SecondStack gives an entire organization access to AI without handing its data to third-party clouds.

The platform ships three end-user workspaces โ€” Chat for everyday work, Code for engineering teams, and Agent for automation โ€” running on top of an enterprise LLM gateway that connects to the model providers you choose (OpenAI, Anthropic, Google, and others). Platform and security teams manage everything centrally: who can use which models, what each team spends, and where data lives โ€” inside your own infrastructure.

Because SecondStack is self-hosted, prompts, files, and knowledge bases never leave your environment. For teams that prefer not to operate it themselves, a managed deployment run by the SecondStack team is also available.

Pricing is not per-seat, so rolling AI out to the whole company does not multiply the bill. Deployment and operations are backed by an ISO 27001-certified implementation partner.

    Reliance on a third-party tool for API mocking may create dependencies that could affect project timelines if there are changes in the tool's availability or functionality.

    While suitable for small to medium-sized projects, the tool might not be as scalable for larger projects with extensive API requirements.
  • Learning Curve
    Despite its ease of use, new users may still face some initial learning curve, especially if unfamiliar with Retoolโ€™s overall product suite.

I'm also developing a similar platform called https://postget.dev but this app is in alpha so it's mostly suitable for niche/experimental projects.

  • Retool raises $45M at a $3.2B valuation to improve internal tools
    Ah, we still have a way of generating mock APIs: https://retool.com/api-generator. You can upload a CSV (we'll parse the columns and guess types for each one), and then generate mock data and put it into an AIP for you: https://retool.com/utilities/generate-api-from-csv. In the future, we'd love to make it more robust; we're currently working on a database-y product (think Airtable, but backed by postgres). It... - Source: Hacker News / about 4 years ago
  • Retool Is Reselling Our API Without Permission
    Keep following up! However, your email doesn't seem to be very clear about the situation โ€” it just looks like an offer to sell.
