Open-weight foundation models built for agentic software engineering

As of 29 August 2026, Poolside starts at $0.06/month. Poolside builds open-weight foundation models and coding agents for enterprise software engineering teams. Softwr lists it under AI. Poolside is launched in 2023, available on Web, API, macOS, Windows.

Overview

What Poolside does

Poolside is a foundation model company focused on AI for software development. It develops the Laguna family of open-weight models, including Laguna S 2.1 (118B parameters, 1M context) and Laguna XS 2.1 (33B parameters, 256K context, designed for on-device use), alongside desktop and CLI tools for building with them. The company primarily sells to large enterprises, banks, and government/defense customers with sizeable engineering organizations, while also making models available on usage-based token pricing through platforms like OpenRouter and Vercel AI Gateway.

What people use it for

  • Enterprises deploying AI coding assistance across large developer organizations
  • Government and defense agencies needing on-premise or sovereign coding models
  • Teams building custom coding agents on open-weight foundation models
  • Organizations wanting on-device lightweight coding models

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Poolside.

  • No self-serve public application; access is largely through enterprise sales or third-party model gateways
  • Pricing for the flagship enterprise and government offering is not public and requires a sales conversation
  • Targets organizations with large (5,000+) developer headcounts, making it a poor fit for individuals or small teams
  • Documentation and product surface area are thin compared to consumer-facing coding assistants
