The Outstand Alternative Built for Agents — Start Free
Outstand is a usage-based API for AI agents with no free tier. Postproxy covers the same ground but lets you start free, keeps posts unlimited instead of metered per-post, and layers on a publishing queue with per-platform failure handling, Comments and DMs APIs, and one-click Claude/ChatGPT connectors.
TL;DR
A quick take in two columns, then the detailed comparison below.
Outstand is a unified API for 12 platforms aimed at AI agents, on a single usage-based plan: $19/mo includes 3,000 posts, then $0.007 per post to 10K and $0.005 beyond — no free tier. It exposes an MCP server (28 tools) and integrates over REST.
Postproxy starts free and keeps posts flat and unlimited — no per-post overage. It adds a queue system with timeslots and priority, a per-platform failure state machine, and Comments and DMs APIs beyond publish-and-analytics. It's also agent-native: one-click Claude and ChatGPT connectors (sign in, no API key), listed in the Claude directory and MCP registry, plus Cursor, Codex, Hermes, and 7 typed SDKs.
Side by side
A full breakdown of capabilities, integrations, and API design.

| Billing model | Per post | Per profile / group |
| Posts | Metered ($19 + overage) | Unlimited on every plan |
| Free tier | No ($19/mo minimum) | Yes (10 posts/mo) |
| Paid entry | $19/mo (3,000 posts) | $17/mo (unlimited) |
| SDKs | REST only (no typed SDKs) | 7 (Node/TS, Python, Go, Ruby, PHP, Java, .NET) |
| Queue system | No (scheduledAt only) | Slots, jitter, priority |

Choose your fighter: profiles vs posts
Postproxy bills per connected profile with unlimited posts, and you can start free. Outstand bills per post — $19/mo for 3,000, then overage, with no free tier.
| Volume | Outstand | Postproxy |
|---|---|---|
| Billing unit | Per post | Per profile / group |
| Try it | No free tier | Free (10 posts/mo) |
| Up to 3,000 posts/mo | $19/mo | $17/mo (Agentic, unl.) |
| 10,000 posts/mo | ~$68/mo | $17/mo |
| 50,000 posts/mo | ~$268/mo | $17/mo |
| 100,000 posts/mo | ~$518/mo | $17/mo |
Same fork: Outstand meters posts, Postproxy meters profiles. Outstand's included 3,000 posts make $19 reasonable at low volume, but there's no free tier to prototype against and the per-post overage compounds — 100,000 posts is roughly $518/mo. Postproxy is flat: $17/mo (Agentic) is unlimited posts across 5 profiles, and you can build the whole integration on the free tier first.
Where Postproxy wins
APIs, SDKs, tenant isolation, and predictable behavior—without running publishing infrastructure yourself.
Ready for agentic setups
One-click Claude & ChatGPT connectors (sign in, no API key), listed in the Claude directory and MCP registry, plus Cursor, Codex, Hermes, and skills. Outstand ships a bare MCP server.
Start free
Prototype the full API without a credit card. Outstand has no free tier — $19/mo minimum.
Flat, unlimited posts
No per-post overage. 100,000 posts is ~$518/mo on Outstand; $17/mo flat on Postproxy (Agentic).
n8n + Zapier + Make
Native n8n node, Zapier, and an official Make module. Outstand is MCP + REST only.
Queue system
Recurring timeslots with jitter and priority — beyond a single scheduledAt field.
Engagement APIs
Comments and DMs APIs, not just publish and analytics. Read, reply, and moderate across platforms.
Where Outstand is different
Pay-per-post pricing
You pay per post, not per profile. At low or spiky volume, usage-based billing can come out cheaper than a flat plan — you only pay for what you actually send.
Niche platforms like Vimeo
Covers Vimeo and Reddit, which Postproxy doesn't yet. If your distribution includes those specific platforms, Outstand reaches ones we don't.
Which one to use
Different tools solve different problems. Here's how to pick the right one.
Choose Outstand if:
- You publish at low or spiky volume and prefer pay-per-post pricing
- You need niche platforms like Vimeo or Reddit
- You want built-in rate-limit handling at very high throughput
Choose Postproxy if:
- You're building on agents and want one-click Claude/ChatGPT connectors
- You want to start free and flat unlimited posts instead of per-post overage
- You automate with n8n, Zapier, or Make
- You need queues, failure recovery, and Comments/DMs APIs
