The bundle.social Alternative Built for Agents
bundle.social and Postproxy both put many platforms behind one API with an MCP server. Where Postproxy pulls ahead: pricing is flat and unlimited instead of a metered post pool, and the agent layer runs deep — one-click Claude and ChatGPT connectors (no API key), Cursor, Codex, and Hermes, plus native n8n, Zapier, and Make.
TL;DR
A quick take in two columns, then the detailed comparison below.
bundle.social is a unified API for 15 platforms. Pricing is a monthly post pool — Free (20 posts), Pro $100/mo (10,000), Business $400/mo (100,000). It ships an MCP server and a TypeScript SDK.
Postproxy bills flat — $17/mo (Agentic) is unlimited posts, no metered pool. On top of that it's agent-native: one-click Claude and ChatGPT connectors (sign in, no API key), listed in the Claude directory and MCP registry, plus Cursor, Codex, and Hermes. Add native n8n, Zapier, and Make, a queue system with timeslots and priority, a per-platform failure state machine, Comments + DMs APIs, and 7 typed SDKs.
Side by side
A full breakdown of capabilities, integrations, and API design.
| bundle.social | Postproxy | |
|---|---|---|
| Product type | Unified social media API | Unified social media API |
| MCP server | Yes | Yes |
| One-click Claude / ChatGPT connectors | No | Yes (no API key) |
| Agent client coverage | MCP only | Claude, ChatGPT, Cursor, Codex, Hermes |
| Billing model | Per post (pool) | Per profile / group |
| Posts | Metered (10k–100k by plan) | Unlimited on every plan |
| Paid entry | $100/mo (Pro) | $17/mo (Agentic) |
| Free tier | Yes (20 posts, 3 accounts) | Yes (10 posts/mo) |
| SDKs | 1 (TypeScript) | 7 (Node/TS, Python, Go, Ruby, PHP, Java, .NET) |
| Queue system | Calendar / scheduling | Slots, jitter, priority |
| Failure handling | Not documented | Per-platform state machine |
| n8n / Zapier / Make | No | Native node, Zapier, Make module |
| Comments / DMs API | Comments only | Comments + DMs |
| Webhooks | Yes | Yes (all plans) |
Choose your fighter: profiles vs posts
Postproxy bills per connected profile (or profile group) with unlimited posts. bundle.social bills per post — a monthly pool, plus separate prepaid credits for X. Pick the model that matches your cost driver.
| Scenario | bundle.social | Postproxy |
|---|---|---|
| Billing unit | Per post (pool) | Per profile / group |
| Getting started | Free (20 posts) | Free (10 posts) |
| Up to 10,000 posts/mo | $100/mo (Pro) | $17/mo (Agentic, unl.) |
| Up to 100,000 posts/mo | $400/mo (Business) | $17/mo (Agentic) / $49 (Business) |
This is the real fork. bundle.social bills per post and never charges per account — so if you connect thousands of low-volume accounts, their model can be cheaper. Postproxy bills per profile with unlimited posts — so if post volume is your cost driver, flat pricing wins. Match the meter to your bottleneck.
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. bundle.social ships a bare MCP server.
Flat, unlimited posts
No monthly post pools. $17/mo (Agentic) is unlimited posts across 5 profiles. bundle.social meters posts: 10k on Pro ($100), 100k on Business ($400).
Comments + DMs APIs
Read and reply to comments and DMs across platforms from one API. bundle.social exposes comments but not DMs.
n8n + Zapier + Make
Native n8n node, Zapier, and an official Make module. bundle.social has none of these — MCP and a CLI only.
Queue system
Recurring timeslots with jitter and priority — a real publishing queue, not just a calendar.
Failure handling
Documented per-platform state machine with retry states and per-event webhooks. Critical when machines publish.
Where bundle.social is different
15 platforms
Adds Reddit, Discord, Slack, Mastodon, and Snapchat. If you publish to community platforms Postproxy doesn't cover yet, bundle.social reaches further.
Per-post pricing
You pay per post, not per profile, and connected accounts are unlimited. Spread low or spiky volume across many accounts and that can come out cheaper than a flat per-profile plan.
Which one to use
Different tools solve different problems. Here's how to pick the right one.
Choose bundle.social if:
- You need Reddit, Discord, Slack, Mastodon, or Snapchat
- You connect a very large number of low-volume accounts
- Audience demographics matter most
Choose Postproxy if:
- You're building on agents and want one-click Claude/ChatGPT connectors
- You want flat, unlimited posts with no metered post pools
- You automate with n8n, Zapier, or Make
- You need queue-based publishing with failure recovery and Comments/DMs APIs
