## Eraser

Eraser is a technical design platform aimed at the people who document architecture: enterprise architects, DevOps and platform engineers, consultants, and software teams. The core promise is speed without sloppiness, so instead of dragging boxes for hours you describe the system or point Eraser at a source of truth such as code, a cloud account, a CMDB, or a spreadsheet, and it produces a diagram that already follows sensible layout rules.

Beyond static images, Eraser supports interactive maps that zoom from a company-wide view down into a single service, guided explainers that walk teammates through a system, and AI documents for design docs and technical documentation. Team governance features such as shared style presets, naming rules, and reference architectures keep output consistent as more people create diagrams. An open-source agent toolkit and MCP server let tools like Claude, Cursor, and ChatGPT create, search, and export diagrams programmatically.

Prices are organized in tiers that include a free entry point, paid plans, and enterprise agreements, with multi-tenant, single-tenant, and self-hosted deployment options for larger organizations. Security posture includes SOC 2 Type 2 certification and SAML SSO.

**Pricing & Plans:** Freemium with paid plans and custom enterprise pricing. A free tier and free tools such as DiagramGPT are available, while paid individual and team plans plus enterprise agreements cover advanced governance, security, and deployment options; check the pricing page for current rates.

- **AI diagram generation:** Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
- **Maps from live systems:** Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
- **Diagram-as-code integrations:** Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
- **Open-source agent toolkit and MCP server:** Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
- **Team style governance:** Apply presets, naming and notation rules, and reference architectures so every teammate's diagram ships on-brand and consistent.

**Strengths:** Turns prompts, code, and files into properly laid-out diagrams instead of raw box-and-arrow output; Interactive maps and explainers make complex systems understandable to non-architects; MCP server and open-source toolkit fit agent-driven and self-hosted workflows; Enterprise controls such as SSO, SAML, and SOC 2 Type 2 certification

**Limitations:** Heaviest value comes with team and governance features that need setup; Advanced mapping and self-hosted deployment are aimed at larger organizations rather than solo users

## Postly

Postly positions itself as a command center for social publishing: one account to plan, create, approve and schedule posts across the channels a team already uses. Its distinctive angle is agentic operation. You can connect a compatible external AI assistant — the site demonstrates a ChatGPT workflow — brief it on a launch, and receive channel-specific drafts back for review. You keep control of what goes live: content, channels and posting times are all approved before scheduling, and results such as clicks and engagement feed into the next campaign.

For teams that would rather stay in one place, Postly also works standalone with its editor, calendar and built-in AI writing tools. Publishing covers a broad set of destinations including Instagram, Facebook, LinkedIn, TikTok, YouTube, Pinterest, X, Threads, Bluesky, Google Business Profile, Telegram and Slack, subject to plan and connected-account permissions. Approval workflows make it practical for agencies handling multiple client accounts, and analytics show what performed.

Beyond owned channels, Postly adds distribution through people. Brands and publishers can browse creator profiles, compare audience stats and rates, brief a creator and review what goes live, while creators can build a private media kit, set rates and take on sponsored work. In the Creator Campaigns public beta, eligible paid campaigns carry a 7% Postly commission with creators keeping their full agreed fee. Pricing is a publishing subscription with stackable add-ons, and a 14-day Publishing Pro trial is available with a payment card.

**Pricing & Plans:** Freemium with a Publishing Pro subscription paid monthly, plus stackable add-ons such as Campaign Intelligence, AI Studio, API Access and a Custom Telegram Bot. A 14-day Publishing Pro trial is offered when you add a payment card; the plan renews unless cancelled.

- **Agentic AI publishing:** Connect a compatible AI agent, brief it on a campaign, then review and approve channel-specific drafts before Postly schedules them.
- **Multi-platform scheduling:** Plan and publish to Instagram, Facebook, LinkedIn, TikTok, YouTube, Pinterest, X, Threads, Bluesky, Google Business Profile, Telegram, Slack and other supported destinations.
- **Approve-first workflow:** Content, channels and posting times are confirmed by a human before anything goes live, which suits agencies with client approvals.
- **Influencer marketing and creator program:** Find creators by niche and audience stats, agree on a brief and rate, or join as a creator to take sponsored campaigns.
- **Add-on analytics and API:** Optional Campaign Intelligence analytics, AI Studio, API access for programmatic publishing and a custom Telegram bot can be stacked on the subscription.

**Strengths:** Agent-first design lets an AI assistant do the drafting while a human keeps final approval; Supports a wide range of social destinations from one calendar; Approval workflow and client management fit agency use; Creator marketplace and creator program extend reach beyond owned channels

**Limitations:** Feature availability varies by plan, connected account and platform permissions; The creator campaigns marketplace is still in public beta; Best value depends on bundling add-ons, which can complicate cost planning
