What it is

REGnosys offers Rosetta, a collaborative low-code platform for regulatory reporting. Rosetta manages data pipeline development from design through deployment and monitoring. Its DSL generates executable code from models and can package that code as an API. A universal integration API and mapping tools connect existing systems, databases, and messaging formats, while Rosetta Monitor audits and traces data flow through pipelines.

REGnosys lists financial institutions, regulators, trade associations, and market infrastructure providers among its customer groups. The Rosetta DSL is open source and was released in 2019 with the ISDA Common Domain Model. Rosetta can be deployed on-cloud or on-premises and is platform agnostic. Its free Community plan has no time limit and requires no credit card, but it is for non-commercial public projects only, with three workspaces and 500 API requests per user each month. Essentials costs £417 a month, billed annually (£500 billed monthly); Pro and Enterprise include private projects.

The review

REGnosys’s Rosetta platform is for building and operating regulatory reporting data pipelines. It best suits financial institutions and other organizations that need to model, integrate and trace regulatory data flows. Its connected workflow is a strong fit for those teams, though private commercial projects start at the Pro plan.

Overview

Rosetta covers pipeline development from design through deployment and monitoring. Its modelling language generates executable code that can be packaged as an API, while integration tools map existing systems, databases and messaging formats. Rosetta Monitor traces physical data flows through pipelines, bringing auditability into the same workflow as development and operation.

The Rosetta DSL is open source and was released with the ISDA Common Domain Model in 2019. Rosetta can run on-cloud or on-premises and is platform agnostic, giving teams deployment flexibility. REGnosys says it encrypts data in transit and at rest using TLS, and offers client key management and peered VPN setup. Dedicated servers and hardware can separate data, while live-live systems support continuity. The paid plans’ shared or private hardware distinction matters to organizations choosing a deployment tier.

Key features

  • Pipeline modelling: Rosetta manages pipeline development from design through deployment and monitoring. That end-to-end scope can help teams keep model work connected to operations; teams needing only a narrow reporting tool may not need the full platform.
  • Executable models and APIs: The Rosetta DSL generates executable code from models and can package it as an API. This gives development teams a route from model to implementation within Rosetta.
  • Integration tools: A universal integration API and mapping tools cover existing systems, databases and messaging formats. That breadth is useful where regulatory data must move between established systems.
  • Auditability: Rosetta Monitor traces physical data flow through pipelines. This makes it relevant for organizations that need to follow how data moves, alongside the platform’s validation rules and audit trail.

Pricing

Rosetta has a no-time-limit free plan with no credit card required, but Community is for non-commercial use and public projects only. Its three workspaces and 500 API requests per user each month make it suitable for public work, not private commercial deployment.

PlanPrice and termsWhat it includes
CommunityfreeNon-commercial use, public projects only, 3 workspaces per user and 500 API requests per user/month.
Essentials£417 a month, billed annually (£500 billed monthly)Regular commercial contributor; public projects only; 5 workspaces per user; 1,000 API requests per user/month; shared hardware.
Pro£1,334 a month, billed annually (£1,600 billed monthly)Private commercial use; public and private projects; 10 workspaces per user; 1 guest user per user; 1,000 API requests per user/month, then £0.01 per API request; private hardware.
Enterprise£2,000 a month, billed annually (£2,400 billed monthly)Commercial use; public and private projects; 50 workspaces per user; 5 guest users per user; project administration; 10,000 API requests per user/month, then £0.01 per API request; private hardware.

Essentials is the entry point for commercial contributors, but it retains the public-project restriction and shared hardware. Pro is the first tier for private commercial projects and adds a guest user per user and private hardware. Enterprise raises the workspace and API allowances, increases guest access and adds project administration; its higher request allowance may suit larger workloads. Pro and Enterprise charge £0.01 per API request above their monthly per-user quotas. No free trial is offered.

Platforms

Rosetta is available as an API, self-hosted deployment and web platform. Its on-cloud and on-premises options give organizations a choice of hosting approach, while platform-agnostic deployment avoids tying the product to one platform.

Who it's for

REGnosys identifies financial institutions, regulators, trade associations and market infrastructure providers as customer groups. The strongest fit is an organization building regulatory data pipelines that can use model-driven code generation, system mapping and data-flow tracing together. Community can serve non-commercial public projects; commercial teams working on public projects can consider Essentials, while private commercial work requires Pro or Enterprise.

Pros and cons

Pros

  • One platform spans pipeline design, deployment, monitoring, code generation and integration, which suits teams coordinating those stages.
  • Rosetta Monitor traces physical data flow, and validation rules and an audit trail support oversight of reporting workflows.
  • Cloud and on-premises deployment, plus data separation and key-management options, give organizations choices for operating the platform.
  • The free Community plan has no time limit and requires no credit card, making it accessible for non-commercial public projects.

Cons

  • Community excludes commercial use and private projects, so it cannot serve as a free route to private production work.
  • Essentials still limits projects to public ones and uses shared hardware; private commercial projects begin at £1,334 a month billed annually.
  • Pro includes only 1,000 API requests per user/month before £0.01 per additional request, so higher-volume use can add charges.
  • Essentials and higher tiers have substantial monthly prices, and the free plan’s 500-request allowance is limited to public, non-commercial use.

Alternatives

Elite Reporting Platform is a paid alternative with Android, iOS, Linux, macOS, Windows, web, API, extension and self-hosted platforms. Arelle is a free, open-source XBRL platform with desktop builds, a Python package, Docker image and community plugins; choose it if that XBRL toolset fits your needs. FIS Data Integrity Manager is a paid web alternative. REGREP offers freemium access, including a TIN Validator at €0.01, paid once in 100-record blocks for bulk and API use across 111 countries, and FATCA at €500 a year for one entity with one correction. Aguilonius XBRL Factory-SE is a paid alternative. Amelkis XBRL is a paid web alternative with custom quote pricing and a free demo. CoreFiling Seahorse is a paid web alternative. Reg360 is a paid web alternative with pricing available upon request.

Verdict

Choose REGnosys if your organization needs a model-driven regulatory reporting platform that connects pipeline development, integration and data-flow auditing, and if its project and API limits fit your workload. Its no-cost plan is useful for non-commercial public projects, but private commercial work requires a paid Pro or Enterprise subscription, making it a poor fit for teams seeking a low-cost private deployment.
