Headless / Modular / Multi-tenant engine
Prometheus EdTech
The headless, modular back-end nucleus that powers scalable education products. Brands license the core and build their own UI/UX around it - live classrooms, adaptive scoring, AI vocabulary, real-time chat and a unified payments module behind one tenant-aware control plane.
A proprietary intellectual-property asset of Edusoft Solution Ltd.
4 composable services 3 turnkey personas 1 unified identity fabric many tenants per cluster
01. Why Prometheus is different
Most "learning management systems" are monoliths you rent. Prometheus is a headless, domain-decomposed engine you license and own the experience on top of. Its technical nature is a proprietary framework of relational database structures, secure API routing management, multi-language hot-reloading components and custom data-processing algorithms.
Every revenue-critical concern - payments, real-time chat, the dictionary, the lesson runtime - is a separately deployable service a tenant can switch on, switch off, or bring their own implementation of.
Bring your own UI
A fleet of independent micro-frontends. Tenants theme tokens, swap layouts or replace whole surfaces without touching the backend contract.
Own your payments
A unified payments module abstracts packages, pricing, promos and acquiring. Real-time execution, no lock-in to a single fixed aggregator.
Toggle the chat
Real-time messaging is a standalone microservice. Flip it per tenant; when off, the platform degrades gracefully with no dead code paths.
Curate the dictionary
An AI-powered vocabulary service with per-tenant language packs, enable/disable and editable word sets - students train on your corpus.
Author your content
Lessons and homework are data, not code. Tenants populate the platform with their own curriculum through the authoring layer.
Real-time by default
A real-time event fabric keeps the live classroom, homework state and chat in lock-step across teacher and student.

02. The architecture, at a glance
A modular core orbited by three single-responsibility services, stitched together by an API gateway and a real-time event bus. The browser never talks to a service directly - a thin backend-for-frontend normalizes everything and enforces the tenant boundary.

A signed access token minted by the engine is the single identity fabric - every satellite service validates it against the same trusted key, so authorization is stateless and tenant-aware.
The trick that makes it licensable: the access token carries
userId, role and tenantId. Every service is multi-tenant from the data layer up - no shared mutable state leaks between customers, so one cluster can host many brands safely.03. Three personas, shipped on day one
The happy path is opinionated and complete out of the box. A new tenant gets these three accounts working before writing a line of code.
Student
Joins live lessons, completes homework, drills vocabulary, chats with the teacher, pays for packages.
Teacher
Runs the video classroom, assigns and grades homework, tracks progress, messages students in real time.
B2B Admin
Configures the tenant: branding, enabled modules, pricing, dictionary languages and content libraries.
04. Anatomy of a lesson
What happens when a student walks into a live class - the orchestration the platform handles for you.
1Student to Classroom UI: opens the lesson.
2UI to API Gateway to Engine: resolves the lesson plan, materials and prior progress (with a signed access token).
3UI to Realtime Bus: subscribes to the lesson; teacher presence and live slide sync stream in.
4Student to Dictionary: saves an unknown word straight into a training set.
5Teacher assigns homework to Engine to Student: it appears instantly over the realtime bus. No polling, no stale tabs.
05. The Unified Payments Module
A purpose-built billing engine optimized for real-time transactional event execution - without binding the platform to any single fixed third-party aggregator. The core never touches a card; it speaks to the module through a bridge that owns the pricing catalog, promotions and gateway routing.
1Student to Engine: chooses a package.
2Engine to Payments Module: resolves price + promo for the tenant.
3Module to acquiring rail: creates the transaction; the student is taken to the hosted payment page.
4Webhook to Module: payment confirmed.
5Module to Engine (async event):
subscription.activated - access granted instantly.Pricing, promo codes and acquiring credentials live entirely inside the module. The acquiring rail is interchangeable - the platform is never locked to one aggregator.
06. Five control planes for every tenant
Everything a buyer asked "can we customize this?" about is a first-class, documented configuration surface.
1White-label UI
Independent micro-frontends consume a theme-token contract. Tenants override colors, typography and logos, or replace entire surfaces - the backend contract is untouched.
2Payment control
The payment admin manages packages, pricing tiers, promotions and acquiring credentials per tenant. Enable the rails you're licensed for; the rest stay dark.
3Chat availability
Chat is a deployable microservice gated by a feature flag. Turn it off and the UI hides the surface; turn it on and presence + history light up.
4Dictionary scope & languages
The AI dictionary exposes per-tenant language packs and editable word sets. Choose which languages ship, which word sets are visible, and whether AI generation is on.
5Content authoring
Lessons and homework are structured data. Tenants populate their own curriculum through the authoring layer - the platform ships empty and you fill it with your pedagogy.
07. On the roadmap: a shared workspace
Two upcoming capabilities turn the classroom into a collaborative file space - the most requested gap in remote tutoring.
New
In-lesson file exchange
Teacher and student drag-and-drop files into the live classroom. Object storage with signed URLs, virus scanning and per-lesson retention. The realtime bus broadcasts a file.shared event so the attachment appears instantly for both sides.
New
Homework uploads & review
Students submit essays, audio or PDFs against an assignment. Files are versioned, the teacher annotates inline, and the dictionary service can auto-extract vocabulary to seed the next training set.
08. Architecture by responsibility
Each layer is defined by what it does, not by the brand behind it. The platform is built from proven, interchangeable building blocks - every one can evolve independently without disturbing the others.
09. Proven in production: the Englishdom migration
Prometheus is not a slide-deck concept. Its first full-scale implementation is the live Englishdom platform and its All Right Pro sub-segment - chosen precisely because they were hard.
The starting point: Englishdom ran on a legacy monolithic codebase first written more than 15 years ago, largely unchanged since - riddled with performance bottlenecks and scaling limits eroding the brand and depressing sales. Edusoft Solution Ltd acquired the platform software itself, without the underlying customer base, and began a phased replacement of the legacy core with the Prometheus engine while preserving the established UX/UI.
What was re-engineered
Scheduling System
The lesson-booking and calendar core rebuilt as an autonomous service integrated into the engine.
Adaptive Learning Scoring
Custom data-processing algorithms that score progress and adapt the learning path per student.
Unified Payments Module
Real-time transactional event execution, decoupled from any fixed third-party aggregator.
Phased rollout - from March 6, 2026: the engine is introduced module-by-module, replacing the platform's technical core. The interface and basic functionality can stay unchanged at the start, so end users keep a stable experience while the foundation is modernized underneath them. This deployment is the active validation environment that proves the B2B licensing model of the asset.

10. The commercial model
Prometheus is a proprietary, cross-functional and reusable technology asset. Edusoft Solution Ltd monetizes it two ways at once - and each reinforces the other.
License the core
External brands license the headless infrastructure and build their own user-facing UI/UX layers on top - a true white-label engine.
Run it ourselves
The same engine powers Edusoft's own EdTech operations serving consumers directly - dogfooding at scale.
Compounding R&D
Real-world usage continuously hardens the core and funds further development - every tenant makes the platform better.
Prometheus EdTech - stealing fire from the monolith and handing it to every brand.
