Slackgreen.com vs Slack.green vs NotAway: What Is the Difference?

First, an important clarification: Slackgreen.com and Slack.green are separate products. They have similar names and both advertise Slack presence tools, but they have different websites, pricing, documentation, and feature sets. NotAway is a third service with a $3.99 monthly plan covering up to seven workspaces.

All three aim to solve the same underlying problem: Slack can show an inaccurate away indicator during legitimate work outside the app. This guide compares only features each service publicly documents as of July 29, 2026. It does not treat promises such as “100% safe” or “your boss will never know” as independently verified facts.

Slackgreen.com: The $59 Lifetime Chatbot Service

Slackgreen.com describes its product as a chatbot that can make your Slack availability green whether or not the Slack client is running. It advertises schedule and timezone controls, no required browser extension, and a monthly statistics email. Its current public offer is $59 for lifetime access with a seven-day refund period.

The product page explains the benefit clearly but leaves several purchasing questions unanswered. It does not publish a workspace allowance, detailed connection workflow, or a visible feature-by-feature plan table. Its terms say the service may be modified, suspended, or discontinued, which is a relevant consideration for any lifetime purchase.

Best for

Someone comfortable with a one-time purchase who needs a basic scheduled Slack service and receives confirmation from the vendor that their required workspaces are supported.

Slack.green: A Newer Cloud Service and Self-Hosted CLI

Slack.green publishes considerably more technical documentation. Its hosted service runs in the cloud, supports custom schedules, and lets users connect a workspace through a Chrome extension or by manually supplying Slack browser tokens. Its documentation says the free plan supports up to three workspaces, while Pro and the CLI support unlimited workspaces.

The self-hosted CLI is a different operational model. It currently costs $79 once, requires Python 3.11 or newer, stores encrypted tokens locally, and runs a background daemon. On a laptop it stops when that computer shuts down; users can install it on a remote server or choose the hosted service instead. This is powerful, but it also makes the owner responsible for the machine and process when self-hosting.

Slack.green is the closest competitor in this comparison. Its free three-workspace plan and unlimited CLI are meaningful advantages. Its site also makes absolute safety and detectability claims that should be understood as the vendor's marketing claims, not guarantees provided by Slack.

Best for

Someone who wants a free hosted tier for three or fewer workspaces, or a technical user who prefers an unlimited self-hosted command-line tool and is willing to maintain it.

NotAway: Managed Cloud Presence for Up to Seven Workspaces

NotAway focuses on one managed plan instead of mixing a free hosted tier, lifetime cloud offer, and local CLI. For $3.99 per month, users can connect up to seven Slack workspaces, configure active days, start and end times, and an IANA timezone, then see connection and schedule state in one dashboard.

Because NotAway runs in the cloud, the computer used for setup does not have to remain awake. More importantly, workspace health is part of the product: when Slack credentials expire or become invalid, NotAway records the sync problem and sends a credential-refresh email. That is useful when several clients depend on the same schedule.

Best for

Freelancers, consultants, agency workers, and people with several client Slack accounts who want a managed service, a clearly documented seven-workspace allowance, and no local daemon or server to maintain.

Pricing: Which Is Actually Cheaper?

Slack.green's free tier is the cheapest option for up to three workspaces. Slack.green's $79 CLI and Slackgreen.com's $59 lifetime offer can both cost less than a recurring service over a long enough period. NotAway's monthly plan costs $47.88 across twelve individual monthly payments.

Price alone misses the operational difference. Self-hosting can require an always-on laptop or paid remote server. A lifetime cloud offer transfers availability risk to a service whose future operating costs still exist. A monthly managed service costs more over several years, but also gives the provider a continuing reason to maintain hosting, support, monitoring, and compatibility.

Security and Privacy Trade-Off

Cloud Slack-presence services need credentials capable of maintaining the connection. That is more sensitive than a local mouse utility. Review the privacy policy, remove a connection when it is no longer needed, and refresh credentials if the underlying Slack session changes. A self-hosted tool keeps tokens on your machine but shifts security and availability responsibility to you.

NotAway's connection extension creates an encrypted, short-lived code on the user's device. The user chooses to paste that code into NotAway; the extension does not retain it. NotAway stores the submitted Slack session credentials while the workspace is connected so its cloud worker can maintain the requested schedule. This trade-off is stated directly rather than hidden behind an absolute safety promise.

Final Verdict

• Choose Slackgreen.com if the vendor confirms your workspace needs and you value its $59 lifetime offer.
• Choose Slack.green for its free three-workspace tier or if you want to operate an unlimited self-hosted CLI.
• Choose NotAway for the clearest managed package: up to seven workspaces, cloud scheduling, connection status, and refresh alerts for $3.99 monthly.

If you are simply fighting the occasional Slack away status, a free local method may be enough. If you want to keep Slack active across several organizations without keeping a computer on, NotAway offers the most straightforward middle ground. It keeps the Slack green dot tied to the schedule you choose rather than to a moving mouse.
