Frequently asked questions

FossibleWorks is an implementation partner for enterprise ERPNext, hospital information systems, self-hosted Medplum and FHIR, DevOps for open-source stacks, AI-agent product delivery, and Applied AI. We help digital health builders and enterprises build, deploy, and scale with 100% tech ownership and no vendor lock-in.

Yes. Our core products — Fossible HIS (GPL-3.0) and Medplum (Apache 2.0) — are fully open source. You get complete source code access, can self-host anywhere, and there are no per-user licensing fees. We believe open source is the right foundation for critical healthcare infrastructure.

We offer multiple engagement models: Fossible Sprints provide dedicated dev pods on a flat monthly fee with AI-augmented development. For enterprise deployments, we scope fixed-fee implementations. We also offer managed hosting through Espresso Cloud. Every engagement comes with our promise of 100% tech ownership — your data, your software, total freedom.

FossibleWorks operates through two entities: Fossible Works Inc, headquartered in Albany, New York (USA), and Tacten Services LLP, based in Bangalore, India. We serve clients across the Americas, EU and UK, India, APAC, and EMEA — with the contracting entity determined by your jurisdiction.

Medplum is an open-source FHIR R4 server and health data platform licensed under Apache 2.0. It provides a standardized clinical data repository with a TypeScript-native SDK, React component library, PostgreSQL-backed FHIR storage, and built-in HIPAA and SOC 2 compliance. FossibleWorks provides implementation, customization, and managed hosting services for Medplum.

Yes. Medplum can be fully self-hosted on your own infrastructure — AWS, GCP, Azure, or on-premise. FossibleWorks provides end-to-end deployment, configuration, and managed hosting services for self-hosted Medplum installations, ensuring compliance and production readiness.

FHIR (Fast Healthcare Interoperability Resources) is an HL7 standard for exchanging healthcare data electronically. It matters because it provides a standardized, portable format for clinical data — enabling interoperability between systems, regulatory compliance (ONC, CMS), AI-ready analytics, and patient-facing applications that work across providers.

We provide Medplum implementation and customization, SMART on FHIR app development, clinical data migration (HL7v2, CSV, legacy systems), healthcare compliance configuration (HIPAA, ABDM, NABH), interoperability services (HL7v2, FHIR, CDA, DICOM), and full health data stack integration with analytics and AI layers.

All three store and serve FHIR R4 data. HAPI FHIR is an open-source Java server library you build an application around, and Aidbox is a commercial FHIR platform. Medplum is Apache 2.0 and TypeScript-native, and ships with authentication, access policies, Bots automation and React components — so teams build apps on it rather than around it. We recommend it when you want an open-source, self-hostable FHIR backend with an app framework included.

Yes. We build pipelines from legacy systems, CSV exports and HL7v2 feeds into conformant FHIR R4 resources — validated, complete and with provenance tracking — and connect EHR, LIS/RIS, pharmacy, imaging and HIE systems using HL7 v2, FHIR R4, CCDA, DICOM and ADT.

Yes. We build SMART on FHIR apps and patient or clinician portals on Medplum and other FHIR R4 servers, with OAuth-based launch, FHIR-native data models and the interoperability work needed to plug them into existing EHRs.

Yes. We cover the full stack for digital health builders: FHIR and Medplum for clinical data, an open-source HIS on ERPNext for hospital operations, Espresso Cloud for self-hosted DevOps, and AI agents on top — so you build, deploy and scale with one team.

Yes. We scope and deliver Applied AI work — agent harnesses, context engineering, retrieval (RAG), fine-tuned open-weight models and work sold as a service — with permissions, version history and audit trails on infrastructure you control.

Most clients start with a 2-week, fixed-fee AI Readiness Audit: a substrate assessment, agent-readiness score, ranked use-case shortlist and a token-cost model. From there, an Agent Build Pod ships one production workflow in 6–12 weeks, a Model Lab fine-tunes and self-hosts a model in 4–8 weeks, or we run agents ongoing under a Work-as-a-Service model.

Yes. Healthcare is our deepest domain: we connect AI agents to FHIR data in Medplum and to hospital operations in ERPNext through permissioned MCP servers, so agents read and write through the same access controls and audit trails as your staff.

Fossible HIS is an open-source Hospital Information Management System built on Frappe/ERPNext. It unifies EHR, practice management, LIS (Lab Information System), RIS (Radiology Information System), billing, inventory, HR, and pharmacy on a single platform — with a single database, a single API, and zero per-user licensing fees.

Fossible HIS is fully open source under the GPL-3.0 license. There are zero per-user licensing fees — no seat-based pricing, no tiered feature gates. You pay only for implementation, customization, and optional managed hosting services. The source code is available on GitHub.

Fossible HIS supports FHIR R4, HL7, DICOM, LOINC, ICD-10, and SNOMED-CT. It is HIPAA-compliant ready and supports ABDM (Ayushman Bharat Digital Mission) and NABH compliance requirements for the Indian healthcare market.

Fossible HIS is built for multi-site hospital groups, diagnostic lab chains, specialty clinics, health-tech startups, and government health programs that need an open-source, standards-compliant, self-hostable healthcare platform without per-user licensing overhead.

Espresso Cloud is our private CI/CD and managed cloud infrastructure platform. It provides Frappe/ERPNext-specialized deployment pipelines, Node.js framework support, 99.9% SLA with disaster recovery, and full DevOps management — so your team can focus on building features instead of managing infrastructure.

Hydra AI is our purpose-built AI development agent for ERPNext and Frappe applications. It features MCP tool calling, deep ERP domain knowledge, token-optimized context management, and code quality guardrails — accelerating Frappe/ERPNext development while maintaining enterprise-grade code standards.

Fossible Sprints is our AI-augmented product development service. You get a dedicated dev pod (engineers + AI agents) on a flat monthly fee. We use a tiered AI strategy (Claude Opus, Sonnet, Haiku) with enterprise guardrails — delivering faster iteration cycles while maintaining code quality and security standards.

Yes. Both Fossible HIS and Medplum are built with HIPAA compliance in mind — including access controls, audit logging, encryption at rest and in transit, and fine-grained role-based access control (RBAC). Medplum additionally provides SOC 2 compliance and ONC certification readiness out of the box.

Absolutely. Our engagement promise is 100% tech ownership. All source code, data, configurations, and infrastructure are yours. There is no vendor lock-in, no proprietary dependencies, and no data hostage situations. You can fork, modify, and deploy independently at any time.

Yes. Our entire stack — Fossible HIS, Medplum, Espresso Cloud pipelines, and supporting services — can be self-hosted on your own infrastructure (AWS, GCP, Azure, or bare metal on-premise). We provide full deployment support, documentation, and optional managed hosting if you prefer us to handle operations.
