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 Durable Workflow Engines for Production in 2026
A ranked list of the best durable workflow engines for production deployments in 2026. Durable workflow engines persist execution state to a database so that long-running workflows survive process restarts, deployments, and infrastructure failures. The ranking covers Temporal, Prefect, Apache Airflow, Camunda, Windmill, and n8n. Tools were evaluated on production reliability, developer experience, scalability, open-source health, and documentation quality. The shortlist intentionally mixes code-first engines (Temporal, Prefect, Airflow) with hybrid visual platforms (Camunda, Windmill, n8n) to reflect how production teams actually choose workflow engines in 2026.
Best No-Code Automation Platforms in 2026
A ranked list of no-code automation platforms in 2026. The ranking covers visual workflow builders that allow non-engineering teams to connect SaaS apps, route data, and add conditional logic without writing code. Entries cover proprietary cloud platforms (Zapier, Make, Pipedream, IFTTT) and open-source visual builders (n8n, Activepieces). Scoring reflects integration breadth, pricing accessibility, visual editor ease, reliability and error handling, and self-hosting availability.
