How much does Slack cost in 2026?
Quick Answer: Slack pricing as of July 2026: Free (90-day history, 10 integrations), Pro $7.25/user/month billed annually ($8.75 monthly), Business+ $15/user/month billed annually ($18 monthly, with AI features included), and Enterprise+ (custom, replacing Enterprise Grid). The standalone Slack AI add-on has been discontinued — its features now sit inside Business+ and above. A 100-user Pro team costs $725/month annually. Microsoft Teams is included with M365 at no extra cost.
Slack Pricing (as of July 2026)
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | 90-day message history, 10 integrations, 1:1 huddles, basic Workflow Builder |
| Pro | $7.25/user/mo billed annually ($8.75 monthly) | Full message history, unlimited integrations, group huddles, advanced Workflow Builder |
| Business+ | $15/user/mo billed annually ($18 monthly) | SSO/SAML, compliance exports, included AI features, 99.99% uptime SLA |
| Enterprise+ | Custom | Multi-workspace, DLP, eDiscovery, HIPAA eligible, custom retention |
Two 2026 changes matter. The top tier is now Enterprise+ (it replaced Enterprise Grid), and Business+ rose to $15/user/month on annual billing (from $12.50). Annual billing on Pro saves about 14% versus the $8.75 monthly rate.
Free Plan Limitations
| Feature | Free | Pro |
|---|---|---|
| Message history | 90 days | Unlimited |
| Integrations | 10 | Unlimited |
| File storage | 5 GB/workspace | 10 GB/member |
| Huddles | 1:1 only | Group (up to 50) |
| Workflow Builder | Basic | Advanced |
The 90-day message-history limit is the most impactful restriction. Messages older than 90 days are hidden (not deleted) and reappear on upgrade.
Cost at Scale
| Team Size | Pro /mo | Business+ /mo | Annual Pro | Annual Business+ |
|---|---|---|---|---|
| 10 users | $73 | $150 | $870/yr | $1,800/yr |
| 25 users | $181 | $375 | $2,175/yr | $4,500/yr |
| 50 users | $363 | $750 | $4,350/yr | $9,000/yr |
| 100 users | $725 | $1,500 | $8,700/yr | $18,000/yr |
| 500 users | $3,625 | $7,500 | $43,500/yr | $90,000/yr |
Slack AI
The standalone Slack AI add-on (launched 2024) has been discontinued — it is no longer sold as a separate $10/user line item. AI features (AI search, conversation summaries, channel recaps, thread digests) are now included in Business+ and above, which makes Business+ at $15/user the effective floor for teams that need Slack's AI.
Slack vs Microsoft Teams Cost
| Scenario | Slack | Microsoft Teams (in M365 Business Basic) |
|---|---|---|
| 50 users — messaging only (Pro) | $363/mo | $300/mo ($6/user, includes Teams + web Office apps) |
| 50 users — messaging + AI | $750/mo (Business+, AI included) | $300/mo (Copilot AI add-on $30/user extra) |
| Effective messaging cost for M365 users | added tool | $0 (already included) |
For organisations already on Microsoft 365, Teams is included at no additional cost, making Slack an added expense. For organisations not on Microsoft 365, Slack Pro's $7.25/user is competitive.
Editor's Note: We evaluated Slack Pro vs Microsoft Teams for a 200-person consulting firm. Slack Pro cost about $1,450/month ($17,400/year). The firm was already on Microsoft 365 Business Standard, which includes Teams, so company-wide Slack would have been additive. We recommended Teams for messaging and Slack for a 30-person engineering team that needed the GitHub/Jira integrations Teams lacked — about $217/month for 30 Pro seats, saving roughly $14,790/year versus company-wide Slack.
Editor's Note: Across ShadowGen Slack rollouts in 2024-26, the per-active-user model sounds protective and rarely saves much. A member counts as billable if they take any action in a rolling 28-day window, so in practice a "200-seat" workspace bills close to 200 every cycle. The saving that is real comes from hygiene: on one client we cut the monthly bill by promptly deactivating departed and seasonal staff who were still counting as active. Re-checked July 2026: the standalone Slack AI add-on has been retired and Business+ has risen to $15 a user, so any team that wants the real AI features now buys Business+ rather than bolting AI onto Pro. — Rafal Fila, ShadowGen

Best Human-in-the-Loop Automation Platforms 2026
Eight platforms are ranked here on a single mechanism: how a person enters an automated path, and what the system can prove afterward about the decision they made. Moxo scores 7.7 and ranks first; Camunda 8 scores 7.2, Microsoft Power Automate 7.1, Pega 6.9, n8n 6.7, Zapier 5.9, Kissflow 5.8 and ServiceNow 4.8, scored 22 September 2026 on the five weighted criteria. Those criteria cover the step type, the approver's account or licence, the routes available on a rejection, the audit record, and the meter that charges for the decision, and none of them can tell a review from a rubber stamp, so the methodology adds a check readers can run on any product in a few minutes: whether the decision record tells a considered approval from an instant one. Every figure was read from a vendor-owned surface and carries its own date.
Best Automation Platforms for AI Orchestration 2026
This ranking answers one question: how many real business applications can an AI agent act on out of the box? It evaluates nine platforms as of August 2026 on the reach they give an agent, not on the workflow logic they can express. That boundary is deliberate, because two neighbouring pages on this site answer different questions. Best Process Orchestration Platforms 2026 scores multi-step process control, error handling and state management. Best AI Agent Platforms 2026 scores building and hosting the agent itself. This page scores the layer between them: the connective tissue that lets an agent already built elsewhere reach the applications a business actually runs on. A platform that leads one of those pages can place low here, and two of them do. Scores derive from application and action catalogue counts, the exposure model each platform uses to publish those catalogues to an agent, setup effort, failure handling and cost per agent action. Every figure was retrieved from a vendor-owned surface on 11 August 2026 unless an earlier date is stated against it.

Moxo vs Lindy in 2026: Who Presses Approve When the Agent Asks
Lindy, founded in 2023, sells an AI teammate that lives in Slack and in each person's inbox; Moxo, whose predecessor Moxtra was co-founded in 2012, runs multi-party processes where approvals are steps only a person can close. Moxo wins three rounds to two: who closes the step, work across companies and the record. Lindy wins reach and testing. Vendor pages and docs read 28 September 2026.
Moxo vs Kissflow in 2026: What an Outside Approver Costs, and What the Record Proves
Moxo and Kissflow both sell approvals to people who do not write code, and each wins one round outright: Moxo's Web and Headless SDKs run the approval inside the buyer's own product, under the buyer's own sign-in. Kissflow's portal audit log stamps every event with an actor, a device and an IP, where Moxo publishes no field list. Both answers are quoted, not priced, and both meters punish a one-step request sent to hundreds of clients. Cost, the decision record, rejection routes, AI metering and governance, verified 14 to 23 September 2026.
Moxo vs Camunda 8 in 2026: BPMN User Tasks for Staff, Step Types for Outsiders
Camunda 8 can fix a process under cases already running, since active instances migrate onto a corrected definition and, for Camunda user tasks, "a migrated active user task remains assigned to the same user". Moxo keeps the shared queue that Camunda's Tasklist V2 stops evaluating, with desks that are "a shared inbox that multiple users can pick work from". Those are the two knockouts in a fight Moxo takes three rounds to two, with one section left unscored. Portability, AI review gates and a published price decide the rest, verified 14 to 23 September 2026.
