Grit Git rewrite in Rust
Ranked 3 of 4 Git implementations by recommenders
Recommended as a memory-safe Rust library for Git-based tools under a permissive license. Critics call it incomplete and say relicensing GPL code is bad faith.

Library for building Git tools
“This isn't for the person using Git. This is for someone trying to build a tool that wants to use parts of Git”

Relicensing GPL code is bad faith
“building on a GPL3 project's complete test suite and relicensing under MIT is not acting in good faith toward the original authors”
Comment from 9 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “showing them exactly how you treat other people's code/licenses by "deciding" to not carry forward the GPL license”
Comment from 9 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “The intent here is extraction of all the value provided by copyleft projects without the obligation to give back.”

AI used for copyright laundering
“ask a robot to recreate your favorite software just so you can relicense it for your business venture”
Comment from 9 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “Assuming the current claims here, that would just be license washing with volunteer assistance.”
Comment from 10 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “It burns a lot of goodwill to use an AI for what many people will see as copyright laundering”

Slower, incomplete, untested, buggy
“It almost certainly cheated on a bunch of those tests and is not feature complete yet.”
Comment from 10 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “It's slower, more obtuse, more bloated, less capable, exponentially less scalable at any size.”
Comment from 10 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “A slower, untested, incomplete git implementation, all for the low low price of $10-$15,000.”
Comment from 10 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” Costly AI tokens, rising prices
“So it is not entire then but somehow that was worth burning $8,000~ dollars worth of tokens?”
Comment from 9 Jun 2026 in “Grit: Rewriting Git in Rust with Agents” “That $15k is indeed a very low low subsidized AI price. It will be $150k next year.”

“That $15k is indeed a very low low subsidized AI price. It will be $150k next year.”
“Of course it has the MIT license, when the original was GPL. To hell with these Rust rewrites!”
“that's all based on your own opinion which appears to ignore the benefits and intent of licenses such as the GPL”
“even if a result is the wholesale looting of open source”
“the source code looks like a steaming pile of crate-includes”
“I won't touch relicensed code even if you payed me.”
“I have to admit they are impressive”
“It burns a lot of goodwill to use an AI for what many people will see as copyright laundering”
“they have such a problem with the GPL that they think it's important to rewrite and relicense”
“this has achieved exactly nothing except lighting $8k on fire”
“Does the OP want us to convert his AI-vibed code to a WASM-compatible build?”
“Why is it everyone else's job to figure out if you're compliant with the license?”
“Assuming the current claims here, that would just be license washing with volunteer assistance.”
“We think it's worth exploring and investing in both options for now.”
“This is simply plagiarism of GPL-licensed code, and license-washing as well.”
“any other app/lib working with that store will always be a suboptimal fit”
“rewrites just like forks (1) are fundamentally an asocial (2) activity”
“The intent here is extraction of all the value provided by copyleft projects without the obligation to give back.”
“It's slower, more obtuse, more bloated, less capable, exponentially less scalable at any size.”
“we went with whatever was the most permissive so everyone could use it for anything if they wish”
“launder the git license and set themselves up for a bait and switch later down the line”
“It almost certainly cheated on a bunch of those tests and is not feature complete yet.”
“feature complete (even if sloppy) library implementation of Git”
“This isn't for the person using Git. This is for someone trying to build a tool that wants to use parts of Git”
“it's memory safe. Not that git has any important memory issue”
“he chose MIT, which cuts at the core of the intent of licensing the project with a share-alike license.”
“A slower, untested, incomplete git implementation, all for the low low price of $10-$15,000.”
“ask a robot to recreate your favorite software just so you can relicense it for your business venture”
“it has been nearly entirely written by agents and has not been used for realsies”
“showing them exactly how you treat other people's code/licenses by "deciding" to not carry forward the GPL license”
“You cannot rewrite git into a linkable library and decide it's now not unix.”
“building on a GPL3 project's complete test suite and relicensing under MIT is not acting in good faith toward the original authors”
“they "decided" it's not a derivative and thus can be listened under MIT instead of GPL”
“all of this is (theoretically) currently covered in Grit.”
“Given the author already admitted that the implementation was slow anyway”
“So .7% tests fail therefor it was 100% a waste of time?”
“So it is not entire then but somehow that was worth burning $8,000~ dollars worth of tokens?”
“There are a number of studies that show that Grit is either not a thing or there are better measures of success.”
“I liked their approach (just had a very buggy transformer/language)”
“the first two works are basically in the “pop-science/self-help woo” category”
