Best alternatives to Speakeasy in 2026
As companies let AI agents like Claude or ChatGPT plugins take real actions inside their business — reading files, sending emails, touching customer data — someone needs to control which agents are allowed to do what, and watch for AI agents that leak sensitive data or get tricked into doing something harmful. Speakeasy builds tools for exactly that job: think of it as a security guard and a logbook for a company's AI agents, making sure only approved ones are running, watching what they do in real time, and keeping a full record for when something needs to be investigated. Speakeasy's current flagship product is an AI control plane that extends existing identity providers — Okta, Entra ID, Auth0, WorkOS, Google Workspace, Ping Identity, SAML, OIDC — to cover AI agents, MCP servers, and AI Skills, enforcing policy in real time on every prompt, response, and tool call, and detecting threats like prompt injection, PII exposure, and credential leaks, all backed by full audit logging and SOC 2 Type II / ISO 27001 certification. Separately, Speakeasy still maintains its original product line: turning OpenAPI specs into production-grade SDKs in 10 languages via a standalone binary that supports fully air-gapped generation, a legacy it built before pivoting toward enterprise AI governance.

#3
A tool that sits between you and ChatGPT (or Claude, or Copilot) and swaps out anything sensitive you type — names, medical details, account numbers — with realistic fake stand-ins before it ever leaves your computer, so the AI still understands your ques
privacypal.ai
- ✓ On-device interception and substitution — zero-knowledge architecture, nothing sensitive sent to PrivacyPal's servers
- ✓ Covers the 5 major AI assistants (ChatGPT, Claude, Gemini, Copilot, Grok)
#4
A security tool for IT teams that answers a question most companies can't: which of the hundreds of apps and AI agents connected to our Google Workspace, Salesforce or Slack actually have access to what, and are any of them behaving suspiciously right now
obsidiansecurity.com
- ✓ Covers both classic SaaS security posture (SSPM) and AI agent governance in one platform
- ✓ SOC 2, ISO 27001, ISO 27018, ISO 42001 certified — serious compliance depth
#5
A login system for apps that need a crypto wallet behind the scenes — users just sign in with their email or a fingerprint like on any normal app, and Magic quietly creates and manages a real blockchain wallet for them, so nobody has to deal with seed phr
magic.link
- ✓ Non-custodial wallets provisioned via a simple email/social/passkey login — zero crypto friction for end users
- ✓ 6 years of operation and 53M+ wallets already provisioned — rare longevity in crypto infrastructure
#6
A tool that lets employees and customers log in without a password at all — using something like a fingerprint or device unlock instead — which also means there's no password for a phishing email to steal, and no forgotten-password calls for the help desk
hypr.com
- ✓ Passwordless authentication via FIDO2 passkeys, phishing-resistant by design
- ✓ Dedicated identity verification for help-desk recovery calls — protects against social engineering
#7
A security tool for the passwords nobody thinks about — not the ones humans type, but the ones baked into scripts, servers and automated jobs that quietly run forever with the same credentials, which is exactly what attackers look for.
defakto.security
- ✓ Built on the open SPIFFE standard instead of a proprietary protocol — no vendor lock-in
- ✓ Short-lived, runtime-issued identities instead of static, permanent credentials

A security layer for companies that let AI agents take real actions on their behalf (booking things, editing databases, sending messages) — it steps in at the exact moment an agent is about to act and checks whether that action is actually safe to run, in
codeintegrity.ai
- ✓ Deterministic runtime controls applied at the exact moment of agent decision
- ✓ Credible team — publicly demonstrated compromising Notion in under 4 hours (covered by The Economist)
#9
A login system that replaces passwords with a cryptographic key tied to your actual device, so there's simply nothing for a hacker to steal or guess — and it now also checks whether the person or AI agent on the other end of a video call or API request is
beyondidentity.com
- ✓ Passwordless authentication cryptographically bound to the device — nothing to phish or steal
- ✓ Continuous device health verification, not just a one-time login check
#10
A middleman service that lets an AI agent safely log into your other tools (Gmail, Slack, your CRM...) without ever handing it your actual passwords or API keys — the agent gets a narrow, temporary, revocable key just for the one task it needs to do, and
alterauth.com
