Everruns vsMastra
Serverless workflows, or a durable engine.
Both are open source and provider-neutral, and both let workflows pause and resume. The difference is the runtime underneath: Everruns is a Rust + PostgreSQL durable engine with no wall-clock ceiling; Mastra is a TypeScript-first framework built to deploy on serverless platforms, where session length lives within their function limits.
Open-source, self-hostable infrastructure your company’s AI agents run on.
A TypeScript-first, serverless agent framework with suspend/resume workflows.
The honest answer
Which should you choose?
Neither is strictly “better” — they optimize for different things. Here’s the straight version.
Use Mastra if…
- Your stack is TypeScript end to end and you want to stay in it.
- You deploy to serverless (Vercel / Cloudflare / Netlify) and like that model.
- You want a lightweight framework rather than a full platform + console.
Use Everruns if…
- You run agents for hours or days and can’t live inside serverless function timeouts.
- You want multi-tenant orgs, budgets, and an operator console in the box.
- You want a fully MIT platform, not an open-core split with proprietary modules.
Side by side
The comparison, dimension by dimension.
| Dimension | Everruns | Mastra |
|---|---|---|
| License | MIT, end to end — runtime and operator console. | Apache-2.0 core, with proprietary enterprise (ee/) modules. |
| Self-host the platform | Runs on your own PostgreSQL. No vendor control plane in the path. | Self-hostable; serverless-first (Vercel, Cloudflare Workers, Netlify). |
| Model providers | OpenAI, Anthropic, Gemini, Bedrock, Fireworks, OpenRouter, Azure — via the Open Responses spec. | Model-agnostic via the Vercel AI SDK. |
| Durable long-running sessions | Rust + PostgreSQL durable engine; every session survives restarts, with no wall-clock ceiling. | Workflows suspend and resume, but run on serverless — session length is bounded by platform function timeouts. |
| Deployment surfaces | Slack, web chat, scheduled jobs, webhooks, A2A, MCP, and a plain HTTP API. | HTTP API and framework integrations; channels are wired up by you. |
| Multi-tenancy & controls | Multi-tenant orgs, permissions, envelope-encrypted secrets, and budgets. | Not a built-in multi-tenant control plane; assembled at the app layer. |
| Operator console | Operator console built in — watch, pause, and operate running agents. | Local dev playground and OpenTelemetry traces; no built-in operator console. |
| Pricing model | Free and self-hostable. Managed Cloud is in development. | OSS core is free; hosted memory runs from free to a per-team monthly plan. |
| Data residency & compliance | Your infrastructure, your database. You hold the state and the keys. | Self-hostable, so residency is yours; formal certifications were still limited as of early 2026. |
The wedge
Where Everruns is different.
A real durable engine, not a timeout
Everruns persists every session in PostgreSQL and resumes after crashes with no wall-clock ceiling. Serverless suspend/resume is elegant, but the runtime still lives inside the host’s function limits.
Platform, not just a framework
Multi-tenant orgs, permissions, envelope-encrypted secrets, budgets, channels, and an operator console ship together — the operational surface you’d otherwise build around a framework.
Fully MIT
The whole platform is MIT — runtime and console. There is no open-core boundary where the parts you need for production sit behind a proprietary license.
Playing fair
Where Mastra is strong.
A comparison you can trust names the other side’s real advantages.
For TypeScript teams, staying in one language with a serverless deploy story is a genuinely smooth path to production.
As a framework, Mastra is quick to drop into an existing app without standing up a platform.
When agents run for hours, the runtime matters.
Everruns is MIT-licensed and self-hostable today — a durable Rust + PostgreSQL engine with no wall-clock ceiling, plus the platform surface around it.
