We research, build and deploy local-first technology for public institutions and regulated environments.
Jupiter Innovation Lab works between applied research and production software. We investigate new ways of building applications around a simple principle: computation and data should remain as close as possible to the organizations and people that own them.
We turn that research into experiments, prototypes, products and operational systems — developed in real environments, from software for Barcelona City Council to publicly funded R&D and new local-first architectures for public administration, regulated environments and potential dual-use applications.
Applications that carry their data and computational environment with them.
k3pler is a local-first application architecture for data-intensive, highly regulated environments. Data, business logic, analytics, GIS and selected AI capabilities execute directly on the user's device. Applications stay operational without permanent connectivity and synchronize securely when a network is available.
Software built for the complexity of a real city.
We develop operational software for Barcelona City Council, supporting the management and analysis of urban interventions and public-space operations. The work is a real environment in which to develop, deploy and validate the technologies behind Jupiter.
Don't generate the frames. Generate what creates them.
Toflr investigates a different approach to generative media. Instead of asking a model to produce every frame, it uses AI to create structured procedural representations that can be validated, modified and rendered locally — making animation reproducible, programmable and independent from continuous cloud rendering.
The project has received public support from the Generalitat de Catalunya for its development.
Our research focuses on architectures that reduce the dependency between computation and centralized infrastructure.
We explore systems where the primary working state lives with the user and the network becomes a synchronization mechanism rather than a permanent requirement.
Data, interface, logic, permissions and analytical capabilities can travel together as a portable computational object. We explore this model through k3pler and its portable application architecture.
Models are becoming small and efficient enough to execute on consumer and institutional hardware. We investigate AI that operates directly on local information, without that information leaving the device.
Local-first changes the role of the network. We experiment with peer-to-peer transport, encrypted replication and distributed synchronization for applications that must remain operational independently.
We explore authentication based on open standards, passkeys and infrastructure that organizations can operate and control themselves.
Toflr explores generative models as creators of executable procedural representations rather than final media.
The model generates the system. The device generates the result.
Moving data to a European cloud can address important jurisdictional and regulatory concerns. But the location of the server does not fundamentally change the architecture of the application.
Jupiter investigates another layer of technological sovereignty: giving organizations control over where their data lives, where computation happens, how intelligence is executed and when a network is required.
Choosing where a server sits solves part of the problem. Jurisdiction matters. It is a necessary step — but not the whole architecture.
Our goal is not to eliminate networks or cloud infrastructure. It is to make applications less dependent on them.
Some operational environments cannot assume permanent connectivity, unlimited bandwidth or continuous access to external cloud infrastructure. The properties that make local-first systems useful for public administration can therefore matter to critical infrastructure and defence.
Applications and data remain available when connectivity is degraded or unavailable.
Information can be distributed according to roles, permissions and operational requirements.
Queries, analytics, cartography and selected AI workloads run directly on sensitive data, without external cloud processing.
Distributed replicas synchronize when connectivity returns, while maintaining access control, integrity and encryption.
Potential applications include asset management, maintenance, logistics, technical documentation, offline cartography, field operations and local analysis of sensitive information. Deployment in defence environments would require additional integration, cryptographic hardening, classification policies, auditing, interoperability testing and the corresponding accreditation or certification.
Technological sovereignty requires more than choosing where a server is located. We favour open standards, portable data, European infrastructure where infrastructure is required, and local execution wherever it makes sense.
Our aim is to build systems that institutions can operate, understand and evolve — without unnecessary dependency on a single technology provider or hyperscaler.
We release selected tools, experiments and design resources developed inside Jupiter.
An open typeface derived from Geist and developed for the interfaces we build.
A halftone studio that runs entirely in the browser. Load an image, work the grid, export SVG or an animated snippet. No image ever leaves the device.
Components and tools extracted from our research and products — the reusable pieces of the local-first stack.
Technical notes from ongoing work on local-first software, distributed systems, local AI and procedural computing.
An independent applied technology lab based in Barcelona, working at the intersection of public technology, local-first software, distributed computing and artificial intelligence. Our work ranges from experimental systems to software deployed in public institutions.
We collaborate with administrations, research institutions and technology partners to turn architectural research into operational systems. We are interested in a small set of persistent questions.
Our products are attempts to answer those questions.
