No ability to delete Worker Previews?

[jamestalmage]

According to the docs here, it appears once I upload a worker preview, I cannot delete it? We are in the process of rolling out our own authentication layer in front of our worker previews, and would like to go through and delete old previews so disabling Cloudflare auth doesn't expose previews that predate our own authentication system.

How do I do this? Is my only option to delete the worker entirely?

Issue Triage: #66

Summary

Reporter asks how to delete old Worker preview versions via the Cloudflare API, since previews appear to be non-deletable, and they want to avoid exposing pre-authentication previews once their own auth layer rolls out.

Classification

• Type: Question
• Component: unknown (Cloudflare platform / API, not workers-sdk tooling)
• Severity: N/A
• Has Reproduction: N/A
• Quality: Partial

Findings

• Created: 2026-08-03
• Author: jamestalmage
• Version: not specified
• Labels: none
• Comments: 0 human comments (the only comment on the issue is a prior automated triage report from workers-devprod, not a human response)

Analysis

• The issue is a usage/support question about the Cloudflare API (workers.scripts.versions), not a bug report against Wrangler, Miniflare, or any workers-sdk package. There is no reference to a CLI command, wrangler.json/wrangler.toml, or local dev behavior.
• The underlying concern — whether Worker version previews can be deleted independently of the Worker — is a Cloudflare platform/API capability question. If the API does not expose a deletion endpoint for individual preview versions, that is a platform feature gap, not something fixable in workers-sdk.
• The security angle (previews predating the reporter's own auth layer remaining publicly reachable when Cloudflare auth is disabled) is a real concern, but again relates to platform behavior of preview URLs rather than tooling.
• No reproduction is needed; this is a "how do I..." question with a clear ask.

Recommendation

Status: CLOSE

Reasoning: This is a Cloudflare platform/API question about deleting Worker preview versions, not a bug or feature request in any workers-sdk package. The right venue is Cloudflare Support (or the platform/API team), since deletion of individual preview versions — if unsupported — is an API capability, not a tooling fix.

Action: Redirect the reporter to Cloudflare Support / the community for the platform question, then close as not_planned. If a maintainer knows of a supported deletion path (e.g. via Wrangler versions commands or an API endpoint), share it before closing.

Suggested Labels: none

Suggested Comment

Thanks for the question! This is about the Cloudflare platform/API behavior for Worker preview versions rather than a bug in workers-sdk tooling, so this repo isn't the best place to track it. For questions about deleting preview versions and the security implications of pre-auth previews, please reach out via Cloudflare Support at https://dash.cloudflare.com/?to=/:account/support, or ask on our Discord. I'm going to close this here — if it turns out there's a specific Wrangler/API tooling gap we can address, feel free to open a new issue with details and we'll take a look.

It is not currently possible to hide an individual version from the URL previews.
