Cursor cuts Composer 2.5 SDK price 90% for the weekend
Cursor says Composer 2.5 is 90% off in the SDK this weekend. Same-day posts also split between fast one-shot SDK builds and complaints about dropped connections, project controls, and agent follow-through compared with Codex, so test reliability before committing.

TL;DR
- Cursor says Composer 2.5 is ericzakariasson's weekend promo 90% off in the SDK this weekend, and ericzakariasson's SDK post frames the package as the programmatic way to access Composer 2.5.
- Early hands-on posts split fast: bentossell's one-shot build said a Droid SDK came together in about five minutes, while bentossell's repo follow-up said he had not read a line of the generated repo.
- The sharpest critique came from thekitze's Composer 2.5 notes, who said Cursor sometimes lists tasks instead of doing them, drops chat continuity on connection issues, and feels clunkier than Codex on remote work.
- Cursor engaged directly with that complaint, with ericzakariasson's reply asking for request IDs requesting reproducible request IDs and ericzakariasson's follow-up thanking the user for the report.
- The promo is paired with official building material: ericzakariasson's cookbook prompt points people to Cursor's SDK cookbook, and ericzakariasson's SDK post links to the Cursor SDK page.
You can jump straight to the Cursor SDK page, browse the SDK cookbook, and inspect bentossell's generated Droid SDK repo. The interesting split is already visible in the first day of posts: one-shot generation looked good enough for quick SDK scaffolds, while side-by-side comparisons with Codex immediately turned into complaints about orchestration, session reliability, and basic project controls.
Weekend discount
The offer is simple. Cursor says Composer 2.5 is 90% off in the SDK for the weekend, and the same account had promoted @cursor/sdk two days earlier as the way to get programmatic access to Composer 2.5.
That makes this a pricing push around an already-live interface, not a fresh SDK launch. The official entry points in the evidence are the Cursor SDK page and the SDK cookbook.
One-shot builds
The cleanest creation example came from bentossell, who said Composer made a Droid SDK in "like 5 mins" and linked the resulting pi-droid-sdk repo. In the follow-up post, bentossell's repo follow-up added the most revealing detail: he had not read a line of the repo.
That is the best case Cursor wants from a 90%-off weekend, quick disposable builds where the value is the first pass, not careful authorship.
Reliability complaints
The most detailed negative report came from thekitze after a few hours with Composer 2.5. The complaint list was concrete:
- it sometimes says "what you need to do" instead of taking action
- dropped connections can kill chat continuity
- Codex's remote connections felt better than Cursor's SSH flow
- Codex's harness and autocompact felt more trustworthy
- project renaming was missing
- switching to Gemini or Opus inside Cursor still felt like a real advantage
Cursor did not ignore it. In public replies, ericzakariasson's reply asking for request IDs asked for request IDs on the non-executing behavior, and ericzakariasson's follow-up acknowledged the feedback.
Cookbook prompts
After posting the discount, Cursor also asked Grok for ten weekend project ideas and attached the SDK cookbook. That is a different signal from the price cut itself: Cursor is trying to turn the promo into a burst of small public experiments, not just cheaper usage.
The evidence pool only shows one concrete build so far, bentossell's Droid SDK, but the cookbook link means the weekend pitch already has an official prompt-and-example trail for people shipping fast.
