On May 11, 2015, the site was renamed from "SourceForge.JP" to "OSDN".{{cite web

In contrast, OSDN totally refuses adware bundling and project hijacking.{{cite web

On February 26, 2020, it was announced on the site that OSDN was being transferred to Appirits, Inc., a Japanese software company.{{cite web |author=Shuji Saito |url=https://osdn.net/projects/docs-en/news/26194 |title="OSDN Business is Transferred to Appirits |language=en |access-date=2024-02-06}}

Open Source China (OSChina) announced on 24 July 2023 that they had acquired OSDN in 2022.{{cite web |author=Open Source China |url=https://www.oschina.net/news/250642/oschina-acquired-osdn |title=开源中国收购日本老牌开源社区 OSDN |language=zh |date=2023-07-24 |access-date=2024-02-07}} The site had reliability problems almost immediately after this announcement,{{cite web |author=Matthew Skala |url=https://tsukurimashou.org/osdn.php.en |title=What's up with OSDN? |publisher=Tsukurimashou Project |date=2024-02-07 | access-date=2024-02-07}} and there was an effort by SourceForge (the original, American-based site) to recruit projects that might choose to leave OSDN; especially those using SVN, which would be unsupported on GitHub.{{cite web |author=impress |url=https://forest.watch.impress.co.jp/docs/serial/yajiuma/1520801.html |title=接続不調が続く「OSDN」、米「SourceForge」がプロジェクトの勧誘に乗り出す |language=ja |date=2023-08-02 |publisher={{label|Q11287772}} |access-date=2024-02-07}}{{cite web |author=SourceForge Community Team |url=https://sourceforge.net/blog/welcoming-osdn-projects-to-sourceforge/ |title=Welcoming OSDN Projects to SourceForge |date=2023-07-31 |access-date=2024-02-07}} Many projects did leave OSDN, including Vim and TeraTerm.{{cite web |author=Christian Brabandt |url=https://groups.google.com/g/vim_announce/c/itcFF4DNj4A/m/KtoZKBrcBgAJ |title=Moving the Vim Homepage (vim-announce mailing list) |publisher=Google Groups |date=2023-09-21 |access-date=2024-02-07}}

ITmedia NEWS reported on January 22, 2024 that OSDN had announced they would shut down the associated Slashdot Japan-successor site (Surado) at the end of January 2024.{{cite web |author=ITmedia NEWS |url=https://www.itmedia.co.jp/news/articles/2401/22/news118.html |title=スラド終了 「スラッシュドットジャパン」から23年の歴史に幕 |language=ja |date=2024-01-22 |access-date=2024-02-06}} However, articles in ITmedia NEWS and Surado at the end of January reported that the closure of both sites had been cancelled and OSChina now hoped to keep them in operation while seeking acquirers to take them over.{{cite web |author=headless |url=https://srad.jp/story/24/01/31/1253207/ |publisher=Surado |title=スラドとOSDN、閉鎖せず受け入れ先募集へ |language=ja |date=2024-01-31 |access-date=2024-02-07}}{{cite web |author=ITmedia NEWS |url=https://www.itmedia.co.jp/news/articles/2402/01/news118.html |title=「スラド」閉鎖を撤回 受け入れ先を募集中 |language=ja |date=2024-02-01 |access-date=2024-02-06}}

Nonetheless, as of early 2025, the OSDN.net web-site is no longer reachable for the public.https://www.isitdownrightnow.com/osdn.net.html

OSDN provides revision control systems such as CVS, SVN, Git, Mercurial, and every feature in SourceForge. What makes OSDN different from SourceForge is the bug tracking system and the wiki system. On OSDN, these are very Trac-like systems.{{cite web |url=https://osdn.net/projects/cabos/ticket |title=Cabos Project Tickets |access-date=2016-10-28}}
