MaxKB implements a document ingestion pipeline that parses uploaded files (PDF, Word, Markdown, etc.), chunks content into paragraphs, generates vector embeddings using PGVector-backed PostgreSQL, and indexes them for semantic retrieval. The system uses Celery for asynchronous batch embedding tasks, enabling non-blocking document processing at scale. Paragraph-level granularity allows fine-grained retrieval and citation tracking.
Unique: Uses Celery-based asynchronous batch embedding with paragraph-level granularity and PGVector native integration, enabling non-blocking document ingestion at enterprise scale while maintaining citation-level traceability through paragraph metadata tracking.
vs alternatives: Faster than cloud-only RAG solutions (Pinecone, Weaviate) for on-premise deployments because embeddings are generated locally and stored in PostgreSQL without external API calls; more granular than LangChain's default chunking because paragraph boundaries are tracked separately.
MaxKB abstracts multiple LLM providers (OpenAI, Anthropic, Ollama, DeepSeek, Qwen, Llama3) through a unified interface that handles provider-specific API contracts, token counting, and streaming response aggregation. The chat system implements server-sent events (SSE) for real-time token streaming to clients, with built-in fallback handling if a provider fails. Model configuration is stored per-workspace, enabling multi-tenant model isolation.
Unique: Implements provider abstraction at the chat layer with SSE-based streaming and per-workspace model configuration, enabling seamless provider switching without chat logic changes; includes native support for local models (Ollama) alongside cloud providers in the same interface.
vs alternatives: More flexible than LangChain's LLMChain because it abstracts provider switching at the chat level rather than chain level, and supports local models natively without requiring separate infrastructure; simpler than building custom provider adapters because MaxKB handles streaming, token counting, and fallback logic.
MaxKB implements a batch processing system for document embedding using Celery task queues. When documents are uploaded to a knowledge base, embedding tasks are queued asynchronously. The system tracks the status of each batch (pending, processing, completed, failed) and provides progress updates via WebSocket or polling. Failed embeddings can be retried with exponential backoff. Batch operations are idempotent; re-processing the same document doesn't create duplicates.
Unique: Implements Celery-based batch processing with idempotent operations and exponential backoff retry logic; provides real-time progress tracking via WebSocket and per-document status visibility; handles embedding failures gracefully without blocking the main application.
vs alternatives: More reliable than synchronous document processing because failures don't block the UI; more scalable than single-threaded processing because Celery distributes work across workers; better observability than fire-and-forget jobs because batch status is tracked throughout the lifecycle.
MaxKB provides a centralized model management interface where users configure LLM providers (OpenAI, Anthropic, Ollama, DeepSeek, Qwen, Llama3) with API keys and model parameters. Credentials are encrypted at rest and never logged. The system validates provider connectivity on configuration and provides fallback options if a provider fails. Model configurations are workspace-scoped, enabling different teams to use different providers.
Unique: Centralizes model provider configuration with encrypted credential storage and workspace-level isolation; supports multiple providers in a single interface with validation and fallback logic; credentials are never logged or exposed in configuration files.
vs alternatives: More secure than storing credentials in environment variables because encryption is enforced; more flexible than single-provider platforms because multiple providers can be configured simultaneously; simpler than building custom credential management because encryption and validation are built-in.
MaxKB provides a visual workflow designer where users compose multi-step AI tasks using nodes (LLM, tool execution, conditional logic, data transformation). The workflow execution engine interprets the node graph, manages state between steps, handles branching based on conditions, and supports error recovery. Workflows can chain LLM calls with tool execution, knowledge base retrieval, and custom code execution in a DAG-like structure.
Unique: Implements a visual node-based workflow system with first-class support for conditional branching, tool execution, and knowledge base retrieval in a single DAG; execution engine manages state across steps and supports error recovery without requiring code changes.
vs alternatives: More accessible than LangChain's agent framework because it provides a visual UI for non-technical users; more flexible than Zapier because it supports LLM-driven logic and custom code execution within the same workflow; better audit trails than custom Python scripts because every step is logged and traceable.
MaxKB allows users to define custom tools by uploading Python code that runs in an isolated sandbox environment. The sandbox uses a C library (sandbox.so) to intercept system calls, preventing malicious code from accessing the filesystem, network, or process management. Tool execution is async and integrated into workflows, allowing LLMs to call custom logic (e.g., database queries, API transformations) safely.
Unique: Uses a custom C-based sandbox library (sandbox.so) with system call interception to isolate Python tool execution, preventing filesystem/network access while maintaining performance; integrated directly into the workflow engine for seamless LLM-to-tool invocation.
vs alternatives: More secure than running untrusted code in a shared Python process because system calls are intercepted at the kernel level; faster than container-based sandboxing (Docker) because there's no container startup overhead; more flexible than pre-built tool libraries because users can define arbitrary Python logic.
MaxKB implements workspace-level multi-tenancy where each workspace has isolated data (knowledge bases, applications, workflows, models). Access control is enforced through role-based permissions (admin, editor, viewer) with granular resource-level checks. User authentication supports LDAP, OAuth2, and local credentials. Workspace membership and permissions are stored in PostgreSQL with audit logging of all permission changes.
Unique: Implements workspace-level multi-tenancy with role-based access control and comprehensive audit logging; supports multiple authentication backends (LDAP, OAuth2, local) without requiring separate identity services; permission checks are enforced at the API layer with granular resource-level control.
vs alternatives: More flexible than Auth0 because it's self-hosted and supports custom LDAP integration; more granular than simple role-based systems because permissions are tracked at the resource level with audit trails; simpler than building custom multi-tenancy because workspace isolation is built into the data model.
MaxKB implements vector-based semantic search using PGVector embeddings combined with optional keyword/BM25 matching for hybrid retrieval. When a user query arrives, it's embedded and compared against indexed paragraphs using cosine similarity. Results are ranked by relevance score and returned with source document metadata. The system supports filtering by document, knowledge base, or custom metadata tags.
Unique: Implements hybrid semantic + keyword search using PGVector with native PostgreSQL integration, enabling fast retrieval without external vector DB dependencies; supports metadata filtering while maintaining semantic relevance through combined scoring.
vs alternatives: Faster than cloud vector DBs (Pinecone) for on-premise deployments because search happens locally in PostgreSQL; more flexible than pure keyword search because it understands semantic meaning; simpler than building custom hybrid search because both vector and keyword indices are managed automatically.
