Execution Plans
Before your agent acts, Bellowa proposes a step-by-step execution plan. Review it, approve it, or let it run autonomously.
● Everything your agents need
Built for agents. Loved by developers.
From smart tool resolution to sandboxed execution, every feature is designed to make your agents more capable, more reliable, and easier to ship.
SMART TOOLS
Your agent finds the right tool. Every time.
“list sentry errors and create linear issues”
→ resolving…
✓ SENTRY_LIST_ISSUES
✓ LINEAR_CREATE_ISSUE
Intent-Based Tool Resolution
Describe what your agent needs to do in plain language. Bellowa resolves the right tools, in the right order, with the right parameters.
No hardcoded tool lists. No manual configuration.
Built-in Guardrails
Rate limiting, permission checks, and input validation happen automatically so your agent stays inside safe bounds.
Context-Aware Filtering
Only tools relevant to the task are surfaced. No irrelevant clutter and no context-window bloat.
AUTHENTICATION
OAuth that just works. For every user. Every app.
# One line. That's it.
connection = session.authorize("github")
# redirect URL, token exchange, refresh handled
Fully Managed OAuth Flows
Connect to any app with a single line of code. Bellowa manages authorization URLs, callback handling, token exchange, and automatic refresh.

Automatic Token Lifecycle
Tokens are encrypted, refreshed proactively, and monitored for health so your users stay connected without manual recovery work.
session_alice = bellowa.create(user_id="alice_123")
session_bob = bellowa.create(user_id="bob_456")
# isolated auth, tools, and sandbox
Per-User Authentication at Scale
Each user gets an isolated auth context so their agent always acts with the right accounts, scopes, and tool availability.
OAuth 2.0API KeyBearer TokenBasic AuthJWTSAML / SSOCustom HeadersSession CookiesmTLS
Every Auth Method, One API
OAuth 2.0, API keys, bearer tokens, JWT, SAML, custom headers, session cookies, and mTLS all map into one consistent developer surface.
EXECUTION ENGINE
Run tools as code. In sandboxed, parallel environments.

run_bellowa_tool('SENTRY_LIST_ISSUES', project='api-prod')

filesystem/results/classification.json
Parallel Execution
Run multiple tool calls simultaneously inside isolated environments and collapse slow serial workflows into fast batches.
Navigable Filesystem
Large tool responses land in a virtual filesystem so agents can browse and selectively read data later.
Ephemeral Sandboxes
Every execution runs in a fresh environment with no state leakage between users, runs, or teams.
Sub-LLM Invocations
Sandboxes can call back into language models mid-execution to classify, summarize, or decide the next step.

Request an integrationSECURITY
Enterprise-grade security. No enterprise-grade headaches.
Bellowa is built for teams that need strong controls without slowing down developers. Keep data isolated, execution predictable, and security reviews straightforward.
Bring Your Own Cloud
Deploy into your own AWS, Azure, or GCP environment with isolated networking and data boundaries.
Zero-Day Log Retention
Sensitive execution data can be processed without lingering logs, transcripts, or payload history.
Granular RBAC
Control who can create sessions, connect apps, review plans, and manage production credentials.
Sandboxed Execution
Every run stays isolated inside ephemeral environments with no cross-tenant state leakage.
Full Audit Trail
Track approvals, tool calls, auth events, and execution history with exportable audit records.
SOC 2 Type II & ISO 27001
Compliance-backed controls support procurement, vendor review, and enterprise security sign-off.
DEVELOPER EXPERIENCE
Five lines of code. Infinite possibilities.
PythonTypeScriptcURL
from bellowa import Bellowa
bellowa = Bellowa(api_key="bw_...")
session = bellowa.create(user_id="user_123")
tools = session.tools(intent="manage github issues")
connection = session.authorize("github")
Framework Agnostic
Works with OpenAI, Anthropic, LangChain, CrewAI, AutoGen, Vercel AI SDK, and custom stacks.
Obsessive Documentation
Every tool, every parameter, and real examples are documented so teams can move from sandbox to production quickly.
Type-Safe SDKs
Strong TypeScript types and Python hints keep developers in flow and catch issues before runtime.
REAL-TIME
Your agents don't just act. They listen.
Triggers let your agent respond to real-world events automatically. A new email arrives, a PR opens, a customer payment fails — Bellowa fires the trigger and your agent handles it.
- Event-driven architecture with managed webhooks
- 200+ trigger types across connected apps
- Configurable filters so agents only wake up when it matters
- Guaranteed delivery with automatic retries
