Pros & Cons
Retell AI
Pros
- Reviewers repeatedly praise natural, low-latency voices and smooth handling of interruptions.
- You can choose among LLMs and TTS providers per agent and trade cost against quality.
- There is no platform fee, billing is per second, and failed calls are not charged.
- Compliance coverage is strong: SOC 2 Type 2, HIPAA with a BAA, and GDPR, with PII redaction built in.
- Native connectors for HubSpot, Go High Level, Make, n8n, Twilio, and Vonage, plus free SIP trunking.
- G2 shows a rating of about 4.8 from thousands of reviews.
Cons
- Custom functions need code, so non-developers face a real learning curve.
- Costs stack across engine, TTS, LLM, telephony, and add-ons, which makes monthly spend hard to predict.
- Testing is billed at production rates, and there is no free sandbox.
- Some Trustpilot reviewers report slow support routed through Discord.
- SSO and HIPAA BAAs require the custom-priced Enterprise plan.
Visual Studio Code
Pros
- The editor is free, and signing in with GitHub automatically enrolls you in Copilot Free, so you can try AI coding at no cost.
- You can choose the agent harness (Copilot, Claude or Codex), bring your own API key or use a local model.
- MCP servers, custom agents, skills, hooks and prompt files let teams shape how the agents behave.
- An independent test found strong GitHub integration: the agent read an issue and fixed a race condition on the first attempt.
- Administrators can restrict agents, models and tools on managed devices through enterprise AI policies.
Cons
- Agents run commands in the local terminal, so they could run destructive commands if a user approves carelessly.
- A tester found the agent missed cross-package dependencies in repositories with 200 or more files and produced shallow happy-path tests.
- The companion app and parallel worktree sessions were Insiders-only as of May 2026.
- Copilot billing has moved to AI credits and reviewers report conflicting price information, which makes costs hard to predict.
- Bring-your-own-key does not cover inline suggestions, semantic search or embeddings, so a Copilot plan is still needed for those.
