What you get
Cross-bucket search
One query, every bucket you have access to — results come back grouped by bucket name, not scattered across tabs.
Favorite buckets
Pin the ones you use daily, one click away.
Read-only, always
Never uploads, deletes, or modifies a file.
Lives in your browser
No backend — nothing leaves Chrome but your AWS calls.
Built to earn trust, not just installs
Least-privilege by design
BucketFinder only ever asks for s3:ListAllMyBuckets, s3:ListBucket, and s3:GetObject. No write or delete permissions, ever.
No backend, ever
Every request goes straight from your browser to AWS using your own credentials. We never see or store your keys or your data.
Open about the limits
BucketFinder can only see buckets your IAM user can list. Very large accounts may take a few seconds longer per search.
Frequently asked questions
No — and you shouldn't. BucketFinder works with a scoped-down IAM user or role. We recommend creating a read-only IAM user specifically for it, so it can never do more than list and read.
s3:ListAllMyBuckets, s3:ListBucket, and s3:GetObject (only if you want to open files directly). That's the full list — nothing else is required.
No. There's no backend. Your credentials are stored locally in your browser and used to call AWS directly — nothing is proxied through or logged on our servers.
BucketFinder is a Chrome extension, and works on any Chromium-based browser, including Chrome, Edge, and Brave.
The AWS Console only searches one bucket at a time, in one tab. BucketFinder searches across every bucket your credentials can see, in a single query, with results grouped by bucket.
After your 7-day trial, BucketFinder continues as a low-cost monthly subscription. No long-term commitment — cancel anytime.
Yes. Anywhere you can supply valid IAM or STS credentials — including roles assumed through AWS SSO — BucketFinder can search against that account.
