Redis, a popular in-memory key-value database, is making waves in the tech world once again by returning to its open-source roots. After a few years of fluctuating licensing decisions, Redis has switched from its proprietary licensing model back to an open-source GNU Affero General Public License version 3 (AGPLv3) for Redis 8. However, this move has sparked mixed reactions, with some celebrating the decision and others criticizing it. This article explores the significance of this change, the controversy surrounding it, and the future of Redis in the ever-evolving landscape of open-source software.
Redis and Its License Drama
Redis, a cornerstone tool for developers, has seen several changes in its licensing over the years. Initially, the database was available under the three-clause Berkeley Software Distribution (BSD) license, a popular open-source license. However, last year, Redis shifted to a more restrictive model, utilizing the Redis Source Available License (RSALv2) and Server Side Public License (SSPLv1). This change was intended to prevent major cloud providers from offering Redis as a managed service without contributing to the project.
Despite these efforts, the move led to backlash from developers, who criticized the decision for being too restrictive. As a result, a fork of Redis, called Valkey, emerged and gained popularity, with major companies like Amazon Web Services (AWS), Google, Ericsson, and Oracle adopting it. This split illustrated the tension between maintaining open-source integrity and pursuing monetization strategies.
Redis’ return to open-source licensing with AGPLv3 is a significant shift. The AGPLv3 license is approved by the Open Source Initiative (OSI) and comes with strict copyleft provisions, meaning that any modifications made to Redis and deployed over a network must be open-sourced as well. This “network clause” closes the so-called “SaaS loophole,” ensuring that cloud providers offering Redis as a service must either share their modifications or pay for a commercial license.
What Undercode Says:
The reversion of Redis to an open-source license is a strategic move, but not without complications. The change in licensing aims to ensure that Redis retains its foundational connection to the open-source community while simultaneously securing its business interests. Redis’ founder, Salvatore Sanfilippo, expressed a desire to give back to the community by releasing the new Vector Sets data type under the open-source AGPLv3 license, showing a strong personal commitment to the open-source ethos.
However, the license shift is not without its problems. While the AGPLv3 license allows Redis to prevent cloud providers from profiting off its software without contributing, it’s not universally accepted by the open-source community. Some critics, such as Peter Zaitsev and Vadim Tkachenko of Percona, argue that the AGPLv3 is one of the most restrictive open-source licenses. This makes it difficult for companies to adopt Redis without fear of legal ramifications when modifying or redistributing the software.
Moreover, the AGPL’s stringent terms often clash with company policies that prohibit the use of software with such restrictive clauses. This means that despite Redis’ return to open-source licensing, its practical adoption could be hindered by these very terms. For Redis, this creates a delicate balancing act between satisfying developers and securing its future in the cloud-driven economy.
Redis has also made it clear that it hopes the new license will address concerns about software-as-a-service (SaaS) providers, who have historically made money off Redis without contributing back to the open-source project. The AGPLv3, while effective in closing this gap, has the side effect of possibly alienating enterprise users who are hesitant to embrace a license that forces them to disclose changes made to the software when used over a network.
One of the most significant criticisms of Redis’ shift to AGPLv3 comes from Amanda Brock, CEO of OpenUK. Brock has pointed out that Redis, like many other companies that have jumped between open-source and proprietary models, has undermined the foundational principles of open source. Trust is key to the open-source community, and Redis’ history of switching licensing models may have damaged its relationship with developers and users alike. While Redis’ return to an open-source license is a welcome move for some, there is skepticism about how long it will last and whether Redis will continue to honor the open-source commitment in the long run.

- AGPLv3 Criticism: While AGPLv3 is an OSI-approved license, it remains controversial due to its restrictive terms, particularly the network clause that requires cloud providers to open-source their modifications.

Prediction
The shift back to AGPLv3 for Redis 8 is a pivotal moment in the open-source community, but its long-term success remains uncertain. While the new license may appease some developers, its restrictive nature could lead to continued fragmentation, as seen with the Valkey fork. Furthermore, major cloud providers like AWS and Google may continue to favor Valkey, a more permissive alternative, rather than adopting Redis under AGPLv3 terms. Redis’ challenge will be finding a sustainable balance between open-source ideals and monetization strategies, particularly in a cloud-dominated tech ecosystem.
As cloud services become increasingly central to software distribution, the future of Redis may depend on how well it can navigate the complex landscape of open-source licensing while also protecting its business interests. It will be interesting to see whether this licensing decision can restore developer trust or whether the company will face another backlash in the future.
