Technical Project Manager Information Technology and Services Mid-Market (51-1000 emp.) 8/14/2026 "Slack’s Threading and APIs Make Automation and Async Collaboration Effortless" 4.5/5 What do you like best about Slack? The threading model, paired with a solid Search/Web API, is what keeps me on Slack over alternatives. Being able to pull conversation history programmatically (conversations.history, search.messages) lets me build internal tooling—alert routing, incident bots, deploy notifications—without having to fight the platform. Workflow Builder handles the simpler automations, and for anything more complex, the Bolt SDK (Python/JS) offers sensible event subscriptions and a rate-limit model that feels reasonable compared to other chat APIs I’ve integrated with. Custom emoji and reactions also work well as lightweight status signals in engineering channels (build passing/failing, PR needs review). It’s a small thing, but it genuinely speeds up async communication across a distributed team. Review collected by and hosted on G2.com. What do you dislike about Slack? Slack stands out for me because it makes day-to-day workplace communication much more organized and efficient. The interface is clean and intuitive, so it’s easy to move between channels, direct messages, threads, and shared files without feeling overwhelmed. I also find the search functionality very useful when I need to quickly find an old conversation, document, or specific piece of information. Another strong point is the wide range of integrations with other tools. Being able to connect Slack with the applications I already use helps centralize updates and notifications and reduces the need to constantly switch between different platforms. Performance is also reliable for regular team communication, even when there are many active conversations and notifications. Overall, Slack helps keep collaboration structured, improves communication across projects, and makes it easier to keep track of work without adding unnecessary complexity. Review collected by and hosted on G2.com. What problems is Slack solving and how is that benefiting you? Slack addresses the problem of scattered workplace communication by bringing team conversations, project discussions, files, updates, and notifications into one centralized platform. Rather than relying on long email threads or constantly switching between different communication tools, I can keep discussions organized by channel and connect with the right people in the right context. For me, this makes collaboration faster and more transparent. It’s easier to track project updates, locate past decisions or shared information, and get quick feedback without disrupting my workflow. The integrations with other tools are also valuable, since important notifications and updates can be delivered directly into Slack. Overall, it cuts down on communication overhead, improves coordination across projects, and helps me stay focused on my work. Review collected by and hosted on G2.com.
