strengths
- 1Free plan. 3 channels with 10 scheduled posts each, free forever. PostFast only offers a 7-day free trial.

- 3Mastodon support. Buffer supports Mastodon, which PostFast doesn't.
- 4Start Page. Built-in link-in-bio tool with analytics. PostFast doesn't offer this.
- 5Browser extension. Share content directly from any webpage. PostFast doesn't have a browser extension.
- 6RSS feeds. Built-in content discovery from blogs and news sources. PostFast requires n8n/Zapier for RSS workflows.
- 7Established ecosystem. 15+ years in the market, integrations with Canva, Pocket, Feedly, WordPress, and more.
strengths
- 1Flat pricing at scale. PostFast Growth gives you 30 accounts for €40/mo on annual billing. The same 25 accounts on Buffer costs $125–250/mo on annual billing. At 100 accounts, PostFast Pro costs €82.50/mo on annual vs Buffer's $500–1,000/mo.
- 2Production REST API without request-cap tiers. Full CRUD operations, batch posting (up to 15 posts), comprehensive endpoint coverage.

- 6Telegram support. Native support for Telegram channels and groups with text (up to 4096 chars), images, videos, and mixed media.
- 7LinkedIn document posts. Publish PDFs, PowerPoint, and Word documents directly to LinkedIn - something Buffer doesn't support.
- 8Approval workflows on all plans. Multi-user workspaces with content approval included from Starter. Buffer restricts approvals to the Team plan ($10/channel/mo annual).
- 9White-label workspace branding. Add your own logo to workspaces. Buffer has no white-label features.

Switching from Buffer to PostFast takes minutes. Connect your social accounts via OAuth (same platforms), and start scheduling. If you use Buffer's API, PostFast's REST API covers the same operations with a simpler authentication model. For bulk content, use PostFast's Zapier or n8n integration to automate your migration workflow. Your existing Buffer account can stay active during the transition - there's no need to disconnect anything until you're ready.

Common questions about PostFast vs Buffer, answered.
Is Buffer better than PostFast?
Buffer is better if you need a free plan for 3 or fewer channels, or if you rely on built-in AI caption generation. PostFast is better for scaling beyond 5 accounts - its flat pricing saves 50–90% compared to Buffer's per-channel model. PostFast also offers Telegram support that Buffer lacks, plus a REST API without Buffer's per-plan request caps and an MCP server with 13 tools on every plan.
How much does Buffer cost vs PostFast?
Buffer charges per channel: $5/channel/mo billed annually ($6 monthly) for Essentials, or $10/channel/mo billed annually ($12 monthly) for Team. PostFast uses flat plans on annual billing: €10/mo for 4 accounts (Starter), €24/mo for 12 accounts (Creator), €40/mo for 30 accounts (Growth), €82.50/mo for 120 accounts (Pro). At 12 accounts, PostFast Creator (€24/mo on annual) costs about 40% of Buffer Essentials ($60/mo annual).
Can I switch from Buffer to PostFast?
Yes. Connect your social accounts via OAuth in PostFast, and start scheduling immediately. Both tools support the same major platforms. If you use Buffer's API, PostFast's REST API provides equivalent functionality. You can run both tools in parallel during the transition.
Does PostFast have a free plan?
PostFast offers a 7-day free trial on all plans with no credit card required. Unlike Buffer's permanent free tier (3 channels, 10 posts each), PostFast focuses on full-featured paid plans starting at €10/mo on annual (€12/mo monthly) for 4 accounts.
Which tool is better for agencies?
PostFast Pro (€82.50/mo on annual) supports 120 accounts with approval workflows, white-label branding, and API access - ideal for agencies. Buffer's equivalent capacity would cost $600/month on Essentials or $1,200/month on Team at $5/$10 per channel on annual billing, and approval workflows require the more expensive Team plan.
Does Buffer have an API?
Yes. Buffer's API is generally available on all plans, including Free, with public developer docs. Limits scale by plan: Free gets 1 API key and 3,000 requests/month, Essentials 3 keys and 7,500 requests/month, Team 5 keys and 15,000 requests/month, and every tier is throttled at 100 requests per 15 minutes. PostFast offers a production-ready REST API with full CRUD operations, batch posting (up to 15 posts), and comprehensive documentation on all plans, without request-cap tiers.
