I built TgCloud: An open‑source image hosting & CDN powered by Telegram storage

说明与用途

TgCloud 是一个免费图像托管服务，利用 Telegram 作为后端。它通过 API、URL 或 UI 上传图像，然后从 Telegram CDN 代理图像，消除了云存储成本。

问题

Avoid costly AWS S3 bills and rate‑limited public APIs for basic image storage.

结果

TgCloud provides a zero‑cost, hotlink‑friendly image hosting service using Telegram’s unlimited storage, suitable for personal portfolios and small side projects.

工作流

• Clone the TgCloud repo
• Create a .env file with BOT_TOKEN, CHAT_ID, and PORT
• Run the binary (go run main.go)
• Upload images via API, remote URL, or drag‑and‑drop UI
• TgCloud streams the image to a Telegram channel and receives a File ID
• TgCloud proxies the image from Telegram’s CDN to the requester via https://your‑vps.com/img/{id}

证据

I built TgCloud. It requires absolutely no database.

来源

Upload: You POST your image (file or remote URL) to the TgCloud binary.

来源

Stream & Store: TgCloud securely streams it to your private Telegram channel using the native Telegram Bot API.

来源

Proxy & Serve: When someone requests https://your-vps.com/img/{id}, TgCloud fetches the raw data from Telegram's CDN and proxies it directly back to the user.

来源

Rate Limits: Telegram limits Bot API traffic to roughly ~30 requests per minute.
