# The Buffer API alternative for developers & agents.

Buffer is a great dashboard for scheduling by hand. But if you want to post **programmatically**, its API is in beta and geared to personal use, with no agent tooling. PostLake is API-first: an open REST API and a hosted MCP server for every major network, from **$13/month**.

**Short version:** choose **PostLake** if you're a developer or building AI agents and need a real, open API to publish across networks. Stay with **Buffer** if you mainly want a polished dashboard to schedule posts by hand. That's what it's best at.

## PostLake vs Buffer for developers

| | PostLake | Buffer |
| --- | --- | --- |
| Built for | Developers & AI agents | Marketers scheduling in a UI |
| Open public API | Yes: REST + Bearer keys, OAuth | Beta, geared to personal keys |
| Hosted MCP server for agents | Yes | No |
| Pricing model | Usage-based credits (pay per post) | Per channel (~$5/mo each) |
| Starting price | Free, then $13/mo | Free (3 channels), then per channel |
| One normalised response | Yes: one shape for every network | Dashboard-first |
| Social networks | All the majors | 11 |
| Best for | Programmatic posting, agents, apps | Hands-on scheduling by a person |

## Why developers pick PostLake

- **A real, open API.** Create a key and post in minutes over plain REST. No waiting on beta access or app-review gates just to publish a post from your own code.
- **Agent-native out of the box.** A hosted MCP server built for agents, so Claude, ChatGPT or Cursor can publish, schedule and read analytics by being asked. Buffer has no MCP server.
- **Pay per post, not per channel.** Buffer bills per connected channel. Ten channels is about $50/mo before you post. PostLake charges usage-based credits, so connecting more accounts doesn't raise your bill.
- **One response for every network.** Publish to many accounts in one call and get a single normalised shape back, one post id and a per-target result, so your code never branches per platform.

## Where Buffer is the better choice

We'd rather be honest. Buffer is an excellent product for what it's built for:

- **Hands-on scheduling.** If a person wants to sit in a clean dashboard and queue posts, Buffer's UX is polished and hard to beat. PostLake is an API. There's no full marketing dashboard.
- **A genuinely free start for a few channels.** Buffer's free plan covers 3 channels for manual scheduling.
- **Brand and ecosystem.** Buffer is a household name with a large community and lots of integrations aimed at marketers.

## A worked pricing example

Say you connect **10 channels** and post to them from your own app or an agent:

| Scenario: 10 channels | PostLake | Buffer |
| --- | --- | --- |
| How you're billed | Per post (credits) | Per channel (~$5/mo each) |
| Base cost for 10 channels | $0 extra to connect them | ~$50/mo before posting |
| Programmatic + agent access | Included | Limited / not agent-ready |

## Common questions

### Does Buffer have a public API?

Buffer has an API, but it's been limited for new third-party developers. The newer API is in beta and geared to personal keys rather than open third-party OAuth apps. PostLake gives you an open REST API with Bearer keys and OAuth, plus a hosted MCP server, from day one.

### Can I use Buffer with AI agents?

Buffer doesn't ship an MCP server or native agent tooling. PostLake ships a hosted MCP server built for agents that any agent connects to over OAuth, so it can publish, schedule and read analytics by being asked.

### Is PostLake cheaper than Buffer for many accounts?

Often, yes. Buffer charges per channel (about $5/month each on Essentials), so ten channels is roughly $50/month before you post. PostLake charges usage-based credits and doesn't bill per connected account.

### Is PostLake a full replacement for Buffer's dashboard?

Not exactly. Buffer is a polished UI for scheduling by hand, and it's good at that. PostLake is an API and MCP server for developers and agents. Want a human dashboard? Buffer. Want to post programmatically or via an agent? PostLake.
