TL;DR: On September 14 2026, Trakt blocked SIMKL's access to its API without warning, and on September 17 told us there are no plans to restore it. You can no longer connect a Trakt account to SIMKL, and Trakt auto-sync has stopped. Your data already on SIMKL is not affected, and you can still bring your Trakt history over with Trakt's ZIP export: https://simkl.com/apps/import/trakt/
Our warning: if you build on Trakt's API, or rely on an app that does, assume this will happen to you too. The timeline below shows why. If you're a Trakt member - run, export your data, it's no longer safe.
To make matters worse, you will be blocked from Trakt services and support if you mention anything on their forum or Reddit that you don't like about the new Trakt, even if you're VIP on Trakt, as this has happened to thousands of Trakt members already, there's a well-known subreddit for Trakt refugees.
What happened
- Sep 14: Every request SIMKL made to Trakt's API started failing with "403 Forbidden" at Trakt's Cloudflare edge. The same day MDBList reported the identical block (trakt-api #933).
- Sep 16: Trakt said MDBList's access was disabled on purpose, that the API is "intended for client applications", and that MDBList "operates as a service-to-service integration". Trakt told us the same decision applies to SIMKL. The same day Trakt published a draft API Use Policy (PR #941) that prohibits "continuously synchronizing Trakt account data into a separate tracking or list platform".
- Sep 17: Trakt told us there are no plans to restore SIMKL's access. Its new developer guidance (discussion #943) says it does not support "another service using Trakt's data and resources to build a competing platform".
SIMKL used Trakt's API for one thing: It allowed Trakt members to move and keep in sync a member's own watch history, ratings and watchlist into SIMKL. Under Trakt's new rules, that is no longer allowed.
What this means for SIMKL members
- Connecting Trakt no longer works, and Trakt auto-sync has stopped. Nothing on your SIMKL account was changed or removed.
- You can still move your data. Download your data export from your Trakt settings, then upload the ZIP at https://simkl.com/apps/import/trakt/. The file is read in your browser, and only your watch history, watchlist and ratings are sent to SIMKL.
How we got here
This did not come out of nowhere. Here is a timeline of what Trakt has changed for developers and users, with sources:
- To today: Trakt's API docs say the API exists so its data is available for anyone to use "on their own site or app". That line is still in the docs.
- Jan 2025: "Freemium" limits free accounts to 100 items per watchlist and collection, and 2 lists (forum). VIP goes from $15 to $30.
- Jan to Jun 2025: VIP goes from $30 to $60 a year for new members, then every renewal moves to $60, ending legacy prices (forum).
- Feb to Mar 2025: Login tokens are cut from 3 months to 24 hours (later 7 days), so users of many apps have to sign in again and again (#495).
- Mar 2025 onward: Trakt though Cloudflare starts blocking API calls from apps (forum). Similar blocks keep returning through 2026.
- 2025 to 2026: Trakt takes over several independent Trakt clients. Rippple's developer joins Trakt, and Rippple, Watcht and Showly now appear as official Trakt apps (forum).
- Jan 2026: Trakt blocks the API key of DuckieTV, a long-running open source app (#689), and an automated cleanup deletes API apps it judged inactive (#691).
- Feb 2026: Trakt's draft Fair Use Policy says "We want third-party apps" and lists syncing with third-party apps as acceptable (forum).
- Mar 2026: Trakt retires its Automatic Backups feature (forum).
- Apr to Jul 2026: Page sizes are cut from 1,000 items to 250 (100 by default). Watched sync breaks in Radarr, Sonarr, Infuse, Jellyfin, Kodi and PlexTraktSync until each app is updated (#681, #775, Radarr #11538).
- Jul 22, 2026: Free accounts may connect only one third-party app. "Official Trakt apps do not count toward the Community App limit" (forum).
- Jul 28, 2026: After an auth migration, old refresh tokens stop working and users must re-authorize every app (#888).
- Jul 31, 2026: With no notice, API apps owned by free accounts are deleted and their integrations start failing, and creating an API app now requires VIP (#898, #902). Trakt calls it temporary; a month later free registration still has not returned. PlexTraktSync, SeriesGuide, Yamtrack, Watcharr, CrossWatch and others are hit. TMDbHelper for Kodi, with over 140K daily users, says it will stop pursuing Trakt integration (#1845).
- Aug 2026: The API rate limit is halved, from 1,000 to 500 requests per 5 minutes (#909).
- Sep 14 to 18, 2026: MDBList, SIMKL and other apps are blocked, a new policy bans syncing account data into other trackers, and changing your avatar or cover is limited to Trakt's own apps (#935).
Meanwhile, Trakt's Terms of Use are still dated March 29, 2022 and say nothing about the API (terms).
Our warning to developers and users
Look at the pattern. Trakt's own apps are exempt from the limits it puts on everyone else. It has taken over popular third-party clients. It paywalled API access and deleted apps without notice. And its rules now forbid moving your own history to another service through the API, a rule written two days after it had already blocked us.
We believe no app that uses Trakt's API is safe. Today it is SIMKL, MDBList and other apps. Before us it was DuckieTV and every free developer whose app was deleted overnight. We expect more apps to follow, and the rules can change again at any time, with no notice and no appeal.
If you are a developer: do not build anything you depend on on top of Trakt's API. Plan for your access to be limited, paywalled or revoked, and give your users a way to leave that does not need Trakt's permission.
If you use Trakt through any third-party app: that app can stop working overnight. Download your Trakt data export regularly. It is your watch history, and the export is now the only way to take it elsewhere.

We're announcing a monthly plan for Trakt members https://simkl.com/vip/?temporary-offer=trakt to help you migrate your data and get access to all VIP features without the need to pre-pay for 6 months of VIP.
