TL;DR
Threlmark has unveiled a new approach to roadmaps, making the entire plan a JSON file stored locally. This method emphasizes simplicity, interoperability, and ownership, challenging traditional SaaS tools.
Threlmark has introduced a novel approach to project roadmaps, where the entire plan is stored as a plain JSON file on the user’s disk, eliminating reliance on SaaS APIs and vendor lock-in. This approach is discussed in detail in Disk Is the Contract: Inside Threlmark’s Local-First Architecture. This change emphasizes local ownership, interoperability, and durability, marking a significant shift from traditional cloud-based tools.
The core of Threlmark’s approach is that the roadmap exists as a simple JSON file, which any program capable of reading or writing JSON can access. This design ensures that the plan is not confined within a vendor’s API or SaaS platform, reducing dependency and increasing control for users. The roadmap is also scored, with each item assigned a priority, enabling clear prioritization and trade-offs. Because the file is stored locally, it is inherently durable and portable, outliving the tools that create or modify it. The system supports automated agents that can read and update the file directly, creating a live, shared workspace for human and AI collaboration. Threlmark’s solution is open source under the MIT license, with detailed internals available for review at threlmark.com.While this approach offers benefits in simplicity and interoperability, it is not designed for large-scale, multi-user environments requiring real-time collaboration or conflict resolution. The reliance on a single file means that concurrent edits by multiple users across different locations could lead to conflicts. Additionally, the scoring system depends on accurate prioritization, which is subject to human or agent judgment. The risk of agent mis-writes also necessitates guardrails and review processes.
Threlmark — disk is the contract
The roadmap is a plain JSON file on your disk. The board is just a view over it — and your tools and your agents read and write the same file directly.

Implications for Project Management and Data Control
This new approach challenges the dominance of SaaS-based roadmap tools by emphasizing local ownership and interoperability. It also relates to the broader conversation about content discovery and AI search, as seen in The referral. How AI search severs the content-for-traffic contract that funded the open web. It offers users a durable, vendor-agnostic artifact that can be integrated with any JSON-compatible tool or agent, reducing lock-in and increasing control over project plans. For small teams or operators, this could streamline workflows and improve data portability. However, it also sacrifices some features of real-time collaboration and conflict management found in traditional tools, making it more suitable for smaller-scale or automated environments.

Shift Toward Local-First, Open Data Roadmaps
Traditional project management tools rely heavily on SaaS platforms, which often lock users into specific vendors and APIs. Threlmark’s philosophy advocates for a shift toward local-first, open formats, with the roadmap as a plain JSON file. This concept aligns with broader trends in open data and decentralization, emphasizing control, durability, and interoperability. The idea is rooted in the understanding that operational data, like roadmaps, should outlive the tools that generate them, ensuring long-term access and flexibility.
“A roadmap is only useful if the thing that updates it and the thing that reads it agree on where it lives. Threlmark’s approach makes the roadmap a simple, shared file on disk, removing vendor lock-in.”

Limitations and Risks of a Disk-Based Roadmap System
While the approach offers durability and interoperability, it is not suited for large, collaborative teams requiring real-time editing or conflict resolution. The reliance on a single JSON file raises concerns about concurrent edits and potential data corruption if agents mis-write. For more on licensing and legal considerations, see Raw-feed licensing. The contract that doesn’t exist yet. Guardrails and review processes are necessary to mitigate these risks. It remains unclear how well this system scales beyond small teams or automated environments, and how it handles complex permissioning or audit trails.

Next Steps for Adoption and Development
Threlmark plans to release the open-source software and detailed documentation at threlmark.com, encouraging community review and contribution. Future updates may include tools for conflict resolution, versioning, and enhanced collaboration features, although the core philosophy emphasizes simplicity and control. Users and small teams are expected to experiment with the system, providing feedback on its practical benefits and limitations in real-world scenarios.

Key Questions
How does this approach compare to traditional SaaS roadmap tools?
Unlike SaaS tools, Threlmark’s method stores the entire roadmap as a local JSON file, giving users full control and avoiding vendor lock-in. It supports interoperability with any JSON-compatible program but lacks real-time collaboration features of cloud-based tools.
Is this system suitable for large teams or enterprise environments?
No, this approach is designed primarily for small teams or operators. It does not support multi-user real-time editing or conflict resolution at scale, which are typical requirements in large organizations.
What are the main risks associated with using a disk-based roadmap?
The main risks include potential data conflicts from concurrent edits, agent mis-writes, and lack of built-in conflict management. Proper guardrails and review processes are necessary to mitigate these issues.
Can I integrate this system with existing project management tools?
Yes, since the roadmap is a plain JSON file, it can be integrated with any tool capable of reading or writing JSON, allowing flexible workflows and custom automation.
