xpander.ai

Teams building AI agents that live inside Slack, and tired of writing the plumbing around them, are the people xpander.ai is made for. xpander.ai is a backend-as-a-service for deploying and managing Slack-native AI agents, and it covers the infrastructure and scaling work so you can get an agent running in minutes.

It works with any AI framework or a custom agent implementation.

The plumbing it takes over is specific.

Built-in OAuth handles user authentication for SaaS platforms.

Thread context and session tracking are managed automatically, and context window usage is optimized to avoid overflow in long conversations.

Voice, images and files are converted into clean text before the agent sees them.

Slack rate limits are handled, and requests are batched to prevent errors and cut API costs.

On spending, its Smart Engage feature pre-screens messages and is claimed to save 80% or more on LLM costs.

Security is listed as SOC 2 Type II compliant and GDPR ready.

Pricing is enterprise, so expect to talk to the team rather than sign up on a card.
