## 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

## Phare

Phare bundles the pieces teams normally stitch together from several vendors: uptime checks, alert routing, incident tracking and public status pages. Monitors can target HTTP(S) endpoints, TCP ports or ICMP pings, and checks run from a dozen regions across Europe, Asia, America and Oceania, so you can distinguish a genuine outage from a regional routing problem. Per-monitor assertions on status codes, response bodies and SSL certificate expiry make failure conditions explicit rather than inferred.

When something breaks, Phare opens an incident automatically with confirmation thresholds and region-based rules to suppress one-off blips. Incident timelines collect comments and updates, AI-generated summaries and postmortem drafts cut down on writing, and updates can be published straight to a status page. Maintenance windows let you pause checks or mute notifications during planned deploys so SLA reports stay clean.

Phare is made, hosted and incorporated in the European Union. Servers run on Hetzner in Germany with Bunny.net as CDN and Scaleway for email, and the company positions itself against tracking cookies — there are no analytics pixels on the product. A developer-first surface includes a REST API, Terraform-friendly resource definitions, documentation and an MCP server so AI assistants can manage monitors directly. Phare also runs a Phare for Good programme giving free access to open-source projects and nonprofits.

**Pricing & Plans:** Freemium with usage-based tiers. The Hobby plan is free (100,000 monitoring events/month, 10 AI summaries, unlimited projects and public status pages). The Scale plan starts at 5€/month with 500,000 events and 100 AI summaries included, plus overage billing per extra event, summary or SMS alert. A Custom Enterprise add-on adds SLAs, volume discounts and major commitments.

- **Multi-region infrastructure checks:** Monitor HTTP(S), TCP and ICMP targets on intervals as short as 30 seconds from 12 locations across Europe, Asia, America and Oceania, with per-region confirmation rules to avoid false alarms.
- **Incident management with AI summaries:** Outages become tracked incidents with full event timelines, comments and updates; AI drafts incident summaries and postmortem text so teams can focus on the fix.
- **Branded status pages:** Publish public or private status pages on your own domain with SSL, subscriptions via RSS, Atom and Slack, and IP, token or password gating.
- **Flexible alert routing:** Send notifications by email, SMS, voice, Slack, Discord or outgoing webhooks, with alert rules that keep noise out of on-call rotations.
- **Developer and automation surface:** Manage everything through a REST API, configuration-as-code resources, documentation and an MCP server that lets AI assistants query and control monitors.

**Strengths:** Checks every 30 seconds from a broad set of global regions at a low entry price.; Monitoring, incident management and status pages come from a single platform.; European data hosting with no marketing trackers on the product.; Public open metrics and a founder-led support model with same-day answers.

**Limitations:** SMS and voice alerts are only included from the Scale plan upward.; The interface assumes some familiarity with HTTP, SSL and server concepts.; Full webhook and API automation is aimed at technically comfortable users rather than non-developers.
