Douyin_TikTok_Download_API

Douyin_TikTok_Download_API

English | 简体中文

🚀 A self-hosted data API for Douyin and TikTok. One docker compose up, an identity pool that maintains itself, and a REST API, MCP server and web console on top.

Open source, free, and it runs on your own machine — no signup, no quota, nobody else in the path. It fetches posts, authors, comments and search, downloads video and image albums without a watermark (it picks the clean stream the platform already publishes rather than stripping anything), and keeps what it collects in your own PostgreSQL.

🧩 REER — a forum for reverse engineering

<b>reer.dev</b>

Somewhere to put what you work out. This project exists because people wrote down how a signature was built; the forum is for the next round of that — signatures, protocols, packers, anything taken apart.

Free, no advertising, and close to no rules beyond the obvious. Bilingual, English and Chinese. Register and post; nothing is gated.

🎬 What it looks like

One real call: paste a link, send it, get the normalised result back. The identity pool, the scheduler and the API reference it passed through on the way are all in the same console. The interface follows the browser's language, and both are written by hand rather than machine-translated. 中文界面

Try it without installing anything

https://demo.douyin.wtf is a live instance, open to everyone. Sign in — the login page fills the demo account in for you — and use the console: the playground, the scheduler, the library, the API reference. The same account comes with an API key you can call the scraping endpoints with, shown in plaintext on the API keys page.

It is read-only. Demo requests are not written to the request log or the archive, so the database of a public instance cannot be filled by strangers, and switching demo mode off ends every demo session and kills the key immediately.

Rate limit: 30 requests per 10 seconds. Go over it and you are cooled down for 10 seconds, during which every request is refused. It is a shared instance, and the identity pool behind it is the ceiling for everybody using it at once.

What the demo is for is deciding whether to run your own. It is not a service to build on — it can go down, be reset, or be switched off, and none of that will be announced.

🚀 v4 vs v5

v5 is a rewrite. It started from an empty branch and inherits no v4 code.

v4's real problem was never a shortage of features — it was that the API would die quietly and nobody would know. A cookie expires, a signature algorithm changes, an endpoint gets rate-limited, and you find out when someone files an issue. v5 puts "you can see it" and "it heals itself" ahead of features.

	v4	v5
Where identities come from	You copy cookies out of a browser into config.yaml	A headless browser mints guest identities, and the pool tops itself up when usable ones run low
How requests go out	Straight out, as they arrive	Health tiers, quantised LRU rotation, one in-flight lock per identity, a token bucket per (identity, endpoint), a circuit breaker per endpoint
When something breaks	You wait for a bug report	One structured record per request, live health for every identity and endpoint, visible in the console
Call style	Synchronous — send and wait	Asynchronous by default (202 + task_id); add ?wait= to go back to synchronous
What is kept	Nothing; parsed and discarded	PostgreSQL + Redis. Everything parsed is archived, so a post deleted upstream is still here
Access control	None; anyone can call it	API keys with scopes and roles, managed in the console
Interface	A single PyWebIO page	A React console: identity pool, scheduler, library, downloads, logs, diagnostics
Ways in	REST	REST, MCP and a CLI, all over the same service layer
Signing	X-Bogus, A_Bogus	a_bogus, X-Bogus, X-Gnarly, X-Dynosaur in pure Python, with a browser fallback
Deployment	pip install -r requirements.txt + python start.py	docker compose up, three images
Platforms	Douyin, TikTok, Bilibili	Douyin, TikTok

Bilibili is the one thing that went backwards: v5 does not have it yet. It shares neither the signing nor the identity machinery with Douyin and TikTok, so the rewrite left it out for now.

Still on v4?

v4's code stays on the v4 branch, the image is still published, and one command brings it up:

docker run -d --name dtk-v4 --restart unless-stopped \
  -p 8080:80 evil0ctal/douyin_tiktok_download_api:V4.1.2

Then open http://localhost:8080; the API reference is at /docs. Port 8080 is deliberate — v5 binds 8000, so the two versions can run side by side on one machine.

Replace the Douyin cookie before you use it. v4 has no identity pool, and the cookie baked into the image expired long ago, so Douyin endpoints ans
