IS FILLVISA OS A LOLLYLAW ALTERNATIVE?
For immigration form preparation, yes.
For your entire practice, compare the scope.
Fillvisa OS is a 100% free, self-hostable, AGPL-3.0 alternative for the supported immigration form-preparation part of a LollyLaw workflow. It gives you browser-based tools and public source code. It does not replace LollyLaw’s full practice management platform.
LollyLaw combines immigration forms, case workflows, billing, and client collaboration. Fillvisa OS can be useful when you want a standalone form tool and already handle those responsibilities elsewhere. Fillvisa OS documentation · LollyLaw features overview
CHOOSE THE SCOPE YOU NEED
Sometimes the right tool
has a smaller job to do.
If your immediate need is to prepare supported immigration forms, you may prefer a focused tool over adopting a broader platform. Fillvisa OS keeps that choice open.
A focused form experience
Readable questions and clear sections keep attention on the preparation task. Try the same sample form in your current workflow and the Fillvisa demo.
Control over your copy
Inspect the public code, choose your deployment, and adapt the project under its license. Self-hosting lets you operate the form tool yourself.
Fit matters more than feature count. A smaller scope can be useful if you do not need the surrounding platform. It creates gaps if you do. Our design perspective is not a measured claim that LollyLaw is harder to use.

FILLVISA OS MAY FIT WHEN
You want focused tools you can own.
- Your required forms are supported in the release you choose.
- You want to remove the form tool’s software license fee.
- You value public source and optional self-hosting.
- Your existing process covers case tracking and client communication.
- You can maintain your deployment and preserve local work.
LOLLYLAW MAY FIT WHEN
Your team needs connected case operations.
If client questionnaires, collaborative forms, task assignments, and billing need to stay together, evaluate the broader platform on those requirements.
You can also assess Fillvisa OS for a separate preparation task while keeping your existing case system. Plan the handoff yourself; this is not a claim of an integration.
SELF-HOSTABLE. AGPL-3.0 LICENSED.
Your copy. Your deployment. Public source.
Fillvisa OS is a static frontend. The open-source core does not require a backend. Start with the repository instructions and verify your deployment before using it for real work.
01 / GET THE CODE
Start with the project.
Choose a repository release, review its included forms and documentation, and keep a record of the version you deploy.
View the repository →02 / HOST YOUR COPY
Serve the static files.
Use a static web server and test the form workflow, asset loading, downloads, and saved progress. Your deployment remains your responsibility.
Read setup documentation →03 / UNDERSTAND THE LICENSE
Built on AGPL-3.0.
Review the license before adapting, distributing, or operating a modified version for others. The repository’s license text is the authoritative reference.
Read the license →Control comes with responsibility. Plan updates, access controls, device security, and backups. Self-hosting a static frontend does not create a shared client database or cloud sync. Source availability alone is not a security certification.
SWITCH WITH A CLEAR PLAN
Test the fit before moving active work.
Start with one complete preparation workflow. Keep your existing process available until you know what the open-source edition covers.
Inventory your actual requirements
List forms, outputs, client communication, deadlines, billing records, accounting, and staff access. Identify which tasks can move to a form tool and which must remain in a practice management system.
Run a representative sample
Use fictional information to test a typical form and an edge case. Review the exported output and saved-progress behavior, including what happens when you close and reopen the browser.
Check exports and records
Confirm LollyLaw’s export options and preserve your source records. Test only supported imports. Matter relationships, documents, notes, calendars, and financial records require separate handling; form answers do not recreate a practice database.
Prepare your deployment
Assign responsibility for hosting, updates, access, and backups. Document how users preserve local work and where completed files are stored.
Decide what stays and what moves
Compare the full operational cost and effort. Keep any tools you still need, and verify records and workflows before cancelling an existing service.
