For Open Source Contributors
Code you share publicly becomes everyone's attack surface.
We scan, then we forget. You keep what you want.
A snippet in a discussion thread, a merged pull request, a tagged release — on GitHub, code does not stay where you put it. It gets forked, copied into other projects, and run on machines you will never see. A vulnerability you ship once can propagate into thousands of downstream repos before anyone files an issue. AllScanTool gives you a fast, private check before you publish: paste your source and the Delivery-Layer Engine flags SQL injection, XSS, hardcoded credentials, and insecure functions, then forgets it. It runs in your browser, and your code never leaves your machine. No logs. No storage. No retention. Your code stays private.
Public code travels further than you think
The reach that makes open source powerful is the same reach that turns a single mistake into a widespread one. These are the moments worth a scan first.
A flaw you ship gets forked everywhere
Once a repo is forked and vendored into other projects, a vulnerability in your code lives on in copies you cannot patch or even find.
Discussion snippets get pasted into production
Code shared to answer a thread is read as a recommendation. Developers drop it straight into real projects, insecure parts and all.
Drive-by contributions are hard to fully vet
As a maintainer you review many PRs from people you do not know. A subtle injectable query or unsafe call can slip past a busy review.
Example code sets the pattern others copy
READMEs and sample folders are the most copied code in any repo. If the example concatenates a query, that becomes the de facto standard downstream.
Secrets get committed to public history
A test token left in a commit is exposed the moment you push, and git history keeps it long after you delete the line.
You are the security team for your project
Most open source is maintained by volunteers without an AppSec function. A fast, private scan is a realistic gate before you tag a release.
Ask AST
The questions maintainers and contributors ask before code goes public — answered.
QI'm about to tag a release — how do I check the code before thousands of people pull it?
Paste the source you are shipping. AST scans for SQL injection, XSS, insecure functions, and hardcoded secrets and reports each with its line and a fix, so you can clear the high-risk findings before you publish the tag.
QA contributor opened a PR with a database query — is it injectable before I merge?
Drop the diff in. If the query builds SQL from string concatenation with user input, AST flags it and shows the parameterized version, so you can review the security of an unfamiliar contribution quickly.
QI'm posting a snippet in a discussion — how do I make sure I'm not recommending something unsafe?
Paste it before you hit comment. AST checks the snippet for the patterns people will copy verbatim — unescaped output, unsafe calls, concatenated queries — so your answer does not propagate a vulnerability.
QBefore I open-source this repo, how do I know there are no credentials in the code?
Run your source through AST. It detects hardcoded keys, tokens, and passwords in the files and shows where they are, so you can move them to environment variables before the code — and its history — goes public.
