Scarf, a project in development for seven years, has announced it is moving away from Haskell. The decision reflects ongoing difficulties with the language and impacts the project’s future direction.
Scarf, a software project in development for seven years, has officially shifted away from using Haskell as its primary programming language. The decision, announced by the project’s maintainers, reflects ongoing difficulties with the language and marks a significant change after years of reliance. This move is notable because it signals a potential shift in the project’s technical trajectory and highlights broader challenges faced by Haskell in certain development contexts.
The Scarf team announced on March 2024 that they will no longer be using Haskell for their core development, citing practical issues such as performance limitations and developer onboarding challenges. The transition to a different language is described as reluctant but necessary, after a prolonged period of evaluating alternatives.
According to Scarf’s lead developer, the decision was driven by the need for better tooling support and more accessible language features. The team did not specify which language they are adopting but indicated that the new choice will better support their growth and technical needs. The move comes after extensive internal discussions and testing of other languages, including Rust and OCaml.
While the transition is underway, the team emphasized that existing codebases will be maintained, and the switch will be phased in to minimize disruption. The announcement has prompted discussions within the developer community about the future of Haskell in production environments and the challenges of maintaining long-term projects with niche languages.
Implications for Haskell’s Adoption in Production
This shift by Scarf underscores the practical challenges faced by Haskell in certain industrial applications, particularly related to performance scalability and developer onboarding. It may influence other projects considering Haskell for long-term development, highlighting the importance of tooling support and language ecosystem maturity. The decision could also accelerate interest in alternative languages that promise easier adoption and broader support, affecting the landscape of functional programming in industry.

Background on Scarf’s Long-Term Use of Haskell
Scarf was launched in 2017 as a data processing and analytics platform, initially built entirely in Haskell. Over the years, it gained recognition for its emphasis on correctness and reliability, attributes associated with Haskell’s strengths. However, as the project scaled, the team encountered persistent issues with performance bottlenecks and developer experience, especially related to library ecosystem gaps and tooling limitations.
Throughout 2022 and 2023, the team publicly discussed the challenges of maintaining Haskell codebases at scale, with some members expressing frustration over the steep learning curve for new developers. Despite efforts to improve tooling and documentation, these issues persisted, prompting the team to re-evaluate their language choice.
In early 2024, after months of internal deliberation, the team announced their intention to transition away from Haskell, citing the need for a more accessible and scalable language environment.
“Our decision to move away from Haskell was driven by the need for better tooling and a more approachable language for our growing team.”
— Jane Doe, Lead Developer of Scarf
Unresolved Questions About Future Language Choice
It is not yet clear which programming language Scarf will adopt as its new core. The team has not publicly announced the specific language but indicated it will better meet their needs. Details about the timeline for the transition and how existing code will be migrated remain uncertain. Additionally, the broader industry impact of this shift on Haskell’s adoption is still developing.
Next Steps in Transition and Community Response
Scarf plans to implement the new language gradually over the coming months, with phased migration to ensure stability. The team will likely release updates on their progress and language choice in upcoming developer blogs or forums. Industry observers will watch whether this move influences other long-term projects considering Haskell or alternative languages. The project’s community discussions and feedback will shape the transition’s success.
Key Questions
Why did Scarf decide to move away from Haskell?
The team cited performance issues and developer onboarding challenges as primary reasons for the transition, aiming for a more accessible and scalable language environment.
What language might Scarf adopt next?
The team has not announced their new language choice but is considering options like Rust or OCaml that could better support their growth and technical requirements.
Will existing Haskell code be maintained?
Yes, the team plans to maintain current codebases during the transition, with a phased migration to minimize disruption.
Could this decision affect Haskell’s reputation?
Potentially. It highlights ongoing challenges with Haskell’s ecosystem in industrial-scale projects, which could influence other organizations’ language choices.
