The programmable cloud for AI-native applications. Eliminate vendor fragmentation and replace fragmented SaaS bills with a single sovereign cloud combining compute, microVMs, databases, maps, auth, storage, mail, and MCP.
Compare PGB Hub's unified programmable cloud against stitching together multiple separate SaaS vendors or building custom infrastructure from scratch.
| Cloud Capability | PGB Hub Sovereign Cloud | Fragmented SaaS Stack | DIY VPS / Raw Stack |
|---|---|---|---|
| Serverless Compute & Webhooks | Sub-10ms Node/Python execution, HMAC webhooks & cron | External Serverless Providers ($$$ base + cold starts) | Manual PM2/systemd daemons, no auto-scaling |
| MicroVM Containers & CRIU Scale-to-Zero | CRIU memory snapshot to 0 RAM when idle (<20ms resume) | Separate container hosts, 24/7 idle RAM charges | Always-on Docker containers consuming 100% RAM |
| Dedicated PostgreSQL 17 + JSONB + PostGIS | Full PostgreSQL 17, schema-free JSONB, PostGIS 3.4 & pgvector | Third-Party Database SaaS ($$$ compute scale-up & bandwidth) | Raw Postgres with manual SSL, pooling & extension installs |
| Self-Hosted Maps & Geolocation Gateway | Standard vector tiles & routing at a fraction of traditional map costs | Proprietary Map SaaS ($$$ per 10k tile loads & search sessions) | Complex self-hosted TileServer GL & OSRM compilation |
| Built-In Auth, OTP & Automated RLS | Passwordless 6-digit OTP, magic links, JWT & auto-injected RLS | Third-party identity providers ($$$ per MAU exponential fees) | Custom auth microservice, token stores & session maintenance |
| Partitioned S3 Object Storage & CDN | Isolated S3 namespaces, 15-min presigned URLs & CDN streaming | Separate Object Storage & CDN (multi-step IAM configuration) | Local disk volume storage without multi-region durability |
| Agent-Native Model Context Protocol (MCP) | 1-click MCP introspection & action execution for AI coding agents | Custom manual glue code and API prompt injection risks | No native MCP server or schema introspection bridge |
| Consolidated Ingress & Single Invoice | One sovereign domain (*.pgbhub.app) & unified predictable bill | Multiple separate invoices, conflicting billing meters & DNS hops | Single VPS server bill, but high ongoing DevOps burden |
How PGB Hub compares against fragmented third-party clouds and DIY infrastructure in production environments.
Why string together a dozen disparate vendors when you can run on a single sovereign cloud?
Modern web and mobile stacks are choked with fragmentation: external serverless platforms for compute, separate hosted databases, expensive map API vendors for tiles, third-party identity providers for authentication, separate object storage providers for uploads, and third-party email services for transactional mail. Every piece introduces separate credentials, conflicting billing meters, network hops, and operational friction. PGB Hub unifies all 8 sovereign subsystems under a single URL (https://<project>.pgbhub.app) and one unified SDK client.
Instant sub-10ms handlers plus full Docker containers that freeze to 0 RAM when idle.
Traditional serverless functions suffer from unpredictable cold starts and vendor-locked runtimes, while traditional container hosts charge constantly for idle memory. PGB Hub combines sub-10ms pre-warmed Node.js & Python function workers with CRIU memory snapshots for microVM containers. When traffic stops, containers snapshot to zero RAM and resume in under 20 milliseconds upon the next incoming HTTP request.
Get schema-free JSON collections, PostGIS spatial queries, and pgvector embeddings in one engine.
Starting with isolated NoSQL document stores frequently results in painful database migrations once relationships emerge. At the same time, vanilla database setups require complex DevOps, connection poolers, and external vector extensions. PGB Hub gives every project a dedicated PostgreSQL 17 instance with automated GIN path indexing on JSONB, PostGIS 3.4 spatial intelligence, and pgvector semantic search.
High-performance vector tiles, search autocomplete, and turn-by-turn routing at ultra-low rates.
Geospatial features are notorious for ballooning cloud bills: traditional map providers charge steep rates per 10k tile requests, search sessions, and directions queries. PGB Hub includes a self-hosted PGB Maps & Navigation Gateway that delivers street and dark vector map tiles, search autocomplete, and routing at a fraction of the cost of external map platforms. Mobile and web apps can switch tile and routing endpoints seamlessly with zero code restructuring.
Eliminate third-party auth per-MAU taxes, storage glue code, and transactional email friction.
Third-party identity providers levy punitive pricing as Monthly Active Users grow, while setting up separate storage presigned uploads and transactional email requires days of cloud configuration. PGB Hub bakes authentication (OTP, magic links, JWTs, automatic RLS scoping), S3-compatible partitioned object storage with 15-minute presigned URLs, and high-deliverability transactional mail right into your sovereign platform.
Give Cursor, Claude Desktop, and autonomous coding agents live context to your entire cloud.
AI-assisted development is transforming software engineering, but LLMs struggle without real-time database schema insight and live execution APIs. PGB Hub provides an official Model Context Protocol (MCP) server that connects Cursor IDE, Claude Desktop, Windsurf, and custom AI agents directly to your live schemas, tables, serverless functions, and storage with safe execution boundaries.
Provision databases, serverless compute, microVM containers, maps, auth, storage, and agent MCP tooling under one unified sovereign endpoint.
