Chaser alternatives for Slack: 6 task trackers compared

If you're looking for Chaser alternatives, you probably like the idea behind Chaser already: tasks start in Slack, each channel works like a project, and the app follows up with whoever owns the work. People usually start looking elsewhere for one of two reasons. Chaser charges per seat with no free plan, or the team wants its Slack tasks to land in a bigger project tool.

This post covers Chaser the Slack task tracker at trychaser.com. The accounts receivable tool at chaserhq.com shares the name and is a separate product.

We build Viably, which is one of the options below, so keep that in mind as you read. For the other five I've stuck to what their own sites and help docs said on November 3, 2026, and I've noted which team each one suits. If you only want to compare Viably and Chaser, the Viably vs Chaser page goes through them feature by feature.

What Chaser does

Chaser creates a task from /chaser or from any Slack message, and its AI picks the due date out of what you type. Your channels act as projects, Chaser follows up with assignees automatically, and you can schedule a status report for each channel. It also has repeating tasks, round robin assignment, checklist templates, time tracking, and a web dashboard with calendar and Kanban views.

Chaser has two plans, and both include every feature:

• Choose Seats: $16 per seat a month, or $11 a month billed annually.
• Full Workspace: $7 per seat a month, billed annually only, with a seat for every member of your Slack workspace.

You get a 14-day trial, after which you pay for one of the two plans. Single-channel guests and external connections use Chaser free.

What to look for in a Chaser alternative

Before you compare tools, decide which of these matter to your team:

1. Capture from the message. The request already exists in a thread, so turning it into a task should take a click or a reaction.
2. Follow-ups you don't have to send. A due date is only useful if something pings the owner when it arrives.
3. Where the list lives. Some tools keep tasks in Slack. Others send them to a separate app, which suits teams that already plan there and adds a login for everyone else.
4. How you pay. Per-seat pricing grows with headcount, and a flat price or a free tier changes the math for larger or smaller teams.

Chaser alternatives at a glance

Prices are in USD as of November 3, 2026, and use the annual rate where a vendor offers one.

Workast

Workast works the most like Chaser of the tools here. You create a task with /todo, with a message shortcut, or by converting a message, and you set the owner and due date in the same step. Workast sends reminders and a daily task list in Slack, and each channel's tasks show up as a checklist there.

The Essential plan is free for unlimited users, keeps tasks in Slack, and includes 100 MB of storage. Standard adds the web app for $39 a month for the first 8 users on annual billing ($47 monthly), plus $4.95 for each user after that. Professional costs $49 a month for 8 users on annual billing.

Who it suits: teams that want Chaser's workflow and a free plan to start on.

Slack Lists

Lists are built into Slack. Any message can go to a list through "Add to list", and each item has a name, an assignee, a due date and a completion checkbox. Assignees see their items under "Assigned to you" and get a notification in Activity.

Lists come with Slack's paid plans and hold up to 1,000 items on Pro and Business+. The free Slack plan doesn't include them. I couldn't find automatic due date follow-ups in Slack's help docs, so expect someone to review the list by hand.

Who it suits: teams already paying for Slack that want a shared checklist without adding an app.

Asana for Slack

Asana's Slack app turns a message into an Asana task with an assignee and due date, inside one of your Asana projects. You can complete and comment on tasks from Slack, send project updates to a channel, and mention @asana to create tasks or ask about them. The tasks themselves live in Asana.

The Personal plan is free for two users. Starter costs $10.99 per user a month on annual billing ($13.49 monthly), and Advanced costs $24.99.

Who it suits: teams that plan their projects in Asana and want Slack to feed requests into it.

ClickUp for Slack

ClickUp creates a task from a slash command or a message's menu, through a form with assignees, status, priority, tags and a due date. You can edit tasks from their previews in Slack and send activity to channels. The tasks live in ClickUp, and the Slack integration works on every ClickUp plan.

Free Forever costs nothing. Core is $9 per user a month on annual billing ($12 monthly), and Business is $17 ($25 monthly).

Who it suits: teams that run docs, projects and tasks in ClickUp and use Slack as a way in.

Trello for Slack

Trello saves a message as a card through "Create card from message", the 📥 reaction, or /trello create. Cards go to your Trello Inbox by default, and /trello link connects a channel to a board. Activity notifications in Slack need the Slack Power-Up on the board.

The free plan covers up to 10 collaborators per Workspace. Standard costs $5 per user a month on annual billing ($6 monthly), and Premium costs $10.

Who it suits: teams that already plan their work on Trello boards.

Viably

Viably is our app. You turn a message into a task by reacting with 📋, from the Create a Task shortcut, or by asking Via, our assistant, in plain words. Each task has an owner, or a Claim button so anyone in the channel can take it. The owner marks it started, blocked or done on the card in the thread. On the due date Viably follows up in the channel and tags the owner. If the task is still open four hours later, Viably tags it overdue, sends the owner a private nudge, and follows up again the next working day. Tasks can repeat daily, on weekdays, weekly or monthly, and they all show up on one board in the dashboard. You can read more about our setup in task management in Slack.

The rest of Viably sits in the same app. Bugs filed with a 🐞 reaction become tracked issues with GitHub sync, and you can attach a medal bounty to a task for whoever finishes it.

The free plan includes every feature, and for as many members as you want. Viably+ costs $269 a month, or $2,560 a year, for the whole workspace at any size, and starts with a 14-day trial. Pricing changes the comparison with Chaser depending on team size. A team of 50 on Chaser's Full Workspace plan paying monthly will set you back $800 a month, several times higher than Viably Plus.

Who it suits: teams that want tasks, bug tracking and recognition in one Slack app at a flat price.

How to choose a Chaser alternative

Start with where your team plans work today. If that's Asana, ClickUp or Trello, their Slack app keeps everything in one place, and you give up the automatic follow-ups Chaser is known for. If your team plans in Slack, the choice is between Workast, Slack Lists and Viably:

• Workast is the closest match to Chaser and has a free plan for unlimited users.
• Slack Lists costs nothing extra if you already pay for Slack, but someone has to keep the list current.
• Viably adds issues, GitHub sync and recognition to tasks, at one price for the workspace.
