Twitter Inc is building a new feature that will allow users to post messages as long as 10,000 characters, Re/code is reporting.

The micro-blogging website, which currently has a 140-character limit, is considering launching the service toward the end of the first quarter but has not set an official date, Re/code reported on Tuesday, citing sources familiar with the plans.

The company, in an attempt to keep a similar look for the timeline, is testing a version of the product which displays 140-character long tweets but expands to reveal more content when clicked on, the technology news website said.

Twitter has been experimenting under Jack Dorsey - the company's co-founder who returned as chief executive in October - to make the website more engaging.

In the few months under Dorsey, Twitter introduced the 'Moments' feature, added polls to tweets, rolled out a "buy" button and replaced its star-shaped "favourite" icon with a heart-shaped icon called "like".

However, some users took to Twitter to express their dissent to the new feature with the hashtag #beyond140.

"Just say no to #beyond140!," Andrew Wright tweeted.

Re/code reported in September that the new feature was in the works.

Twitter declined to comment.
