Analysis

An editorial look at what each product does well and who it suits.

opencode

Slack RTM API

Overall verdict

OpenCode is a solid open-source AI coding assistant that brings terminal-native, model-agnostic development workflows to developers who value flexibility and control over their tooling.

Why this product is good

Open-source and transparent, allowing developers to inspect, modify, and self-host the tool
Model-agnostic design lets you use various LLM providers rather than being locked into a single vendor
Terminal-native workflow integrates smoothly into existing developer environments
Active development and community support keep the tool evolving with new features
Can help automate coding tasks, refactoring, and code understanding directly from the command line

Recommended for

Developers who prefer command-line and terminal-based workflows
Teams and individuals wanting flexibility to choose their own AI model providers
Open-source enthusiasts who value transparency and self-hosting options
Engineers looking to automate repetitive coding tasks and speed up development
Privacy-conscious users who want more control over their data and tooling

Overall verdict

Slack's RTM API is a functional but legacy WebSocket-based method for real-time messaging, largely superseded by the Events API and Socket Mode for most modern use cases, though it still works for simple bot implementations.

Why this product is good

Provides real-time bidirectional communication via WebSocket connection
Simple to understand and implement for basic bot use cases
No need to expose a public HTTP endpoint since it uses outbound WebSocket connections
Well-documented with client libraries available in multiple languages
Works well for low-traffic or personal/hobby bots

Recommended for

Developers building simple internal bots without public server infrastructure
Legacy Slack apps that haven't migrated to newer APIs
Prototyping and testing Slack bot functionality quickly
Small teams needing basic real-time message handling without complex event subscriptions
Users behind firewalls who can't easily expose HTTP endpoints for webhooks

How do I get my bot to read DMs and store the messages in a variable?
Oh, my bad, in that case you probably have to use the Real Time Messaging API for Slack. Source: about 5 years ago
