's network and the site structure.
HTTP/2, HTTP/3 and QUIC implementation — overview

HTTP/2, HTTP/3 and QUIC implementation is a project: we enable and correctly configure HTTP/2 (one connection, request multiplexing, priorities) and HTTP/3 over QUIC (UDP, faster connection setup and more resilient to packet loss on mobile/unstable networks), with a fallback to older protocols for old clients. Honestly about the conditions, this is key: HTTP/3/QUIC needs support on the server or CDN side (and open UDP/port 443); not all hosting allows this — it is often simpler via a CDN; we honestly check what is possible in your infrastructure. Honestly about the effect: the win is real but NOT universal or fixed — it is more noticeable on mobile/distant/unstable networks and on sites with many resources; on a fast wired connection the difference may be small. The protocol itself does not 'magically speed up the site' — it removes part of the network latency but does not cure heavy content or a slow server (those are separate tasks). Honestly about business: this is part of speed, we do NOT guarantee sales growth by itself. Honestly about access: access to the server/CDN is needed. An important boundary: this is protocol setup, not a full CDN (713 — separate), not content optimization and not application tuning. If you already have HTTP/2 via a CDN and the site is light, the win from HTTP/3 may be modest — we say so honestly. Picture this: instead of sequential loading over the old protocol — parallel transfer with lower latency, especially on mobile. The base price starts from 18,000 ₽ per project; it depends on the server/CDN.
Problems we solve
- The site runs over an outdated protocol (HTTP/1.1).
- Resources load sequentially, with delays.
- On mobile/unstable networks there are noticeable connection lags.
- HTTP/3/QUIC is not set up though the infrastructure allows it.
What's included in the HTTP/2, HTTP/3 and QUIC implementation service
- Enabling and configuring HTTP/2 (multiplexing, priorities)
- Implementing HTTP/3 over QUIC (where supported)
- A fallback to older protocols for compatibility
- Checking server/CDN support and ports (UDP/443)
- Verifying correct operation and certificates
- Measuring the effect (where it manifests)
- A CDN recommendation if needed for HTTP/3
- Handover and review with you
What you get
- Parallel resource transfer (HTTP/2)
- Faster and more resilient connection on mobile (HTTP/3/QUIC)
- Compatibility with old clients (fallback)
- Less network latency (sales growth — not guaranteed)
How the work goes: steps
- We check server/CDN support; collect access
- We enable HTTP/2 and HTTP/3/QUIC with a fallback, verify certificates

FAQ
Will HTTP/3 speed up my site several times over?
Not universally. The win is real but more noticeable on mobile/unstable/distant networks and on sites with many resources; on a fast wired connection the difference may be small. The protocol removes part of the network latency but does not cure heavy content or a slow server.
Will HTTP/3 definitely work for me?
It needs server or CDN support and an open UDP/443. Not all hosting allows this — it is often simpler via a CDN. We honestly check your infrastructure and say what is realistically configurable.
Will it raise sales?
Not directly guaranteed. It is part of speed (less network latency), useful for UX, but sales depend on many factors. Heavy content and a slow server are separate tasks.
