I've developed a SaaS starter that prioritizes best practices: - Backend built with hexagonal architecture - Frontend structured with the Refine framework
It offers a comprehensive set of features: ๐ Multi-tenancy support ๐ณ Seamless integration with Stripe for payments ๐ Infrastructure as Code for Render or Vercel deployment ๐ User authentication and authorization ๐ Smooth sign-in and sign-up flows ๐ Easy creation of CRUD pages with filters
The tech stack includes Next Auth, Nest.js, Prisma, Zod and GraphQL.

Emisar is the last MCP server youโll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ and every call is recorded.

Widin.io's answer
We use the Refine framework to help you easily create advanced and organized frontend features.
On the backend, we structure the codebase using Hexagonal Architecture best practices. This approach is crucial for a SaaS platform to effectively deliver advanced features.
Emisar.dev's answer:
emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [
Widin.io's answer
Widin is the only starter that focuses on hexagonal architectures. It helps to start quickly but also to stay on the right track over time.
Emisar.dev's answer:
Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.

Startup CTO launching a new product.
Emisar.dev's answer:
emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.
Widin.io's answer
Having built several SaaS web apps from scratch, I developed over and over similar features. Trade-off between velocity and clean architecture are sometime made, while undesirable. Widin aims to provide a solution to that compromise.
Emisar.dev's answer:
Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.

Next.js, React.js, Typescript, Refine, Next Auth, GraphQL, GraphQL Codegen, Nest.js, Passport, CASL, Zod, Prisma, PostgreSQL, Vercel, Render.
Emisar.dev's answer:
The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.
