title: FCL description: Making secure web applications powered by the Flow Blockchain
Flow Client Library (FCL) enables applications to easily integrate with all FCL-compatible wallets and other services (e.g. (Comming Soon) profiles, private information, notifications). This offers developers a strong foundation to compose their apps with existing building blocks. It’s currently supported for browser applications, and will be extended to other platforms.
With FCL, you can:
- Integrate all compatible wallets without any custom code or code injection
- Authenticate users
- Query the Flow Blockchain
- Send transactions (e.g. initializing resources, sending assets, purchasing, etc.)
- Sign transactions through wallet integration avoiding key management
With FCL, you will eventually be able to:
- Personally sign data via FCL Compatible Wallets
- Request Additional User info like Emails
