## Pig

Pig is infrastructure for automating Windows applications with AI. Rather than scripting rigid UI selectors, Pig uses a computer-use agent that perceives the desktop and acts on it the way a person would, clicking buttons, typing text, and taking screenshots to decide what to do next. That makes it usable on legacy and desktop-only software that has no API of its own.

The product ships in three layers so teams can start simple and go deep. Pig Chat is a familiar chat interface where you connect machines and prototype workflows without coding. The Agent API exposes the same computer-use AI for programmatic task launching. For teams building their own agents, the low-level SDK provides primitives like click(), type(), and screenshot() that you can wire into your own control loop.

A defining design choice is that automations are self-hosted by default. You subscribe your own machines as workers in the Pig system, so sensitive workflows run on infrastructure you control rather than in someone else's sandbox. Pig also treats human oversight as a first-class feature: an agent can yield control to a human operator for a critical step and then await control to resume. It is a developer-focused tool with no public pricing, so interested teams talk to the vendor directly.

**Pricing & Plans:** Pig does not publish public plan pricing. The site directs interested teams to choose a path from the docs or to talk to the team directly. Contact the vendor for a quote.

- **Chat interface:** Pig Chat connects your machines and lets you prototype automations through a conversational interface, no code required.
- **Agent API:** The Agent API exposes the same computer-use AI behind Pig Chat so you can launch tasks from your own services.
- **Developer SDK:** A low-level SDK provides the base toolkit for building custom agents, using natural tools like click(), type(), and screenshot().
- **Humans in the loop:** Agents control the screen the way a person would, transferring control to a human operator for critical steps and picking it back up afterwards.
- **Self-hosted machines:** Automations run on machines you subscribe as workers in the Pig system, keeping execution on infrastructure you control.

**Limitations:** Windows-only, so macOS and Linux automations are out of scope; No public pricing, so cost requires a sales conversation; Building custom agents with the low-level SDK assumes real engineering experience

## Vapi

Vapi gives engineering teams a managed stack for real-time voice agents. Rather than stitching together a speech-to-text provider, an LLM, a text-to-speech vendor and a telephony carrier, teams configure those pieces through Vapi's API and dashboard. The platform handles the low-latency orchestration, barge-in handling, and call routing that make a natural back-and-forth conversation possible.

Beyond the raw API, Vapi ships observability and evaluation tooling: call logs, transcripts, effectiveness and compliance monitoring, and call simulation so agents can be tested before they reach customers. Integration hooks let agents read and write to CRMs, calendars, ticketing systems and internal APIs, which is what turns a demo bot into a working support or scheduling agent.

Vapi targets both individual builders who start on free credits and enterprises that need contractual SLAs, SSO/OAuth/RBAC, HIPAA-eligible handling and dedicated engineering support. Pricing is metered by the minute, with model costs passed through at provider rates.

**Pricing & Plans:** Usage-based. New accounts get $5 in free credits; Vapi hosting is prepaid at about $0.05/min with transcription, LLM and voice billed as pass-through provider costs. Optional success packages: Core at $29/month, Pro at 10% of hosting fees with a $999/month minimum, and a custom Premier tier for enterprises. Add-ons include extra concurrency at $10/line/month and HIPAA handling at $2,000/month.

- **Unified voice agent API:** Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
- **Managed low-latency orchestration:** The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
- **Built-in telephony and numbers:** Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
- **Testing and observability:** Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
- **Enterprise controls:** SOC 2, HIPAA and PCI aligned options, SSO, OAuth2, RBAC, zero data retention, uptime SLAs and dedicated deployment support.

**Strengths:** API-native design with full control over models, prompts and voices; Real-time infrastructure, telephony and monitoring handled for you; Transparent pricing with model costs passed through at provider rates; Strong enterprise feature set including compliance, SSO, RBAC and SLAs

**Limitations:** Total cost climbs quickly because hosting, models and transport are billed separately; The Pro success package has a high $999/month minimum; Advanced configuration assumes real development resources
