Base44 Client Portal Guide (2026): Cost, Login and Security

Base44 client portal guide 2026: Plan secure logins, client-specific permissions, file sharing, realistic plan costs and testing before launching a portal with sensitive customer information.

What should a basic client portal actually do?
Start small. A useful first version could let a consultant invite a client, display the status of that client’s projects, collect an intake request and share approved documents. It should not need a public-facing chat agent, payments, complex billing or dozens of integrations on day one.
| Module | Minimum useful function | Critical security question |
|---|---|---|
| Accounts | Invite users and require sign-in | Can an unknown person access any page or record? |
| Projects | Display client-specific project status | Can Client A see Client B’s projects? |
| Requests | Submit a service request | Can users change someone else’s request? |
| Documents | Share approved files | Are underlying download URLs appropriately protected? |
| Admin area | Review and update requests | Can a client gain admin capabilities? |
Base44’s free plan and likely costs
Base44’s October 2026 pricing page advertises a Free plan with 25 message credits per month, 100 integration credits per month and up to five apps. It lists authentication and a database among core functionality. Message credits are for AI-assisted building; integration credits support certain live-app actions. A busy portal with automated messages or external-service calls may need more capacity.
Its publicly listed paid prices with annual billing start at approximately $16/month equivalent for Starter, $40 for Builder and $80 for Pro. A monthly billing choice may cost more. Additional services such as email, payment processing or external AI APIs can have separate costs.
Credit usage, included integrations and premium security features matter as much as the headline subscription. Test with non-sensitive sample data first.

Step 1: Write a precise portal specification
An AI builder works best when the request is specific. An example prompt could be:
Design a private client-request portal for a small consulting business. Each client signs in and sees only their own projects, tickets and shared files. An admin can review all assigned requests. Create accessible mobile layouts. Do not permit client-to-client data access; use server-enforced row-level permissions. Do not include real customer records or payments in the prototype.
This is a starting specification, not a guarantee that the builder will implement security correctly. Require a data model and an explicit access-control review before declaring the work complete.
Step 2: Plan your data tables and ownership fields
A minimal design might use Clients, Projects, Requests and Documents. Each record should have a reliable owner or organization identifier; do not depend on a visible display name to control authorization.
For example, a request might contain an ID, client account ID, status, created date and description. The primary authorization question is whether the server checks ownership before returning the request—not merely whether the frontend hides other clients from the menu.
Step 3: Turn on the right visibility and authentication
Base44’s application-security guide describes Private and Public with login required visibility models. For a limited invited-client group, Private may suit the first test. A broader customer portal may require a login-gated public app, but that setting alone is not sufficient to protect individual records.
Use the built-in authentication and role system instead of creating a custom password field. Base44’s documentation distinguishes role-based restrictions from app visibility; both need appropriate configuration.
Step 4: Test row-level and field-level permissions
Row-Level Security (RLS) defines which records a user can read, create, edit or delete. Field-level protections add restrictions on particular sensitive fields. An example policy might allow a client to read their own requests while allowing only an assigned staff member to update request status.
Run at least these tests with dummy accounts:
- Create Client A and Client B; give each a separate test request.
- Sign in as A and open A’s request normally.
- Manually attempt to open B’s request by entering a direct link or altering an ID.
- Attempt to query B’s records through any available app interfaces or API flows, not just the navigation menu.
- Try editing an admin-only field and deleting another user’s record.
- Repeat the tests after the AI builder modifies the data model or interface.
The expected result: Server-side authorization should deny access, even when someone manipulates an identifier. A failure here is a launch blocker. This is not a test that BigExclusives performed on a real app; it is a test plan readers should complete themselves.
Step 5: Secure file sharing and external connections
File uploads need validation, access controls and retention rules. A private page does not prove a document’s underlying storage URL is private. Test the download as an unauthorized user and after access has been revoked. Never put confidential data into AI prompts or public error logs without understanding the provider’s privacy policy and contractual commitments.
Base44 states that it encrypts data in transit and at rest and provides additional workspace and sign-in controls on certain plans. These vendor claims do not replace an assessment of your own app. Review the official Base44 security overview and your data-protection requirements before real client use.
Step 6: Add practical features only after the core workflow works
Features such as email notifications, document approvals, external calendars and payments may require connected services and additional credits. Start with the simplest flow that solves a real problem. Monitor which actions incur integration usage; the free plan may be suitable for a demo but not necessarily a heavily used production portal.
Plan an export and recovery path. “I can download code” and “I can reconstruct my application and client data elsewhere with matching authorization” are different claims. Test backups and migration against real requirements before signing a long-term contract.
Base44 client portal: launch checklist
- Invitation and account recovery work with test users.
- Clients cannot view other clients’ records.
- Admin privileges cannot be reached from the client role.
- Files are not exposed through unprotected URLs.
- Invalid input and unexpected errors are handled safely.
- Mobile and keyboard navigation support the main workflow.
- Backups, exports, billing limits and incident contacts are documented.
- Privacy notice, access rights and retention requirements fit the business.

Frequently asked questions
Can I make a Base44 portal free?
The Free plan provides core building features and limited credits, but the suitability for a live portal depends on integrations, usage and security requirements.
Is a login screen enough to protect client data?
No. Each data operation must enforce who can read or change particular records.
Does Base44 provide a database?
Yes, the provider lists integrated data and authentication features among its plans. You still need to define records and permissions correctly.
Should a regulated business use it immediately?
No. Review contractual, security, residency, audit and legal requirements with appropriate professionals and verify compliance controls before uploading sensitive information.
Who should consider Base44?
It can be useful for a small team prototyping a process, provided the team can run permission tests and handle data responsibly. It may be less appropriate where extensive custom infrastructure, strict regulatory obligations or unusually complex authorization require a separately engineered solution. Keep a clear acceptance checklist and stop before production if data isolation fails.
