I will build a lightweight browser app optimized for around 1 mb
Seondong Lee
About this gig
I build lightweight browser apps optimized for one practical task, such as a calculator, checklist or input tool. I use AI to assist development and review the result.
The $80 package includes one responsive screen, one core feature, HTML/CSS/JavaScript source, run instructions, 3-day delivery and one revision.
We target around 1 MB (1,000,000 bytes): the combined uncompressed runtime files, including code, images, icons and fonts. Documentation and development-only files are excluded. I avoid unnecessary dependencies and provide a file-size breakdown at delivery. External CDNs are not used to hide assets from the count.
Before ordering, we confirm the feature, required assets, target browser and size-target feasibility through Fiverr. File size alone does not guarantee speed or memory use.
Reproducible errors in the agreed environment are fixed for 7 days after delivery, separately from the revision.
Native Android apps, login, payments, servers, databases, external APIs and hosting need a separate quote. All work is remote; communication and delivery stay on Fiverr, primarily in written English.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

FAQ
Can this include Android apps, login or a backend?
The $80 package is a browser app with one screen and one core feature. Native apps, login, payments, servers, databases and external APIs require a separate quote.
How are revisions and bug fixes handled?
One revision within the agreed scope is included. Errors reproducible in the agreed environment are fixed for 7 days after delivery, separately from that revision. New features or changed requirements need a separate scope.
Is hosting included?
No. I deliver source files and run instructions. Hosting, deployment and ongoing operation are outside the base package and need a separate quote.
