InsForge is an open-source AI agent backend with 10,500+ GitHub stars. $25/mo Pro; free tier available. 1.6x faster than Supabase MCP. YC Spring 2026.
InsForge is an open-source backend platform for AI coding agents, backed by Y Combinator Spring 2026 and rated #1 Product of the Day on Product Hunt. It provides PostgreSQL, auth, storage, serverless functions, realtime, and an AI gateway in one MCP-compatible platform. Free tier available; Pro costs $25/month. On MCPMark v2, InsForge uses 2.4x fewer tokens than Supabase MCP with Claude Sonnet 4.6.
InsForge is an open-source backend platform built specifically for AI coding agents. Founded in 2025 by Tony Chang and Hang Huang, backed by $4M pre-seed funding and Y Combinator's Spring 2026 batch, InsForge bundles all seven backend services that a coding agent needs to ship a full-stack application: PostgreSQL database with auto-generated APIs, JWT and OAuth authentication, S3-compatible object storage, serverless edge functions, realtime pub/sub messaging, an AI model gateway, and a vector database powered by pgvector for RAG applications. The platform reached #1 Product of the Day on Product Hunt (March 11, 2026) and has accumulated 10,500+ GitHub stars. The core design insight behind InsForge is that Supabase and Firebase were built for human developers navigating a dashboard. AI coding agents work differently: they need a structured semantic layer they can query for backend state, schemas, deployed functions, and logs, and they need backend operations exposed as tools they can call directly. InsForge exposes all seven backend services through a single MCP (Model Context Protocol) server, compatible with Cursor, Claude Code, GitHub Copilot, Windsurf, Codex, and Cline. On the MCPMark v2 benchmark (21 real-world backend tasks including complex joins, migrations, row-level security, and vector search), InsForge uses 2.4x fewer tokens than Supabase MCP with Claude Sonnet 4.6 and achieves 42.86% Pass4 accuracy versus 33.33% for Supabase. The platform is best suited to developers who use AI coding agents as primary contributors to their codebase. Instead of manually creating Supabase tables, setting up auth flows, and configuring storage buckets, you describe the app to your agent and InsForge's MCP server handles provisioning. Database branching, scoped permissions, and reversible writes let agents test and roll back changes without permanent consequences. One developer built a production application connecting 11 tools and 50+ actions by describing it to an agent, with InsForge handling the entire backend. Pricing has three tiers. Free includes a 500 MB database, 50,000 monthly active users, 5 GB bandwidth, 1 GB storage, and $1 in AI model credits. Projects pause after 1 week of inactivity on the Free tier. Pro at $25/month expands to an 8 GB database, 100,000 MAU, 250 GB bandwidth, 100 GB storage, and $10 in compute credits. Compute is billed separately starting at $5/month for the Nano instance, up to $2,560/month for a 64-vCPU, 128 GB RAM instance. Enterprise pricing is custom with SOC 2, optional HIPAA compliance, SSO, and dedicated support. InsForge is fully open source at github.com/InsForge/InsForge. The 14-person team also maintains an MCP server at github.com/InsForge/insforge-mcp and an insforge-standalone repository for self-hosting. The main limitation compared to Supabase is ecosystem maturity: community tutorials, third-party integrations, and production case studies are still sparse relative to a platform with a decade head start.
Free: 500 MB DB, 50K MAU, 5 GB BW, 1 GB storage, $1 AI credits. Pro: $25/month with 8 GB DB, 100K MAU, 250 GB BW, 100 GB storage, $10 compute credits. Compute billed separately: $5/mo (Nano) to $2,560/mo (64 vCPU). Enterprise: custom pricing with SOC 2 and optional HIPAA.

InsForge has three tiers. The Free plan is $0/month and includes a 500 MB database, 50,000 monthly active users, 5 GB bandwidth, 1 GB file storage, and $1 in AI model credits; projects pause after 1 week of inactivity. The Pro plan costs $25/month and includes an 8 GB database, 100,000 MAU, 250 GB bandwidth, 100 GB storage, and $10 in compute credits. Compute is billed separately starting at $5/month for the Nano instance, scaling to $2,560/month for a 64-vCPU, 128 GB RAM instance. Enterprise is custom pricing with SOC 2, optional HIPAA compliance, SSO, unlimited projects, and dedicated technical support.
InsForge's core features are its MCP server, seven bundled backend services, and benchmark-verified agent performance. The MCP server exposes database operations, auth management, storage, and serverless functions as tools that AI coding agents call directly, eliminating manual dashboard configuration. The seven services are PostgreSQL, JWT and OAuth auth, S3 storage, edge functions, realtime pub/sub, AI model gateway, and pgvector. Database branching with scoped permissions and reversible writes lets agents test changes without permanent consequences. The platform is fully open source at github.com/InsForge/InsForge.
Yes, InsForge has a free tier that includes a 500 MB PostgreSQL database, 50,000 monthly active users, 5 GB bandwidth, 1 GB file storage, and $1 in AI model credits. The main limitation of the Free tier is that projects pause automatically after 1 week of inactivity, making it suitable for prototypes and side projects but not production apps that need 24/7 availability. Upgrading to Pro at $25/month removes the pause and significantly expands all resource limits.
The primary alternative to InsForge is Supabase, which offers similar PostgreSQL-based BaaS with a much larger community and ecosystem but was designed for human developers rather than AI coding agents. Firebase is a strong alternative for mobile and real-time apps, particularly if offline sync is required. Render and Fly.io cover compute and hosting but do not bundle database, auth, and storage into one MCP-native package. For pure AI coding agent workflows, InsForge is the only platform with a published MCPMark benchmark showing 2.4x fewer tokens than Supabase.
InsForge is best for AI-first developers who use Cursor, Claude Code, or Windsurf as their primary coding environment and want their AI agent to provision and manage the backend directly. Startup CTOs building AI-native applications benefit most: instead of manually setting up a Supabase project, the agent handles provisioning end-to-end. InsForge is not appropriate for enterprise teams requiring a mature vendor with 5+ years of production hardening, or for non-technical founders using no-code tools, as direct backend interaction is required.
InsForge ships an MCP (Model Context Protocol) server as its primary API for AI coding agents, available both as a cloud service and as a self-hosted instance at github.com/InsForge/insforge-mcp. The MCP server exposes all backend operations as tools that Cursor, Claude Code, GitHub Copilot, Windsurf, Codex, and Cline can call directly. A traditional REST API is also available for direct integration. The platform supports Anthropic Claude, OpenAI models, and others through its built-in AI model gateway.
InsForge and Supabase both provide PostgreSQL-based backend platforms, but they target fundamentally different operators. Supabase is built for human developers who configure services via a dashboard. InsForge is built for AI coding agents that provision and operate the backend via MCP. On the MCPMark v2 benchmark with Claude Sonnet 4.6, InsForge uses 2.4x fewer tokens, completes tasks 1.27x faster, and achieves 42.86% Pass4 accuracy versus 33.33% for Supabase. Supabase wins on ecosystem maturity, community size, and tutorial availability. InsForge wins specifically for AI-driven development workflows where token efficiency and agent accuracy matter.
