Why Switch?

Why PostZen vs bundle.social?

PostZen API

Cheaper below about 37 accounts
5 accounts cost $19 on PostZen and $100 on bundle.social. 20 accounts cost $49 against $100. The two meet at 37 accounts, where PostZen Pro plus 17 extras is also $100.
Unlimited posts on every paid plan
Starter, Pro, and Scale have no monthly post cap. bundle.social Pro stops at 10,000 posts a month and Business at 100,000, and each connected account has its own daily ceiling.
No per-account daily caps of our own
PostZen enforces only the limits each network imposes. bundle.social adds plan-based daily caps per account: 5 X posts a day on Free, 15 on Pro, and 18 LinkedIn posts a day on Pro.
Node and Python SDKs
Official SDKs for both runtimes, plus the CLI and MCP server. bundle.social ships a TypeScript SDK and points other languages at the OpenAPI spec.
Published uptime SLA
PostZen commits to 99.97% uptime. bundle.social runs a public status page and a health endpoint but publishes no SLA.
Telegram channels and groups
Post to Telegram alongside Instagram, X, LinkedIn, Facebook, Threads, YouTube, TikTok, Pinterest, and Bluesky. bundle.social does not support Telegram or WhatsApp.

bundle.social

Priced per organization, not per account
Pro is $100 a month and Business is $400, each with unlimited connected accounts. Above roughly 37 accounts this beats PostZen on price, and at 100 accounts it is $100 against PostZen Scale at $149.
Post caps by plan
Free allows 20 posts a month, Pro 10,000, and Business 100,000 across the whole organization. Comments and media uploads have their own monthly caps.
Daily caps per connected account
Each account has a daily posting limit that depends on plan: X is 5, 15, or 15 a day on Free, Pro, and Business; LinkedIn is 10, 18, or 24; YouTube is 10, 10, or 15; Threads is 10, 200, or 250.
X is prepaid and metered
X posts are billed from a prepaid credit balance at $0.015 each, $0.20 with a link, and $0.01 per delete. Analytics and imports on X cost $0.005 each.
Five extra networks, plus a comments API
Reddit, Discord, Slack, Mastodon, Snapchat, and Google Business are supported alongside the majors, and a comments API with first-comment automation shipped in 2026. DM and ads APIs are waitlists.
Rate limits are published and generous
100 requests a second, 500 per 10 seconds, and 2,000 a minute on every plan. PostZen publishes 60 to 2,000 requests a minute by plan, so bundle.social allows more burst on lower tiers.
Analytics kept 30 days
Analytics refresh every 24 hours with 5 forced refreshes a day per team, and are retained for 30 days. Webhook events are kept 7 days and imported posts 30.
TypeScript SDK only
The bundlesocial npm package is the one official SDK. Python, Go, and other languages generate a client from the OpenAPI spec.

FAQ

Common questions

Still have questions?

Is bundle.social cheaper than PostZen?

Only at scale. bundle.social Pro is $100 a month for unlimited accounts and 10,000 posts. PostZen is $19 for 5 accounts and $49 for 20, both with unlimited posts. The two cost the same at 37 accounts. At 100 accounts bundle.social is $100 against PostZen Scale at $149, as long as you stay under 10,000 posts a month.

What are bundle.social’s post limits?

Two kinds. The organization has a monthly cap of 20 posts on Free, 10,000 on Pro, and 100,000 on Business. Each connected account also has a daily cap by plan: for example X allows 5 posts a day on Free and 15 on Pro or Business, LinkedIn allows 10, 18, or 24, and YouTube allows 10, 10, or 15. PostZen paid plans have no monthly cap and only the networks’ own limits apply.

How does bundle.social bill X?

From a prepaid credit balance, at X’s cost: $0.015 per post or reply, $0.20 per post or reply with a link, $0.01 per delete, and $0.005 per analytics call or import. PostZen also passes X API costs through at cost, which is why connecting an X account requires a card on file.

Does bundle.social have a hosted connect flow?

Yes. POST /api/v1/social-account/create-portal-link takes a teamId, the platforms to offer, a redirect URL, and an expiry from 5 minutes to 48 hours, and returns a bundle.social URL that handles OAuth and channel selection. PostZen’s equivalent is the hosted page at /v1/connect/{platform}. Both let your users connect accounts without a login on the vendor.

Which SDKs does bundle.social offer?

One official SDK, the bundlesocial package on npm for TypeScript and Node.js, plus the bundlesocial-cli and bundlesocial-mcp packages. Other languages are expected to generate a client from the OpenAPI spec. PostZen ships Node and Python SDKs, a CLI, and an MCP server with 44 tools.

Does bundle.social have a comments or DM API?

Comments, yes: reading, replying, deleting, and first-comment automation across 11 networks, with monthly caps of 50, 5,000, or 50,000 comments and daily caps per account. DMs and ads are waitlist pages, not shipped features. PostZen does not offer a comments or DM API.

How long does bundle.social keep analytics?

Analytics are refreshed every 24 hours, with 5 forced refreshes a day per team, and retained for 30 days. Webhook events are kept for 7 days, deleted uploads for 7, and imported posts for 30. Build your own store if you need longer history.

Can I migrate from bundle.social to PostZen?

Yes, and the shapes are close. Reconnect each account through PostZen’s hosted OAuth page, replace the x-api-key header with a Bearer key, upload media through /v1/media/presign, and create posts with a platforms array. Accounts on Reddit, Discord, Slack, Mastodon, Snapchat, and Google Business have no PostZen destination, and comment workflows need another tool.

Fewer accounts, more posts?

Start with PostZen if your product connects a handful of accounts per customer and publishes as often as it likes. The API, MCP server, and hosted account connections are on the free plan.
