Unified BaaS vs. Compose-Your-Own Stack: Head-to-Head
Unified BaaS vs compose-your-own stack: which wins for your project? We compare cost, flexibility, and speed so you can choose with confidence.
Convex is a reactive backend. You write queries, mutations, and actions in TypeScript against its own document-relational database. Powabase gives every project its own Postgres instance with SQL, auth, storage, and realtime, and we manage document ingestion, retrieval, and agents on top. Pick Powabase if your AI app needs SQL and managed RAG. For a TypeScript-first reactive backend, Convex is built for it.

THE SHORT VERSION
COMPARISON TABLE
Powabase: Postgres, its own instance per project
Convex: Convex's own document-relational database
Powabase: SQL from psql, any Postgres driver or ORM, or the generated REST API
Convex: TypeScript query and mutation functions; no SQL
Powabase: GoTrue auth built in, tied to Row Level Security policies
Convex: Clerk, Auth0, or WorkOS AuthKit, or the Convex Auth library (beta)
Powabase: Storage API with public or private buckets
Convex: Built-in file storage
Powabase: Managed: PDF, Word, PowerPoint, Excel, and images via OCR
Convex: Not included; the RAG guide has you extract text from files yourself
Powabase: Managed on upload, with five indexing strategies
Convex: RAG component chunks and embeds the text you add
Powabase: Vector, full-text (BM25), hybrid, and tree search, with an optional reranker
Convex: Vector search from actions and full-text search indexes; you generate the embeddings
Powabase: Managed ReAct agents with built-in, HTTP, and MCP tools, sessions, and approval hooks
Convex: Agent component: agents you define in TypeScript, with threads, tools, and tool approval
Powabase: Supervisor, sequential, and parallel strategies, configured by API
Convex: Workflows you write in code that chain agents
Powabase: Block graphs started by API, webhook, or cron, with a copilot that drafts the graph
Convex: Cron jobs and HTTP actions you write as functions
Powabase: Hosted, OAuth: SQL, auth users, storage, knowledge bases, agents, and workflows
Convex: Local server started with npx convex mcp start
Powabase: Apache-2.0 stack, AI layer included, run with Docker Compose
Convex: Open-source backend under the FSL Apache 2.0 license
WHAT POWABASE ADDS
Upload PDFs, Word, PowerPoint, Excel, or images. Powabase pulls out the text (with OCR for scans), generates the embeddings, and indexes them using one of five strategies. Search by vector, full-text, hybrid, or tree search, with an optional reranker on top.
Read the docs →Agents run a ReAct loop inside your project. Each one gets eight built-in tools plus your own HTTP tools and MCP servers. Runs keep their session history, and a hook can hold a step until a person approves it. You configure them through the API rather than deploying agent code.
Read the docs →Chain agents and other steps into a block graph, then start it by API, by webhook, or on a cron schedule. You can also describe what you want and let the copilot draft the graph.

COEXISTENCE & MIGRATION
Keep your app on Convex and create a Powabase project for document search and agents. A Convex action can make network requests, so call our REST API from there. The Powabase service key stays server-side, never in the browser.
Convex stores documents in tables rather than SQL rows, so start by designing your Postgres tables. Export your data with npx convex export (it writes a ZIP file) and load it into your Powabase project over its Postgres connection. Test on a copy first. Users and stored files move as separate steps. Upload your documents to a knowledge base and Powabase indexes them.[25][4]

An agentic RAG loop's real dependency is a governed RAG backend: pgvector, BM25, metadata, and state on one Postgres, not LangGraph glue.
