REPLIT PLATFORM

Navigator Nexus

Version 4.0.3 Status PRODUCTION Cutoff January 2026 Org Higgs AI LLC

0 Purpose

The Replit Platform Navigator is an evidence-backed knowledge graph that maps Replit's capabilities, constraints, and decision paths. It enables AI assistants to give accurate platform guidance by separating verified claims from gaps and providing operational runbooks for common scenarios.

Identity Rule: This map is a knowledge source, not a persona. AI systems should use their native assistant identity and cite the map as reference data, not roleplay as a "Clerk."

1 Map Statistics

The Navigator Nexus contains comprehensive coverage of the Replit platform with explicit evidence backing.

2 Status Taxonomy

Every claim in the map is tagged with a standardized status that indicates its verification level.

Status Meaning
VERIFIED Claim confirmed in official documentation with at least one evidence ID
VERIFIED_LIMITED Claim verified but with caveats (beta, enterprise-only, coming soon)
NOT_DOCUMENTED Actively searched for and not found in documentation
DEPRECATED Feature existed but has been removed or replaced
THIRD_PARTY Capability exists via external integration, not native

Forbidden Statuses: UNVERIFIED, INFERRED, PROBABLY, MAYBE. If we can't verify it, we don't claim it.

3 Table of Contents

The map is organized into navigable sections for quick lookup.

Core Platform

Nix environment, Git integration, .replit config, deployment types (Static, Autoscale, Reserved VM, Scheduled)

Development Experience

Agent 3 with 200min autonomy, Connectors, debugging tools, logs, metrics, rollbacks

Security & Enterprise

SOC2 Type II certified, HIPAA not supported, VPC coming soon, SAML SSO for enterprise

Data & Storage

PostgreSQL (10GB cap), Object Storage, protocol constraints (HTTP/WebSocket only, no UDP)

Portability & Exit

Git export, pg_dump, no vendor lock-in. Full code ownership.

Decision Compositions

Pre-built decision trees for SaaS MVP, Enterprise Eval, When to Migrate, Anti-patterns

4 Evidence Volatility

Documentation URLs drift as Replit restructures. The map tracks evidence volatility and provides fallback URLs.

Volatility Class Description
IMMUTABLE Historical content that won't change (blog posts, changelogs)
STABLE Core documentation unlikely to move frequently
DYNAMIC Feature pages that may be restructured
VOLATILE Pricing, limits, rapidly evolving features - ALWAYS verify at source

Staleness Warning: Replit ships rapidly. Always verify current state for pricing, limits, and new features.

5 Known Gaps Registry

The map explicitly documents platform limitations with 14 registered gaps. Honesty about what's missing is core to the assurance model.

6 Negative Evidence Registry

The map tracks 14 documented capability searches that returned no results. This prevents false claims about features that don't exist.

Scan ID What Was Searched
NEGSCAN:HIPAA HIPAA compliance, BAA, healthcare certification
NEGSCAN:UDP UDP ports, inbound UDP, game server protocols
NEGSCAN:GPU GPU instances, CUDA, ML accelerators
NEGSCAN:NATIVE_MOBILE iOS SDK, Android native, Bluetooth API
NEGSCAN:UPTIME_SLA Published SLA, uptime guarantee percentage

7 Operational Runbooks

The map includes step-by-step guides for common operational scenarios.

RUNBOOK:DEPLOY_CRASH

Deployment crashing or restarting. 502/503 errors. Container restart loops.

RUNBOOK:AGENT_BROKE_APP

App stopped working after Agent changes. How to rollback and recover.

RUNBOOK:SLOW_APP

High latency, timeouts, cold start issues. Performance debugging.

RUNBOOK:DEBUG_PRODUCTION

Safely investigate production issues without SSH access.

RUNBOOK:COST_ESTIMATION

Estimate monthly costs for enterprise planning without a calculator.

8 Decision Compositions

Pre-built decision trees answer common architectural questions.

Composition Type Purpose
COMP:SAAS_MVP USE_CASE Decision tree for SaaS projects on Replit
COMP:ENTERPRISE_EVAL EVALUATION Checklist for enterprise evaluators
COMP:WHEN_TO_EJECT DECISION Migration triggers and playbook
COMP:ANTI_HEALTHCARE ANTI_PATTERN DO NOT USE for HIPAA/PHI workloads
COMP:ANTI_GAME_SERVER_UDP ANTI_PATTERN UDP game servers need hybrid architecture
COMP:MIGRATION_VERCEL MIGRATION Feature mapping from Vercel
COMP:MIGRATION_DOCKER MIGRATION Nix translation guide from Docker

9 Citation Protocol

When citing claims from this map, use the standardized ID format.

Citation Validation: Before citing any ID, verify it exists in this map. Do not fabricate IDs like GAP:X if only NEGSCAN:X exists.

10 Example Interaction

Here's how the Navigator handles a typical platform question:

Q: Can I run a real-time multiplayer game server on Replit?
Short Answer: Partially. WebSocket-based games work well. UDP-based games (most FPS/action games) require a hybrid architecture.

Evidence: [CLM:PROTOCOL:WEBSOCKET_SUPPORTED] confirms WebSocket support. [GAP:UDP] documents the UDP limitation. [COMP:ANTI_GAME_SERVER_UDP] provides the anti-pattern guidance.

Recommendation: For turn-based or WebSocket games, Replit works. For UDP-dependent games, use Replit for lobby/matchmaking and external game servers for real-time action.
