About FastAPI and AscendCore

In their own words, as submitted to SaaSHub.

FastAPI
AscendCore

No description of FastAPI yet.

AscendCore is agentic AI for the L1 IT help desk that resolves tickets, not just chats about them. Two properties define it. It is deterministic: every request runs a versioned, auditable runbook held in source control, never free-form model output. And it is approval-first: nothing touches a...

Features and specs

What each product offers, as listed by its team.

FastAPI 7 features
AscendCore 7 features
  • High Performance
    Built on Starlette and Pydantic, FastAPI is one of the fastest frameworks for Python, providing high performance due to its asynchronous request handling.
  • Automatic Interactive API Documentation
    FastAPI automatically generates interactive API documentation via Swagger UI and ReDoc, which are very helpful for development and testing.
  • Type Checking and Validation
    With Pydantic models and Python type hints, FastAPI provides automatic data validation and type checking, reducing the chance of runtime errors.
  • Ease of Use
    Its syntax and design make it easy to learn for Python developers, offering a smooth development experience while reducing boilerplate code.
  • Asynchronous Support
    FastAPI supports asynchronous programming, allowing for better performance for I/O-bound operations, making it optimal for handling many simultaneous connections.
  • Extensive Documentation
    It has comprehensive and well-structured documentation, which is very useful for both beginners and advanced users.
  • Community and Ecosystem
    FastAPI has a growing community and ecosystem, with many plugins and integrations available to extend its functionality.

Possible disadvantages

  • Learning Curve for Asynchronous Programming
    Although FastAPI itself is easy to learn, grasping the concepts of asynchronous programming in Python can be challenging for beginners.
  • Complex Dependencies
    Using Pydantic for advanced validation can make the request models complex, requiring a deeper understanding of Pydantic and its functionalities.
  • Early Stage Libraries
    Some third-party libraries and extensions specifically tailored for FastAPI might still be in early stages of development and lack long-term stability.
  • Limited Real-World Examples
    Although the documentation is extensive, there might be limited real-world examples and case studies readily available compared to more mature frameworks.
  • Deployment Complexity
    Deploying FastAPI applications might be more complex in comparison to traditional synchronous frameworks, mainly due to the need for asynchronous server setups.
  • Approval gate
    Every automated action requires explicit human approval before it runs. No autonomous actions.
  • Production runbooks
    31 live runbooks across identity, access, endpoint and provisioning
  • Audit trail
    SHA-256 tamper-evident chain, customer-exportable and independently verifiable
  • Integrations
    Okta, Microsoft Entra ID, Microsoft 365, Intune, Slack, Teams, Jira Service Management, Confluence, ServiceNow
  • Agent Gateway
    AI agents propose runbook actions through an approval-gated MCP gateway. Nothing executes without a human decision.
  • Access Reviews
    Access review campaigns with approval-gated revocation and exportable evidence bundles for audit
  • Savings Ledger
    License reclaim tracked as an auditable savings ledger, so recovered spend is evidenced rather than estimated

Questions & Answers

As answered by people managing FastAPI and AscendCore.

What makes your product unique?

AscendCore's answer:

AscendCore is approval-first: the AI never executes anything. It classifies intent, then a named human approves or denies on an interactive card in Slack or Microsoft Teams, and only then does a deterministic runbook run. The classifier holds no credentials and has no execution path.

Every approval and execution is appended to a SHA-256 hash chain in which each record contains the prior record's hash. Customers can export that chain and re-hash it offline to prove nothing was altered. Independent customer verification of the audit trail is uncommon in this category, and it is the part security and audit reviewers care most about.

The runbooks themselves are deterministic TypeScript orchestrators rather than generated output, so the same request produces the same sequence of API calls every time.

Why should a person choose your product over its competitors?

AscendCore's answer:

Three things you can verify before you talk to anyone:

Published pricing. Core is $4 per user per month and Professional is $8, listed publicly at ascendcore.ai/pricing. No call required to see a number.

Days, not months. Self-serve onboarding with no certified-partner engagement. Observe mode can be live in under 2 hours, and a 30-day pilot is included with no credit card.

Governance you can check yourself. Open the live demo at ascendcore.ai/demo/dashboard/governance without signing up, click Verify, and watch the audit chain re-hash from genesis.

Honest scope: AscendCore is not a full ITSM system of record. There is no CMDB and no complete ITIL suite. If you need those, keep your platform and run AscendCore alongside it as the approval-first action and orchestration layer.

How would you describe the primary audience of your product?

AscendCore's answer:

Mid-market IT teams, roughly 500 to 3,000 employees, running a modern identity and endpoint stack (Okta or Microsoft Entra ID, Microsoft 365, Intune) and absorbing high L1 ticket volume without matching headcount growth.

Typical buyers are IT directors, IT operations managers and CISOs who need automation that can pass an audit, not automation that acts on its own.

The second audience is MSPs, VARs and systems integrators running L1 queues on behalf of their clients, who want to automate that work without replacing the ITSM platform each client already runs.

What's the story behind your product?

AscendCore's answer:

AscendCore was founded in 2026 in Pittsburgh, Pennsylvania, and incorporated as a Delaware C-Corporation.

Founder Jacob Kelly spent a decade on the go-to-market side of enterprise IT services, sitting in the same buyer conversation over and over. One pattern kept surfacing: a large share of service-desk volume is a short list of repetitive identity and access requests, and the teams handling them were not short on intent to automate. They were short on a way to automate that their own security and audit reviewers would sign off on.

Most tools failed that review the same way. They either asked the customer to hand execution authority to a model, or they produced no evidence a reviewer could independently verify. AscendCore was built from the opposite constraint: assume every action must be approved by a named human and provable afterward, then make that path fast enough to be worth using.

Which are the primary technologies used for building your product?

AscendCore's answer:

TypeScript end to end. The application is Next.js, deployed on Netlify's US edge, with Postgres (Neon) backing the audit chain and operational data.

Runbooks are deterministic TypeScript orchestrators held in version control rather than model-generated steps, so execution is repeatable and reviewable.

Intent classification uses a hosted large language model confined to one job: turning a natural-language request into a structured intent. It holds no credentials and has no execution path.

Integrations are direct API connectors to Okta, Microsoft Entra ID, Microsoft 365, Intune, Slack, Microsoft Teams, Jira Service Management, Confluence and ServiceNow. Inbound webhooks are verified with HMAC-SHA256 for Slack and JWT validation against the Microsoft Bot Framework JWKS for Teams.
